So heres a question for you guys. So my tranny was rebuilt 2 years ago almost to the day and is now starting to slip again. Granted in asking around now it wasnt the best place to get it done. but here is whats happening. it started a couple weeks ago when the high temp. was about 3 and the tranny would slip once "warm", the kid before me put a 140-150 t stat in it, mainly in 3rd and od and light load (climbing a hill behind someone moving slow 40-50). you could feel it and watch the rpm bounce up a bit but id pop the gas to get it to shift and once above 2k it wouldnt slip. now that the outside temps have risen to normal (25-35) it has stayed the same. ive noticed the tranny only slips once it has warmed up and doesnt do it (or i cant feel it anyway) when its cold. could this be worn out fluid (has roughly 30-35k since rebuild and it was only autoparts plus fliud) or maybe the filter is plugging up? any help would be appreciated. im hoping i dont need another rebuild since im laid off during the winter and pennsylvania felt the need to deny my unemployment bc of new bs laws.
