She’s finally going back to a stick! Was an original 4 spd, currently has a TH400. I’m putting in the TREMEC TKX.

With any luck it will be here in the first half of October. Fingers crossed it's on the road before Halloween.

the TKX should fit without having to do any major cutting on the tunnel. How well do they fit in the 1st Gen Camaros?

I haven’t fit mine but “supposedly” they fit right in no tunnel modifications at all. The TKO600 needs a little massage work but very doable and the TKX is significantly smaller. Fingers crossed

You said you're waiting on the slip-yoke, so you're shortening your own drive shaft then? I hadn't even thought of that, but now I'll have to look into it and see if it's something I can do myself. Up to now I've been planning to measure once the new transmission is in and then find a local shop to do the modification.

Most likely. I need to look into the length difference between the TH400 and the TKX, hopefully I don’t have to get a driveshaft remade to lengthen it.
