I finally got my car up and running after the Dizzy problem and now I got more problems. When I accelerate, I hit about 30 MPH and the car will not shift into the next gear. When I floor it, I hear a slight knocking from what I believe is the bottom of the engine. Might be a bent rod or something, but I am more worried about the tranny because I dont know how to fix those yet. Also, my kickdown cable has not been connected just yet. it wont work with my bracket.

 

Year, Model, Engine, Miles, etc.

Could be something simple as a clogged Cat

 

This smells like a SBC/TH350 combo to me. I'm no expert on old school stuff like that, but weren't those older automatic transmissions heavily vacuum dependent (thinking: vacuum modulator, etc)? If so, are all of your vacuum lines properly connected/not leaking?

 

Good point. I saw a vacuum line from the transmission not connected. I will **** with that tomorrow

 

Fixed. 03SS/00GSE/93LX, I renounce god and will now pray to you :P Vacuum line was not even there. Got it to work after connecting the vacuum line.
