Looking for help for a 700r4 tp 4l60e swap using 0411 pcm

[MikaelT]

my setup is a 88 astro with a 4.3tbi, 1998 4l60e origin unknown and a complete harness with ecu from a 2002 blazer.

so far I have installed everything and modified the bin with tunerpro to remove stuff like vats ectect.

im not sure if that could cause an issue but the rpm signal is directly taken from the distributor but according to the sanner the reading seems ok ish ( my van does not have a tach ) and tps seems to be working just fine but the trans wont do anything. Commanded gear is stuck in 3, manualy going in to first seems to be working but will not shift by it self unless I go back up in drive, and will stay in 3rd and not go in OD.

Anyone have some experience tuning a 0411 for that application ? I would like to make sure my pcm is properly programmed before looking into mechanical issue.

Seems your transmission is in failsafe mode. I would check the powers and grounds, especially the ones that go to the transmission. It should have a power wire that goes to all the solenoids and then the computer grounds the individual solenoids to achieve this shifts. No power no shifting except for park, reverse, neutral, and second gear.

To be clear you have the 88 Astro van with a 4.3 TBI, 4L60E, and have just swapped the harness and computer from a 2002 Blazer?

yes exactly, 4l60e seems to be from a 98 truck acording to the number on it.

what im not sure besidew the programation it self is if the rpm and tps are compatible even tho my scanner give me a seemingly accurate reading.
I will double check my wire right away.

I'm challenged to understand how a 4.3 V6 TBI Distributor Tach Signal is a substitute for 4.3 V6 CKP signal?

I don't actually know that the '0411 needs a factory CKP signal to operate a 4L60E. I've never tried using an '0411 for stand-alone transmission control.

I've copied / cloned / fabricated the factory way of doing things, and that has worked out for me.

I cant anwser that question but somehow I do have some kind of rpm reading on my scanner. if im not mistaken, the rpm signal is only for wot shift ? but adding the tach signal made it go into first for some reason .... right now I have all the dtc possible for the shift solenoid, tcc pwm ect ect.

are the 98 and 2002 4l60e incompatible ?! I downloaded a bin file from a 2001 sonoma as well and it was similar. I did managed to get it to start in first on Drive and shift up but it never downshifted back after that. now If anyone know a thing or two about 4l60e tuning on tunerpro can enlighten me on possible mistake I made , I could rule this out and look at the wiring or the tranny it self.

[ralmo94]

Do you have MPH reading on the scanner, and is it correct?

[MikaelT]

yes I do and it seemed close enough. hard to verify while driving and the truck speedo not working because there is no tv cable hooked up lol. but it looked like it was accurate.

[ralmo94]

Did you alter any shift tables?

Using tuner pro, right? What xdf?

Tuner pro shout generate a list of modifications that you have made to your source bin.

[ralmo94]

are the 98 and 2002 4l60e incompatible ?.

People do 0411 swaps on 98 trucks with an 03 van calibration , so from that I would say electronics should be the same.

I'm sure someone else knows better.

yes i am using tuner pro, and I basicly only modified the least possible so it could workm like vats, axle abuse and engine dtcs

[ralmo94]

What setting do you have for PRNDL ?

[MikaelT]

I beleive im at none atm, I can send you the whole bin if u wanna take a look real quick. im sure something must be going on in there, its definatly going into limp mode because every code triggers

Oddly enough, V6 tach signal is the same as a 3x reluctor and a V8 tach signal is the same as a 4x crank reluctor. There have been guys feeding the HEI tach signal into the OBS Black Box on carbureted L31s for years.

[ralmo94]

Have you verified fuses are good, and is the trans known good? Worked when pulled?

That was my understanding, does this also mean that it would be possible to 0411 swap without a crank reluctor?

[MikaelT]

yeah I checked fuse, and the ecu is scanning properly and monitoring rpom and tps like it should so Im assuming this is good.

