Yeah my '87 Iroc-z had the trans go shift kit installed in it when I bought the rebuilt tranny and I never had any issues with it shifting bad so I know hands on it does its job
As far as the 700 that's in my truck, for some reason it decided to start shifting into 3rd, but skips 2nd and I havent gotten a chance to see if I still have OD yet. I think this is a band issue from what i've read but idk, my original tranny in my Iroc did this exaxt same thing.
If you know any cure to that problem let me know, otherwise im thinking I'll probably just sell the truck to raise some funding for my '89 355 s10 blazer
, I have another k1500 anyway.
