Where is TCC plug 92 Cav

Hello all,

I'm having a TCC problem with a 92 CAV, and need to verify this by unplugging it. I've seen in some forums and thread mentioning just unplug it. Where is this plug located? If you could be very specific as to where and what it looks like that would be of great help. I even looked in a Haynes Manaul, and could not find it anywhere.

Sounds silly, but right now, so that it does not stall, I have actually take out the fuse for the TCC, which also knocks out my gauges, but this was just so I could get to work and search the net to find out where the darn thing is.

Thanks again for any info, 92 Cav 2.2

On top of the tranny. Just look on down there, right side of the motor, can't miss that baby blue color.

My question is, why are you bothering unplugging it? Yeah, it'll stop the TCC from engaging, but it'll shoot your highway mileage to hell. Its a very simple fix and will run you around $15 or so. All you gotta do is jack up the car, remove the wheel well paneling, and unbolt the valve-body cover. The TCC is just sitting there near the bottom of the assembly. Splice yourself in a new TCC and plug that bad boy back up, takes about 30 minutes from start to having the car rolling again.

The part is $45 at AutoZone so $15 is a little low. As for the mileage, I have never known anyone to notice the difference. My 94 has been onplugged for years now and I drive 38 miles to work. I would notice even a slight decrease. It CEL could annoy some people but that is about it.

I've never known a CEL to come on as a result of an unplugged TCC Sensor...so... you may want to check that out.

While yes, you may not notice the loss of mileage, it is there. You won't notice anything at all, of course, if you're not out on the highway. But, facts are facts, and unless both halves of the Torque Converter are mated during high speeds, then you'll loose mileage b/c of the shitty gearing in the 3-speed.

The CEL is activated by the ECM or PCM. Until the mid 1980's there was no TCC and mileage was only a little worse. Third gear is 1:1 on a three speed tranny so i do not understand what gearing you are refering too.
I believe the MPG drop is supposed to be in the range of 2%.

OBD1 TCC codes are 37, 38 and 39
OBD2 TCC codes are PO740 thru PO 745

I have a 3 speed 96 2.2l cavi, and I've definately noticed a gas difference since I've had to unplug my TCC.... and you mean to tell me there's an easy fix for this? I was told by a mechanic that it's inside the transmission! Hot damnit! All this time! It takes me just under a quarter of a tank to drive 1 hour doing 80mph!

Also, does this operation spill a ton of transmission fluid?

Damn, that is definately bad enough to justify the fix. It is an easy fix. Not in the middle of the tranny, just under the valve body cover. A Haynes or Chiltons manual should show you how. On my 94 2.2L I have not noticed any differance and it has been unplugged for several years. I would fix it just too turn off the light but time is an issue(2 full time jobs + light mechanic work on the side).

Learn to search for stuff like this.

As for mileage with the TCC, you'd only notice it if you spent time at highway speed a lot.

One does not bother searching for something like that when the mechanic says it inside the transmission and will costs hundreds.

I cant seem too disconnect the plug, would it do the same if i just cut the 4 wires???

Stop being lazy and fix your damn lockup solenoid. Its cheaper in the long run.

Can I get past the transmission mount to open the valve body cover on my 96 3-speed?

Take off your driver's side wheel well and look at what's right in front of you. The mount WILL NOT be in the way at all and has nothing to do with this fix. The only thing that might get in the way is the frame, which you fix by jacking up the motor a tad to get the last few bolts on the bottom out (I did it ghetto style with a block of wood between the a 2nd jack and the oil pan :))

Do not cut the four wires. Us with the older tranny can unplug it because we have a two wire plug and the TCC is all it does. The four wire plug does some other things, so you must fix it. Good Luck.

Err where should I put the jack? I've been told not to put in on the oil pan :(

You jack up the car on the driver's side where you're supposed to. Then, when you get the car in the air, you use a second jack, with a block of wood between the jack and the oil pan, to jack up the motor a bit. If that makes you feel really uneasy, I also tried it with the dogbone it worked just as well.

What's a dogbone!?

Well... here I go. :uhoh:

Ok... so what the hell is this? I think it was the mount! What do screws 1 & 2 go to?

That doesn't look to be a 2nd gen. So the answer would not be related to this thread.

So does that mean I can't do it?

Ok is the circled part a mount and is it safe to take off?

unbolt it. see what happens.

Umm... I'd prefer to know whether or not it's a mount before i do that! My Haynes manual doesn't show anything about the trans mount.

pussy....DO IT!

I wouldn't have nearly as much a problem with it if I had an engine lift. If it hits the ground, getting back up will be nearly impossible. :)

Bah, then engine's not going to "fall out" because of one bolt. You have a whole dang subframe for just that reason.
