Torque converter causing vibration

Re: Torque converter causing vibration

This vibration thing is new. The flex plate has been in the truck the entire time. And the flex plate still has it's weight and no cracks.

I had just found an area on the outside of the TC that looked like there might have been a weight or someting that isn't there anymore. There wasn't anything in the dust shield so I didn't think that was the case. But I didn't want to assume.

I talked to a transmission place today. They have the ability to cut open converters, inspect them, rebuild them, etc. They said it sounds like the clutch in the converter has come apart. And the symptoms I have are exactly what would happen.

So, pulling the transmission would be the next step. Or you won't hear from me again if I ended up taking a trade that has been presented to me. Either way, hopefully this will be good info for someone in the future.

Next question. Does the torque converter normally have balance weghts attached to the outside? Like the balance weights on a drive shaft?

just looked at my converter a few minutes ago and the weight just happened to be facing down at me, so yes at least mine does

The transmission is out. I can now say with complete confidence that the tranny is rebuilt. All of those studs with nuts I was reading about were not there. Just normaly bolts. The tranny is painted. The converter has "11/04" written on it. That job was nowhere near as nasty as I was expecting! Probably due to the great write ups I found on here to do it.

The converter. The back hub that goes into the pilot busing isn't shaped the way I was expecting. But it makes sense given the way the inside of the pilot and crank is shaped. Anyone see any problem here?

I'll have the converter off to the shop this week.

Re: Torque converter causing vibration

Call me crazy, but i see a shining part on the converter that sits inside the crank, telling me its possiblly hitting the pilot bushing and causing it not to seat all the way or sitting uneven in the crank causing a vibration.
Why dont you just remove the pilot bushing ? If your going to replace the flywheel get a aftermarket one that is thicker, also have the flywheels check for balance.

Re: Torque converter causing vibration

Just wanted to update this thread.

I replaced the flex plate and torque converter. It did not effect this out of balance thing.
