I have an LS B18 engine and my tranny blew which was a gsr trany so I purchased another one and mounted it and had it alll together then went to put the halfshaft into the transmission and it went in but the 3 holes were not lined up so I could not put the halfshaft on which was weird because it all mounted up and I thought that all B series parts were compatable?... PLEASE help!!!!!!!!!!

 

Did you put another gsr tranny in or something else?

 

It is supposed to be another GSR tranny I got it from a transmission shop... its all bolted on and perfect I just can not get that halfshaft axle (the three holes) lined up
