signs of a bad torque converter

[tomc983]

i put the truck in gear an i have a vibration through the truck could it be torque converter?

Could be anything.

Could be anything.

x2 could very well be an exhaust rattle...

Doubtful. Exhaust would cause a rattle, not send vibrations through your truck.

come take a ride in my truck

Again, buddy is talking about a vibration, not a repeated knocking which is what your describing-which would be caused by poorly installed exhaust knocking on the body/frame of the truck. Vibrations are harmonic.

 

[tomc983]

i started with exhaust but didnt solve the problem and like LBZ said Vibrations are harmonic witch is what i have im dreading it but may have to go to the dealer on this one

Flexplate cracked?

Bullshit.

If the exhaust is bouncing off the truck it will knock/rattle. If it's pressed against the truck and not bouncing, it will vibrate like a SOB. Think of it like replacing all the rubber isolation pads, with solid mounts.

Wanna come take a ride in my BURB, she's sure got some exhaust vibrations to her that can be pretty bad at times if you lkoad it just right. Many times a combination of things can cause some wicked vibrations, but no one thing can be pin pointed. A good example was when I had my 6.5 and a gear vendors installed in it. I would get a WICKED vibration that would take the rear view mirror down, but everything in the driveline was fine. It ended up being the driveshaft matched harmonics with the exhaust at OD from 45-60, and man was it WICKED when they matched. Kick it into neutral and it went away. Ended up taking the GEAR VENDORS out since I couldn't tune the harmonics out.

I stand by my statement. The only way a knocking exhaust will simulate a rotating vibration is if was really really quick oscillation back and forth. And I mean REALLY fast like an exhasut drone from the gasses or something.

With some transmissions you can remove the converter bolts, push the converter back, and run the engine to check for vibrations. Don't know if you can do that with the Allsion! :cool2:

Just make sure your down pipe is against your up pipes or headers and you will get some good vibrations not any rattles or knocks.

on the allsion you have to pull the stater to get the converter bolts off

 

[tomc983]

so really the only way i can check it is pull the trans

Well an easy check would be to get a 36mm socket and rachet to check the harmonic balancer bolt.

ill try it thanks bud:hello:
