Drive Train Vibration/Shaking

[got2b240]

After Pulling hard on my newly SR powered 89 240sx Fastback for the last couple of weeks, I have noticed that my car shakes or vibrates when I slow down or when I take off slow. Sometimes it happens even when I am driving on the highway, but after a while it goes away. Its really annoying, and I noticed that my shifter vibrates with it? I have searched and couldnt find anything in relation.

Any help would be greatly appreciated.

does it seem like you are feeling vibration from a rough running condition? how about a dead cylinder?

[got2b240]

i hope not, the car seems to idle verry smoothly, and last time I did compression i got 150 across the board no lie. I am stumped, but I think this started happening after me and my cuz did the rear brake pads, maybe we put them on wrong and warped the rotor's?

have you checked the motor and transmission mounts? also is the transmission cross member tightened down?

good point 180 fan, i think i might need to get new transmission mount and motor mounts. thank you
