Hello everyones, 91 z28 305 tpi, auto, was going down the road and I lost 3rd and 4th gears, I can shift into 1,2, d, od, but 1 and 2 work ok, but when its in d or od it stays into second
any help... thanks

 

I belive its probally shot but this is just a guess

 

Indeed it is. I've had two 700r4's do this, and both needed a rebuild. Get a shift kit and a urethane tranny mount while you're at it, if your wallet allows (should cost about $200 for both of those things.) They're handy to have if you do alot of heavy acceleration, and will improve the life of the tranny as well.
