Yes and no. Life has been a big interruption as of late so I havent had much time to work on it. How close are you to needing one?

Just dropping an update, or a non-update at this point. Not much has progressed due to work and home life. Looking to have some free time this month(June) so hopefully I can get this thing on the road for some rubber burning fun. As always, Im open to questions and suggestions on this project. Thanks for reading.
Buddrow
did you get the trans controlers done ? if so how much and how do I get one or what can you tell me on where to get one.......:mad1:
Skully,
Progress had slowed slightly. It's not quite ready for prime time just yet. If you wanted a barebones absolute minimum setup it would fit the bill but this thing has grown into a bit of a monster and now I can't stop until the monster is happy lol.
As for price and availability, I will post a link to the web site for product promotion and sales when the time is right. The price will be competitive with current units on the market but will likely include items not included in those units like tps setup, wire harness, etc, which mostly seem to be add-ons to the kits Ive seen. I will also be offering kits for the end user to build their own wire harness or request a custom harness as opposed to the generic harness that will likely accompany the unit.
What is your intended application, street,strip, street/strip? What trans will you be using, The 4L60E or 4L80E? Any features you would like that you don't see on current market units?
Buddrow
Well Steveo, you would be proud of me. I banged away at TunerPro and the tcm board until I got serial comms working and a single element(TPS Volt) dash working last night about the time my eyes slammed shut lol. Anywho, tonight I'm gonna finish my adx and dash setup then it's off to the xdf side. Woo Hoo!
buddrow,
thanks for the reply yes im interested in bare bones im just using it for a fuel economy setup with a 454 and a 4L80E trans and 373 gears. let me know when and how much.
Will this work with a 4T60E?
Currently is does not control that trans but it can. It "can" operate numerous transmissions from GM, Ford and Chrysler and if there is a demand I will be happy to accommodate requests. Now, with that being said, patience will be a virtue at this point as I am still working on the 4L60E/4L80E software.

Cool cool
Hello Everyone!
Well it's been months since I have posted much about the trans controller and Ive been hard at work on it. Recently I have been putting together the ADX file to use with TunerPro RT. I have attatched my adx so anyone wishing to take a look and maybe give any ideas as to what you think is missing or would like to see added can do so. Thanks for looking and have a great day.
P.S.
The adx is not complete in all ways but the dash does show all the current values coming out the datastream.
Buddrow
this thread needs some pics...
Oh, it happened all right. :innocent2:
UPDATE:
So, I'm trying to nail down any final additions before "finishing" the software for the controller. As it stands, I have implemented the following user information...
Streaming sensor data via TunerPro
Diagnostic trouble code section via TunerPo
Tuning via TunerPro
Shift light output for use with an external mounted light
Speedometer output for use with 2k ppm
Anything I'm missing that anyone would like to see?

Hi all... This is my first post here.
I am looking for a solution for my P30 (1-ton) motorhome with the 4L80e that I just converted to a 2-speed rear end.
I have two issues:
1) old problem with OD only working until kickdown (from 4-3) after which, 4th no longer exists... it just freewheels and engages 3rd.
2) Need to solve the speedo question.
I was considering a stand alone TCU, but unsure if that really is my problem.
I am considering a Dakota Digital speedo driver unit (or two), but it would be great if I could find some sort of integrated solution.
The 4L80e trans. issue of not shifting into 4th after kick down is the primary concern, of course.
Thanks!
I wouldn't mind a solution for the Dodge 46/47RE trans....
journeyman, As Robert suggested in the thread you started, looking into the data stream will provide some much needed info. Need to look and see if 4th gear is commanded by the pcm, and if not, why? May be a problem with the throttle position sensor, but there again that goes back to looking at the data.
34blazer, I plan on integrating a few Chrysler as well as Ford transmissions by the time I'm "done". My focus right now is on the GM 4L60E and 4L80E.
I suppose I will add an update while I'm here. Not much has changed with the software, on the test bench it works as desired. Hooked up to my non-E truck speed sensor and TPS, the unit operates as desired from viewing the status of several LEDs/indicators and my Tunerpro adx. Currently I am building the vehicle harness for installation into my truck. I'll try to make some videos and post links in the next week or two showing the operation of the indicators and Tunerpro dash.

