Greetings!

I've bought my first gen 3 Camaro and it's a 1984 Z28 HO. I've previously owned older Camaro's and birds and I am new to Camaro's with ECMs OBD1. I'd like to delete the "XJY" A.I.R. system and replace the quadrajet either with an older non-ecm Qjet or a holley. However, after perusing the forums a bit, i've seen that certain TR400 transmissions have TCC. Obviously having TCC would through a fast hard wrench into my plans to delete the ECM. Does the 1984 have that? I looked at the wiring diagrams here Thirdgen Vacuum Line Diagrams - Austin Thirdgen and i don't see the "trans conv switch." I also saw on an el camino forum that the only thing the ECM did on the 84 camino was to control the carb and the timing.

 

The TCC Systems of this era operate on "Electric Circuits" and not "Electronic Circuits" so no ECM or any kind of Controller is required.

Only basic 12V Circuits.

 

Thank you for answering Vorteciroc! So i can safely disassemble the AIR system (as long as i replace the dizzy and the carb) and disconnect the ECM?

 

Yes, the ECM is not required for the TCC System to Operate.

The Transmission will have a 3-Wire Set of Circuits coming from the Electrical Connector on the Transmission.

Use of which only needs the Brake-Pedal Switch (already there) and an Adjustable Vacuum Switch (you will need to Obtain) and you will be good to go.

 

Ahhh... ok so I need a 700r4 "lockup kit?"

how is it currently hooked up and able to lock up? via the carb? Thanks again! I've only tinkered with TH350's on older chevys.

 

If your setup is stock, the ECM grounds the circuit for the TCC at the appropriate speed.
I put a lock-up kit in mine from Monster Transmission. It was easy to install. It locks the torque converter in Overdrive only, and unlocks whenever the brake pedal is applied...
