Bad Torque Converter??????????

[Michael Farmer]

A few months ago I bought this 1990 Chevrolet Beretta GT just for a drive around town car. When I first got it, I had to replace a torque coverter switch down on the side of the engine, because the car would jerk like it had a stick shift in it when you slow down and forget to push the clutch in. Anyways, I think the car had been driven awhile with this bad switch which may have caused the problem that I have now. Mostly the car jerks while in the 45mph to 55mph range. Anything below or above those speeds it drives like a dream. Could it be that the torque converter was damaged during this time that the switch was bad? Because it acts like a sloppy converter, and always seems to be acting up when the converter is trying to lockup in the 45 to 55mph range.

252,000 on engine, I believe this transmission has roughly 180,000 on it.

I believe your 46RE is eligible for a worn clutch based on the high mileage.

I’ll let you know if the shaking goes away once my misfires are fixed. This transmission isn’t getting fixed, its simply not affordable, so if that clutch is worn then we’ll be dealing with it as we have for a few months.

[quote=”LJ11194″ post=33429]Thanks alot. I don’t really know which of these would be best to do though. I’m only at a basic level with mechanical work and I don’t touch electronics much beyond plug and play.

It’s also worth noting I have occasional misfires in 3 cylinders. They only throw CELs above 4 grand but I’m pretty sure they’re always there. I have a blown plenum gasket and recently ordered the kit to fix it, (its coming tomorrow, who knows when it’ll be installed though) so would it be worth seeing if the missing is causing the TCC to slip? I know for a fact that it only shudders when the TCC is locked, so it isn’t JUST the missing.[/quote]

Seriously this would have been information that should have been in your original post. Try to avoid making a diagnosis before you list your problem that way we can help you best. It could be that your problem is an engine performance problem and has nothing to do with the TCC.

Well this isn’t my thread… That information was fully disclosed in my thread, and I even had a separate thread about the misfires which is where the blown plenum was diagnosed.
