need help and manuals

Forum: 

Hello every one, my name is Alvaro and I live in Colombia South America.
Can some one help me. I am looking for the service manuals for a rocky 1986 engine 2.0L 3Y f85.
I am having serious problems with the transmmition, after replacing 1, 2nd, reverse and all bearings and synchronizers the transmmition makes a grinding noise on 3rd, 4th, and 5th gears, It does pop out first if I am going down hill.
