I drove it a little after lift and it had a slight vibe you could feel in your seat. The T/C drop took care of that, but what I was feeling now was more in the pedal. After doing some research, I took a small trip around town with Overdrive turned off and it made a big difference.. I think the vibes I was getting was due to engine lugging (more of a harmonic type of vibe) and tranny searching for what gear to be in due to running 31s.. For now on I will turn off overdrive before I put in gear and only use on Hwy. I still feel a slight vibe in pedal when I am sitting still in gear and barely give it gas. That as well feels like a harmonic type and goes away quickly as the RPMs go up.. I will check motor mounts, but I think it is the 6 and 42 combo that is main problem at low RPMs..
Thanks for the replys.
