Serious vibration

[J. Rogers]

I'm having trouble locating the problem. I've got a major vibration at all RPM's in all gears including park and neutral. The tranny recently received a rebuid. Prior to the rebuild there was no vibration of this kind. I suspect the flex palte is warped or out of balance, but is there any chance it's being caused by the torque converter?

[WINGO]

Crawl under your truck and see if the transmission mounts are attached to the cross frame.

If the flexplate was bent or warped you you hear a grinding noise. If the torque convertor was bad you probably wouldn't move at all. Was the torque convertor replaced when the transmission was worked on?

If a shop did the work, just bring it back.

I vote for the torque converter being bad. My bud "Cotton" a trans man from way back says if the vibration is felt in park, after reving the motor...its the T C......

just a thought, check your waterpump. see if it might move up and down.