Trans is unknown, but throwing out every single solenoid and tcc electrical code at once seems odd, and et kinda want to work like it should for a sec when I erase them. all the wiringharness is complete from a 2002 blazer. thats why ide rather make sure the programation is good or not before opening up the trans and all that.

https://sites.google.com/site/sloppywiki/everything-ls/cheap-stand-alone-trans-controller

this is what I followed, in my case, trans is already wired up to the ecu so I only spliced all the required 12v ground and sensor into the 0411 from the astro and seems to be working as it should. I could not follow the instruction on tuning since I only have tunerpro

[MikaelT]

I guess it depends what you wanna do, gotta consider all that ckp / cam correlation that vortec engine use.

[ralmo94]

Seems to me like solenoids are missing power or ground?
Maybe back probe at the trans connector to verify grounds and power is reaching correct pins?

[MikaelT]

just came across this, look like minor difference in 2002 vs 98 4l60e ? could that be an issue ?!

[MikaelT]

is there a way to to segment swap the trans config from a 1998 bin ? I know there is some on the site but I dont even know if its compatible with tuner pro

[ralmo94]

Segment swaps have to have the same operating system on parameters.

[ralmo94]

I can send you the whole bin if u wanna take a look real quick


Might not be a bad idea.

[MikaelT]

Might not be a bad idea.

there it is

[MikaelT]

it was indeed the pink wiring powering the trans that did not have 12v on it, I supose it take it from somewhere else I didnt power up in the harness, then I got the speed sensor to read something as well and im out of limp mode and actualy shifting gears ! now I cant say if the calibration are good or undrivable but it is a pretty damn good start. I will post my finding soon for the people of the future tyvm for taking the time !

[ralmo94]

looks like 12202088 OS

Glad you got it figured out.

What Size tire and Ratio are you running?

Speedo Should be pretty close if you are running 3.42's and 26 inch tires,
If running something else, would be best to have the proper VSS settings, as shifting is scheduled by MPH, not RPM

[MikaelT]

3.42 and 215/70 r15 (26.85 inch.) but yeah I will need some fine tuning, its shifting a bit too fast at low throttle, and I know very litle about tcc lock and all that stuf so I need to comfirm that it is working as it should.

I think I went with a base calibration from a 2001 s-10 2wd wich seemed closer to my astro's spec than a 4x4 blazer.

[ralmo94]

215/70-15

751.13 revs per mile

751.13 * 3.42 gear ratio
=2568.8646 trans revolutions per mile

2568.8646 * 40 pules per rev =
102754.584 vss pulses per mile.

Change HO104 TOS Revolutions per mile to 2568.87
And HO101 VSS pulse per mile to 102754

And that should get things shifting at the MPH you tell it to.

[ralmo94]

Here you can see up shift to 4th is commanded before lk in 3rd.
4th is set to lk at 46 mph
and 2nd lk is dissabled

Here is a copy of my spreadsheet I use to aid in shift schedules.

I already put in your stock tcc and shift tables for normal mode

It should help you visualize the changes you make and how it affects other parameters with the graphs.

hey man thanks ! ill try this out and let you know, merry christmass

[MikaelT]

what does 'ho104 tos' stand for ? I found the pulse per miles setting but not the other one

[ralmo94]

That's how it's labeled in the xdf I have. It's transmission revolutions per mile

TOS is trans output shaft

got it, I was using universal patcher thats why ! ill look into those table in the morning, definatly a lot of data to digest. Realy apreciate you helping me out. Just blew my 350 on my k2500 and getting this van running was my only option to have something running again. tyvm

[ralmo94]

That sucks about the 350.
Universal Patcher is an awesome tool.
I can't remember how it's labeled in UP, but I believe it's under speedometer.

The shift tables if I remember correctly are labeled 1-2 line 2-3 line, and so on. Under transmission category.

I had tunerpro installed as well, I went ahead and downloaded the xdf package and found the tab exactly as you labled them.
