Having problems with your 1989 GMC K1500 ?
I have a 1985 chevy 3/4 ton with a turbo 350 that works in all gears except drive. put it in reverse, it goes backwards. put it in 2nd, it starts off in low and shifts to 2nd, and down shifts from 2nd to low, just like it should. put it in drive, no go. why?
Very possible you have a internal fault in the drive gear only.I would suggest that you remove it and have it rebuilt.We have a local company that rebuilds them for around 300 dollars.
