4l60e slipping
It's been a concern since I bought the car. The guy I bought it from said the previous owner had rebuilt it himself, and as far as I understand it he never really drove it, decided it was not what he wanted and sold it.
It drove and shifted fine when I got it, then one day it started bouncing off the limiter when going WOT. Shortly after that it started slipping when giving it more than about 1/3 throttle.
It does it in first and I think second, though I try not to give it much throttle until I get my spare trans rebuilt.
Also as weird as it sounds if I put it in manual 1st it really feels like it is slipping at any throttle when taking off from a stop, but if it's in D it takes off normal.
No codes for anything trans related.
I'll probably tear it down when I pull it just to find out for sure.
Trans fluid looks good, doesn't smell burnt
When it warms up the shift from 1st to 2cnd gets softer, sometimes there is a slight shudder when it shifts.
