5R55E Rebuild Issues
This is a little late but I need some help with my rebuilt transmission. I had my transmission rebuilt a couple years ago since it was ran dry of oil. I had a local mechanic rebuild it for me, since I didn't have the time or space to do it myself, not that I think I could have done better. A rebuild kit was bought from a local auto parts store and all the parts looked correct.
Right after the rebuild, we knew 5th didn't work. After a couple more teardowns with zero findings, I decided to run it as it was, since I needed it for work as I had no other vehicle to use.
After a little while, I decided to take it to a tranny shop to let them take a look at it. They informed me the 2nd didn't work either when in drive, which I surprisingly never noticed, but they couldn't do anything to fix it, but that it wasn't electrical. They informed me that since it was recently rebuilt with parts that weren't theirs, they would have to rebuild it again, and I definitely couldn't afford that.
Now, 2 years after it was rebuilt, nothing seems to have changed, by that I mean nothing seems to have gotten worse.
My current issues are: slow reverse when cold, no 2nd or 5th in drive, hard downshift when accelerating to pass vehicles on highway, seemingly random hard upshifts.
Does anyone know enough about these transmissions to say if mine might be fixable or if I should just give up on it and replace it?
