What exactly are you trying to do ?

Go auto to 5 speed ?
Change out your tranny for a different hseries 5 speed tranny ?

Hseries (preludes) are a pain to work on because of the space you have to work w/ in the engine bay.

I have done bseries clutches in 2.5 hours w/out a lift taking my time etc. (same labor as tranny swap).

I am sure xat can manage to swap out a tranny for you. If not I highly recommend kj at zmr.
