Question about 1984 GMC Suburban
I've got an 84k-20 with a 6.2L diesel. the 700r4 was rebuilt about 12k ago. the truck had a 400turbo originally. last winter it started shifting at times at very high rpms with no shift into OD. this was very spuratic and mostly worked ok. I did a fluid and filter change with no difference. now it only shifts at max rpms, and it just slips in drive. the fluid is not burnt so what could be up. I have readjusted the tv cable and thats when it got worse. is the trans selonoid bad? or should I scrap the whole tranny/
It sounds like a Solenoid problem. It might also be a clutch pack. If you felt like cracking it open to take a look, you might be able to do the rebuild yourself because there are ample parts available, but you might be better off just finding a new used tranny.
