I just got the Camaro running after being down for 2 years for repair. I had a head gasket blow, and at 120xxx miles I figured freshening up the bottom end would be a good idea. Fast forward past a machine shop connection that fell through, moving from CA to NV, and getting everything plugged back in/repaired, my car runs! It just doesn't shift.

I got it out of the shop yesterday after admitting defeat on the engine. Turned out an upper plenum gasket was backwards... Now it runs! It also lost reverse, and shifts forwards like garbage(high rpms like mis-calibrated TV cable). Why all of the sudden would reverse disappear? The transmission was solid when the head gasket blew, and hasn't been removed from the car since.

When I get home from school today, I'm doing more diagnosing on the transmission. Any ideas would be appreciated. The first thing I plan on doing is checking that the TV cable is seated and adjusted properly, then I'm out of ideas. Anyone?

 

yea try pushing th TV cable all the back.
