Hi, ive recently restored an 89 305 camaro. Some one has removed the ecu and all wiring now on carb. I have re-wired the car so all works but there is a plug on the gear box and i havent got a clue what its for. There is only one problem with the car and its the gear box, wont change gear till its nearly on the red line!!
is this related to the plug? Any help will be appreciated. gaz

 

Plug it in and see what happens.

 

Sorry, the plug from the wiring loom is not there. could make a plug but am not sure which pins are for what? and are the electronics req inside the box. i was always under the impression it was all hydraulics

 

hay gaz welcome to the forum, i have moved your thread to the 3rd generation general section for you, the guys here should be able to help. HO HO HO, hope you have a great day.

 

"Gear box" reefers to a manual transmission, is that what you have?
Now if you meant to say you have an automatic trans, the plug on it would be for the lockup torque converter.
That doesn't affect shifting points though, but the TV cable that might not be connected, or not set right, sure would.

 

Hi, school boy error (lack of discription). Its an AUTOMATIC, 3 speed with overdrive. Ive manualy operated the tv cable and i can feel the resistance at the other end. I ve disconnected the cable from the carb and tried it but no difference. I have removed the sump from the box, fluid clean and filter new. Are there any checks i could carry out with the sump removed? I'm a truck mechanic but hands up i've never stripped an auto box feel a bit daft but ave never heard of torque converter lock, what is it and is it needed?? Thanks gaz

 

Buy a Haynes manual for the model and have it for reference.
If professional truck mechanic, use the shop's manuals for a '90 and later GMC/CHEV pickup and follow instructions for the auto trans as it is basically the same.

Applying battery power to the torque convertor locks up a clutch internally giving a 1:1 ratio rather than a fluid slippage common with t/conv's. The power does go through the brake pedal to bring the t/conv out of lock-up. A simple toggle switch for power can be set up for testing.

If an ohmmeter is placed across the two terminals on the trans, you would read coil resistance of some value - a good point.
