what do you check first... changed intake on car,don't know if it's related. put a new 3200vig t.c. in and thinking this was the trouble, give it a 120deg. turn, but vibe is still there.thinking it started after trans. was rebuilt and t.c. installed.any help please and thks. as vibe is bad.

 

I think it may be due to the decreased weight of the smaller aftermarket converters. After installing a Yank, I have a very slight vib at around 1,200-1,600 revs. Seems to be slightly worse when the engine is just cold started.

It's not bad, but is nevertheless, slightly noticable.

Ron,

 

You may have a broken trans mount.
