Well I finally did the swap! B18B with GSR transmission! It is defiantly a big difference from the last motor. Well as I decided to do the famous test drive, I couldn't put it in reverse!!! So I went through the gears and I cant even go into 5th!!! Every other gear is fine. Fluid levels have been checked and its a go on fluid. My question is, what are some possibilities for this happening? Also can a bent shift linkage do this???

The person I bought the transmission from, swears that it worked when he had it... (I was expecting that answer)

 

i had a gsr that wouldnt go into 1st, or 2nd.
it just happend oneday out of nowhere, then started working after 45min of messing with it. then one day it did it after i got on it... my boss gave me 250 for it ... it had a broken shift fork i think...?

 

5th/Reverse slider could be locked up. Low fluid seems to take them out.

 

Thanks for the replies...
