HI I HAVE A 1991 CAMARO 305 TBI AND A 700R4 TRANNY AND I JUST NOTICED THAT THERE IS A PLUG ON THE SIDE OF THE TRANNY IS OFF. THE CAR RUNS GOOD AND SHIFTS FINE I JUST WANNA KNOW IF IT WOULD BE BETTER TO PLUG IT IN. THANKS

 

If it's a 4 pin plug, it's for the torque converter clutch, and you'll want it plugged in.

You'll also want to turn your caps lock off.

 

It should be plugged in, but if someone unplugged it on purpose it could be because the torque converter clutch solenoid is bad. Unplugging that plug is a quick fix for TCC problems.

 

THANKS FOR THE INFO. WHATS WRONG WITH MY CAPS? THEY WORK.

 

WHAT KIND OF DIFFERENCE WOULD IT MAKE IF I PLUGED IT BACK IN? THANKS

 

When you type in all caps it's annoying, offensive, more difficult to read, and it makes people less likely to reply.

 

All caps is bad netiquette.

If the solenoid is bad and you hook it back up, it could stall coming to stops. A new solenoid is fairly cheap and not all that difficult to install. If you leave it disconnected you could potentially damage the torque converter or the transmission, which would be a much more difficult and costly repair.

 

i am having that problem now i just rebuilt the whole engine to factory specs. the car stalls when i go to stop most of the time. the engine has all new parts like plugs, wires distributer and cap n rotor and ignition module new o2 sensor and map sensor. timming is at 0 then i tried 2btc and it still runs a little rough and stall. do you think its because the tranny plug? thanks.

 

The TCC wiring won't affect any of that.

 

Sorry to bring up a dead thread put i have a three pin plug hanging down by my transmission, runs along the firewall. its orange in color and 3-pin offset and i have no clue where it goes and if its even for my transmission. car runs and drives fine, shifts smooth but stumped to find out where this goes and what its for. any help would be great, thanks!

 

it goes nowhere. The harness accomodates more than the combo in your car.

 

So I shoulldnt worry about it hurting my car at all? Just was bugging me cause I couldn't figure out where it went.

 

correct. there is 1 electrical connector on the tranny and that's for the tc. You said that is connected so you are good to go

 

2 electrical connectors on a 91...one for the TCC and one for the VSS.

 

Sorry it took so long to reply but where is the VSS located? The plug is just hanging there still and I don't think its affecting anything. The wire is short to, barely gets to the bottom of the engine compartment. Only problem I'm having with my car is it has a rough idle when hot starting. This shouldn't be the cause right? Can post pics later maybe

 

In the side of the tailshaft housing.

 

The VSS is vehicle speed sensor. It replaced the mechanical speedometer housing. It is in the rear part of the tranmission called the tailshift like Apeiron side. On the drivers side of vehicle.

 

Well that plug definitely doesnt go there lol but thanks for the help and info! Learning new stuff bought my car every day!
