Ok so got the trans in disabled the Automatic transmission controls now to find a mechanical to electric speedo conversion that puts out the 40 ppm the ecm needs for the vss everything I find is 8k...

Thank you sir ! Figured it out using the EEXTRA xdf

I’m eventually going to go back to the 4l60e I’m going to rebuild it soon as soon as I’m done with another project so for the time being wanted to throw in one of these other transmissions in I can’t...

To be honest that’s part of it haha just want to get this long overdue project on the road I had the tune done a few years ago and barely got the car going the 4l60e wasn’t going into 3rd or 4th...

I’m going to just throw this th350 in the car can someone point me in the right direction of turning auto trans functions off or manual on tuner pro to run the th350

I’m using tuner pro so do I need to input my gear ratio anywhere or is it just those tables that I’d have to tweak for shift points the tune isn’t stock I sent the ecm out years back originally it...

Ok hopefully I can figure it out wasn’t there a site out there where I can plug in my gear ratio overall wheel diameter and transmission type and get all of those numbers or maybe I’m making that up...

So back to the transmission it’s not shifting right sometimes it will shift to 2nd or 3rd but everything is off I know my gear ratio that the tune originally had was for 3:42 now it has 3:08 with a...

I think ima give it one more go at attempting to figure out this 4l60e than it worked before I pulled it so idk what’s going on now. I just figured out my idle issue it was a faulty iac not too sure...

Thanks this solved it :rockon: your the man iac count was all over the place did what you said plugged it and idle dropped. I have a few extra spare parts I swapped the iac with a used one I have and...

Ok cool thanks just wanted to confirm and make sure on the engine side everything runs the same

As the title states I have a th400 that I’m thinking of putting behind my 94lt1 that’s swapped into a gbody my question is do ai have to do anything to the ecm to keep the engine running correctly or...

On another note I’m still having some trouble with the transmission not shifting properly stays in second and tcc won’t lock up using flash hack I can command the tcc to lock up and put it in 4th...

Thank you great info and gives me somewhere to start I’ll try that later today and yes it is DBC I’ll look at my data stream and see what the IAC count is and ECT

Ok so a few things I’m trying to figure out I swapped a 94 lt1 4l60e into my 78 el Camino motor seems to idle a bit to high around 1200-1300 at idle in drive and about 1500-1600 in park I have no...
