My tahoe seems to have a downshift problem. Wondering if anyone has seen or dealt with this.

The transmission was rebuilt (approx 3000 miles ago) and it worked fine until about a month ago.

Here is the problem, it downshifts hard between 2-1 when it's warm. (not when it's cold, that's fine). A mechanic said that the torque convertor needs to be replaced, but wasn't that covered in the tranny rebuild?

You should get that taken back to the people who rebuilt it and have it look at. Sounds like something's not right.

Transmission shops should replace / rebuild your torque converter when you get your trans rebuilt however not all do. If it is your torque converter you will probably hear a rattle.

I would definitely take it back to who did your work.
