ok so i have a j1 trans in my 1990 hatch on a b16a. i had a shop instale a quaife in it before i put it in not knowing anything about the trans. they said everything in the trans was good with no probs actually looked newish. well when i put it in it wouldnt go into reverse, well it pops out. so i pulled it back out and took the trans back apart and everything seems fine and u can slick it in when its out of the car but it just doesnt seem to click in when its in the car so i replaced the linkage with hasport same thing

the car has brand new hasport mounts.
has act 6 puck disk
hydro type r flywheel and pressure plate
new axles

ok so when u put it in reverse it never feels like it goes all the way in and when u try to back up it pops out.

need some ideas this is about to drive me crazy

thanks in advance
