Torque Converter

[CARdiac]

How can you tell if the TC is going bad? Under acceleration I have what feels like hesitation or actually a flat spot mid way thru the RPM range.....the RPMs keep moving but the car feels liek the acceleration has slowed fo just a fraction of a second.

I've noticed this too, I have no idea what it is, but I'll know after my new torque converter is in whether or not it is the converter.

I had the same problem,after my converter was changed the car runs much better

Roughly how much is it to replace the TC? Is it worth going to a performance one for a 3.4L?

How would a TC go bad, there are very few moving parts. Basicly there are two fan like things facing eachother and the case if filled with fluid. So unless there is a leak, how could it go bad. As far as I know they are pretty rock solid, right?

Well I guess one of the internal parts could have bent, but that would have been a lot of force right?

Actually, a torque converter can do a lot of damage to the tranny if it goes bad. Mine went bad in my IROC, when it did, it damaged the sprag, input housing shaft, and the band. I took out the torque converter and it was in really bad shape, once the TC goes out, theres a chain reaction that goes with it like with mine. Cost me a couple hundred in parts, but its worth it now because its like a new tranny. If your car makes a vibration in the gears, thats a sign of the TC too. The TC cost me about 100 bucks, but thats for a 700R4 and I dont know how much it would cost for a V6. BUT, if its not the TC you have a problem with, it may be the sprag in the tranny. That can also cause the hesitation and other things as well.
