Default The new problem

Just got my stall installed tonight and afterwards it seems that my car is vibrating to hell. In drive, neutral, park etc, it will vibrate roughly if you give it any gass, I noticed around 140kph it smoothens out, but I'm trying to figure if it's a sensor or vacuum leak or something else.. I need some suggestions.. Maybe something was pulled out when we moved the transmission.

Any ideas?

Sounds like something is out of balance. May need to double check the fly wheel and such and make sure they are balanced right.

The flywheel is attached to your motor... The crank doesnt stop spinning in neutral...

May be something as simple as a missing converter to flex plate bolt. Take it back and let them worry about it.

I bet they didn't seat the converter fully on the pump and didn't clearance/shim it to the flexplate, installed the flexplate backwards, didn't fill the converter with fluid, didn't tighten down the flexplate-to-converter bolts properly, or didn't use the correct hardware to fasten it to the flexplate.

One of those things, probably.

The converter was filled with fluid, the flexplate was stock, the hardware to fasten it was stock, the converted seemed seated... everything was done except shim it.
