i have an all original (to my knowledge, only 2nd owner and bought last year) 1982 Rx7. It has been seemingly losing power over the past week or so. I figured it had somehting to do with the sparkplugs needing to be replaced, and just hadn't gotten around to it yet. Now today it has no power to the wheels.

It doesn't feel like it goes into gear. There is plenty of hydraulic fluid. The engine itself has power and revs. But no reverse and no forward.

if anyone has any suggestions as to where to trouble shoot or what to check i'd appreciate it.

thanks.
