I just got my car back from the shop,they install my tilton package
and now my transmision is vibrating a lot specially when i exced
4000rpms.Beside that it works great ,is just a little bit hard to get the car going but it revs twice as fast and it doesn't slip at all
I just wanted to know if this vibration is a normal thing or should i have the shop look into it . thanks

 

It sounds like your transmission mount is loose.

 

When you bought your Tilton setup, did you buy the counterweight, it doesnt come with the kit from mazdatrix, and possibly racing beat, that is definately your problem if you didnt put it in.....

 

where does a counterweight for a clutch go on at?

 

It bolts to the back of the eccentric shaft. A stock flywheel has the counterweight integrated into the flywheel.