hi all nice to meet you
new guy here just landed on this forum after doing a google search
i've been looking for a while for an affordable way to shift my 4L80E and i knew there was some experimentation going on with arduino boards
looks like its nearing completion and i'm looking forward to seeing the finisched product in action
if the price is right i definetely would consider buying one
eeehr the transmission i'm using is a jaguar version of the 4l80e and i have the original tcm for it too ...... it has a shitload of wires comming out of it that where originally connected to the ecm the shifter and a few other things in the car that have nothing to do with the transmission
does anyone know if this tcm can be made to work as a stand alone unit using signals from the sensors on the engine directly ?
If you can give me the year, make, model of Jag I will look and see what its connected to. Otherwise, stay tuned for further developments on my controller.
Buddrow
Still tuned in for updates. After constantly hitting brick wall after brick wall trying to find help hacking the JTEC, Im giving up on it all together. I want to build a trans controller that is arduino based and get it working so I can 86 the JTEC in favor of something with a little bit more support, maybe MSIII. I want a working controller and associated calibration. Good thing the 46/47RE transmissions are really basic as compared to other electronically controlled counterparts.
Any suggestions on what arduino to use?
Also need suggestions to drive the 4th gear, and TCC switches, and the EPC?
If you can also suggest parameters for shifting patterns too? I have some plans written out but I know theres a lot missing.
Thanks!
34blazer,
Still working on it. I will tell you that for now, the source code will not be available but support will be.
What year is the transmission you plan on using this with? I can help you identify year ranges if you are unsure as there are differnces in say 1988-1994ish, 1995-2003, 2004up. While these do not pose any real issues, it is important to know for proper control/operation.
If you're still interested let me know but don't be in too big of a hurry as this isn't my day job. :-) I can build whatever you need from the controller to the harness.

Hi Buddrow , and the rest of the people reading -
I found your thread talking about how you're building an Arduino board that controls the 4L80E. I've been trying to decide on which commercial controller I've wanted to buy for some time now and then stumbled across this you tube video where a guy is using an Arduino to control a Mercedes transmission. https://www.youtube.com/watch?v=XKrw--4Su1M
So I searched for one for the 4L80e and found your thread. I see you've been working this for about a year now, are you close to completion? My 365 ci Cadillac is running a 4l80e via adapter plate, I just need a controller. If yours is almost ready to go, I'd give it a shot.
My one suggestion for the build would be to integrate an attached display like in the video above (tuning in the car without needing a computer would be nice for some running just a carb). Maybe have the option to detach it if someone wants to hide the display? (But maybe all of the tuning is going to be done via Tuner Pro?). Eventually I'm wanting to convert my 365 to sequential fuel injection and add 1-2 turbos on it.. yes, I'm crazy. Thanks for the read, hope the project is coming along!
Alex
Alex aka HotRodCadillac,
Dig the name and the project. Glad to hear you "stumbled" across my thread. I was never really happy with the aftermarket units as a whole. They work but, much like the gentleman in the video, they seem a bit over complicated for the average gearhead. And seeing how transmissions are mystery boxes to most people anyway, I wanted to make a more user friendly version.
I could possibly release a beta version soon just keep posted. As for now, tuning is done via a terminal program and excel. I have a GUI console in the works but it is very, very early in the process. I do have an .adx for TunerPro which can be used for datalogging the controller but no tuning/programming currently(I know I posted that I had it programming via TunerPro but i must have been high lol).
Adding a "simple" LCD display wouldn't be too hard, just gotta have a demand for it, definitely keep it in mind as an option.
Oh, and I have an option for a shift light output just in case that piques your interest. Also, for now, in order to use my controller with a GM factory ecm or electronic instrument cluster, you will have to piggyback a DRAC module for the correct input signal to the ecm/instrument cluster.
Buddrow
any updates?
34blazer and to whom it may concern,
Progress has been hit and miss. I still have some testing to do and software to update on both the 4l60e and the 4l80e. If you are interested in beta testing a unit, I may entertain the idea just pm me and we can talk. Other than that, it is coming along just slowly these days with all I have going on. I have gotten another project done though, it's an electric fan/water pump controller with LCD display. It is about a month or so from being in a box but it is done. As always if you have any questions feel free to ask.
Buddrow
Hi Buddrow, I'm still watching. Hope this thing is still something you tinker with. I'll be checking back for updates. See ya!
Alex
Alex,
Yes it is still in development. Still have in vehicle testing to be done and calibration software to write. I am lookong to have it interfaced with Tunerpro for tuning but as of now it only logs data and shows dtc faults. I dont currently have a set in ston launch date but lilely after the first of the year. Stay tuned and hit me up with any questions or comments u may habe as they are always considered amd answered as promptly as possible.

