Tranny issue
#1
02 ZR2 with L460E transmission. Starting out, it won’t shift out of 1st. I do it manually, and it works ok. Once it’s been running for 5-10 minutes, it starts shifting smooth as silk. Also, speedo doesn’t work right until it shifts smooth. No codes. No clue what this could be. Ideas?
