What do you need to convert TH350 Camaro to 2004R?

What do you need to convert TH350 Camaro to 2004R?

This is my first draft of a write-up of the process to convert a TH350 3-speed auto LATE 2nd gen Camaro to a 2004R 4-speed Overdrive tranny. Parts you need: (Listed by the supplier I used.) Flexplate (Stock is fine. Mine was bent and needed to be replaced.) Shifter cable (The stock one should work but mine needed replacing.)

What kind of engine do I need for th350-2004r?

IMO, a 3.42 or 3.73 rear would be PERFECT with this particular tranny. Keep in mind, the way any tranny is built will give it some characteristics that may or may not work well with a certain gearing, governor or torque converter selection. It is hard to tell until you’ve bolted it to a particular engine.

What’s the best way to convert a TH350 to OD?

Nail the pedal anywhere between 30 and 60 MPH and it drops to 2nd gear, it shifts to Drive at 60 and pops into OD whenever you let off the gas. Cruising altitude is easy to maintain and a heavy foot on the pedal will slip it back to drive very smoothly.

Do you need to reinstall the CARB on a TH350?

Reinstall Carb. (The TH350 downshift cable will need to be disconnected from the carb to allow the new hardware to fit. You can still drive your TH350 but you will need to downshift manually.) Wire the car’s portion of the lock-up harness.
