Good day gentlemen, started scanning the ol' 4L60e truck transmission, trying to dial it in, but,...left me seeking y'all's expertise on two questions.
First, when I look at the scanner channel selector PID list, it provides on/off status's for:
- Shift solenoid 1-2
- Shift solenoid 3-2
- Shift solenoid 3-4 (bingo,... there's the first question...a 3-4 shift solenoid doesn't exist in a 4L60e,...is this supposed to be the 2-3 shift solenoid? Simply mislabeled on the PID list?,..... I scanned using this 3-4,... incase it actually was the 2-3 solenoid)
Which kinda leads into the second question (given I don't know if something may be wrong with the 3-4 PID above);
Sitting in my driveway this morning, I started scanning the transmission,...simply cycling through the shift lever PNRD321,...(sitting still - I know you can only get to 2nd gear doing this but),...what I saw, made me not take it for a drive for further scanning,....
It revealed;
- Park, Neutral, Reverse - shows: 1-2 solenoid on: 3-4 (2-3?) solenoid on,.......P,N,R, are good per my GM shop manual (if that 3-4 is actually the 2-3)
- 1st gear - shows: 1-2 solenoid on: 3-4 (2-3?) solenoid on,......this is also correct per the GM shop manual (again, if that 3-4 is actually the 2-3)
- 2nd gear - shows: 1-2 solenoid on: 3-4 (2-3?) solenoid off,... (bingo,...there's the second question,...this is not correct - it should be opposite with 1-2 off and 3-4 (2-3?) on.
My 3-2 solenoid stayed off the entire time (as it should). I wasn't brave enough to drive to get any further gear info,....
There's only 353 miles on this new trans and, per my previous posts, I've had issues from day one.
Attached is a copy of my trans scan this morning, and a copy of my tune,...its a 96 K1500 with 0411 PCM swapped. The first 1/4 of the scan is me simply sitting, waiting for the truck to warm up,...then I start shifting through all the gears back and forth,...you can see the PRNDL status and Trans current gear moving around.
How would I know if this transmission tune is actually for a 4L80e instead of a 4L60e? I read 'the above solenoid on/off issue (2nd and 4th gears)' would be arse-about if it was a 4L80e tune running a 4L60e trans.
I sure hope this is something dumb I'm doing, and/or an easy fix. I've already triple checked the 0411 swap wiring.
Thanks for any help guys.
