Torque Converter???

[Back In 92]

Anybody have any problems with the torque converter switch and does anybody know if it is replaceable without replacing the whole transmission????

What happened? If your talking about the TCC solenoid, it is common in these cars for it to go bad but what happened to make you think it is your torque converter?

Well, you see, my stepdad told me it was the torque converter switch. My car would stall out and make a sort of grinding noise when i dropped it into drive and no matter how much i revved it in neutral it stalled as soon as i dropped it in. I asked my uncle who i got the car from if he ever had that problem and he told me he unplugged a "sensor" from the tranny. My stepdad said it was the torque converter switch and when i take that "sensor" out the car runs fine but i know that this could cause serious problems if i left it unplugged because it is there for a reason.

try the search button for the tcc, i just went through this with someone else. leaving the plug out of the socket permenantly will have one and only one ill effect, and that is slightly reduced gas mileage on the highway. Mine has been unplugged for over 4 years now with no problems, the tranny has 235k miles on it.

I had the same problem with my car. It is caused by the TCC Solenoid. What happens is when you get to about 45mph the TCC Solenoid opens and tells the torque converter to slip to give you better gas mileage at highway speeds. When the TCC goes bad it will stick open and when you come to a stop the torque converter stays engaged and makes the car stall. In order to fix it what you need to do is remove the side cover of the transmission and either unplug or replace the TCC Solenoid. I also recommend that you change your transmission fluid and filter when you do this. If you need any help or have any questions let me know. I just did this to my car and now it works fine.

I just changed the fluid twice because the first time the pan had a bad gasket and was leaking, and the second time we thought our problem was the with the pump being knocked loose or something. As far as the TCC solenoid goes, can it simply be replaced and if so how and how much approx?

[93GASE3300]

Its good you changed your fluid allready that way you dont have to do it when you do your TCC. As for the TCC it will fix the problem and should cost approx. 40 to 50 dollars at any GM dealership, Whether or not they have made an aftermarket one or not is beyond me however I only recommend using oem parts.
Let me know how everything goes.

id like to make a correction. The torque convertors in these cars are lock up torque converters which means when your driving about 45 the torque converter locks up with a 1:1 ratio. It doesnt slip at all I was thinking about the trans in cadillac (being so I work on them) that are allowed to slip which can give a lower ratio and therefore giving better gas mileage. You really need it on those gas hogs.

I returned a code 39 when I did codes a couple of weeks ago. The definition I found was "Torque converter clutch slipping." I admit to not being the brightest person when it comes to cars, especially transmissions. Is this a similar problem that might be alleviated by replacing the TCC? What the heck does TCC stand for, anyway? Please forgive my naivete.

if your torque convertor is slipping than it is not in good shape. TCC stands for Torque Convertor Clutch and in this transmission the torque convertor is supposed to lock up and if it slips it is not a good thing. If it does slip you may need to replace the torque convertor in conjuction with the TCC solenoid but thats not a firm suggestion. You should have someone look at your car and diagnose whether the torque convertors condition is in.
