4l80e log lockup seems to be slipping Well I finally decided to hook the scanner up to my car to see if I could figure out whats going on. Here is a copy of my log and im pretty sure it through the 1870 code trans component slipping not sure whats going on. Tcc duty cylcle is 96 percent and the tcc slip is around 79.9 - 80.00 percent.

Yea then it stopped locking it seemed when that code came on or right before. Im not really sure whats wrong I dont think its programming anymore. Btw what is a shift time error? I dont know why lockup could be slipping everything else seems alright besides my shifter lights on the console being out and my pinion angle may not be set 100 percent yet.

Shift time error is the amount of time between comanded and actual measured shift.
I would get everythng else working including the console light and the TPS correct and then work from there , You will likley get the most help on HPTUNERS FORUM I have found alot of good information there.

Yea im not sure why the console lighting isnt working. I think the tps is fine. just the pinion angle maybe be off alittle bit. The tranny seems to shift fine. I will most likely have to pull the trans out again for some reason because thats my usual luck. I think I ended up pulling my 4l60e a total of 5-6 times. Im glad it seems that I have a transmission builder that actaully wants to help and knows about ls1 cars.
