I need to know do ALL b series trannys mounts up to ALL b series motors? I have a 2001 GSR b18c block and im buying a 1992 LS tranny. It should mount up correct? and will i have to worry about the splines at all cuz i have the flywheel from the 2001 gsr?

 

The tranny will bolt up, and the flywheel should be fine. However, the 92 LS was a cable tranny, so if your car uses a hydro, you'll need to either get a hydro tranny or convert it to run a cable tranny.