Me and my father are putting together 2 projects involving 2 4L80E transmissions. Im not an expert at code or even arduino but we just purchased 2 arduino 256 boards and 2 sets of 4 channel relays. We have several miscellaneous components to go with these. I have had success in programming other automated programs in the past. Maybe i can help share your work load with the 4L80E side of your programming? I know I have to use PWM on the pressure solenoid and i know which frequencies to use. Some code to start with getting me in the right direction for automatic shifting and how you use the map sensor in conjunction would be the biggest hurdle for me. It would be real nice for us to not have to use our toggle switches anymore lol. Maybe we can help each other out?
1979 Caballero 496BBC 4l80E
1991 C1500 454BBC 4l80E
No offense, but I am not really interested in sharing the code Ive spent the last year developing at the moment.
the only real component i am working on lining out is the pressure control system. The basic shift pattern is pretty easy to figure out.I can help you out with that but the rest is confidential at least for now. PM me and we can talk more.
Buddrow
I realized it's been a while since I've posted an update so here goes.
The 4L60E/4L80E transmission controller is ready for the road. I have also been working on an alternative to TunerPro. Even Though I'm a fan, I was ultimately looking for a simpler interface which is what I have. Attached are screen shots of the interface program. It currently has "full" functionality minus some diag stuff I'm still putting together, a work in progress as always.
I can also put together controllers for GM FWD, Ford OD trans both 4 and 5 speeds and the Chrysler RWD's are soon to follow. When the TCU website is up I will post a link for interested parties. Thanks for looking.
If anyone is interested you can contact me via email or PM.
Buddrow
Neat.
Will you be releasing a TP definition? I'm thinking of the folks that have gotten used to Tunerpro but may not be comfortable learning new software.
I already have an .adx for it, havent worked out the xdf yet. The software is meant to be easy to use so there isnt much of a learning curve such as you would have with TP. As far as veiwing and logging sensor data and whatnot, both TP and my Gui will do the job. If you look back a few pages om this thread you will find the adx i built.
Buddrow
cool beans
34blazer, are you still looking for a replacement for the JTEC? I'm looking into the dodge stuff now days and could use a tester if you're interested just pm me.
"Any suggestions on what arduino to use?
Also need suggestions to drive the 4th gear, and TCC switches, and the EPC?"
Since the 46/47/48RE's only have a few inputs/outputs, you could use an UNO or even a Pro Mini or Nano. I use a MEGA which has twice the ram and almost 3 times the I/O of the aforementioned boards.
The EPC you refer to is the governor pressure solenoid which has an accompanying pressure sensor used for feedback to the tcm. On the 2003 or 2004 model 48RE Dodge used an electronic Throttle valve control on the diesel engines. The electro-mechanical TV control unit is prone to failure, pricey and mounted to bosses cast into the case so you have to use the 48RE case.
Anywho, I'll have the website up and going before long but be patient while I add product and tech info. Anyone interested or want more information feel free to pm me.Thanks for reading.
Buddrow
Yeah I'm familiar with the workings of the RE, which is simple crap compared to 60/80e or anything new. Still interested, sent you a PM.
Thanks!
do you have a web site up yet?
Yes, the site is "up". It's lacking a lot but it, along with everything else is a work-in-progress. The official website is here - http://www.bspt.tech/home.html . Don't laugh as I just used the crappy site builder the host provided. I plan to update and upgrade it as time allows.
Buddrow
Website has had a dimestore makeover, nothing earth-shattering though mostly appearance wise. Moved everything to it's own page and will continually make changes and updates to improve user experience so check back weekly at least. I'll be updating the mobile version as well. Any feedback from visitors would be greatly appreciated. Thanks for reading.
Buddrow
The transmission controller sounds awesome. Simple with full control. Keep up the good work. How much does it cost?
