4l60e trans problems

[chrizar]

so for a bit now my trans won't shift from 2-3 under more than half throttle and now is acting up in OD acting like it's kicking in and out of gear.

took the car for a drive to the bank today to log what was going on, and figured i'd post what I have for now. I need to log it more to get an actual reading on trans temp over a longer drive but maybe someone can see something in this log that I don't.trans data.uni

When mine did that I was told it was the 3-4 clutch pack going bad. Under light throttle it drove normally but under full throttle it wouldn't shift into 3rd. Would still shift 1-2 under full throttle fine.

I'm betting the 3-4 clutches or a band is shot, but damn the trans only has 85k on it. Well if the miles were correct from the guy i bought it from.

After more digging into this, I've found that I had a rubber line swoolen up and leaking just a little bit. (had to make new hard lines and a make shift piece to the bottom of the radiator for the trans cooler) Noticed it leaking fluid on the ground last night at work, added extra and now it's shifting fine. So This weekend I'm making a new hardline to run to the front of the car as one piece and it should be fine.
