Sonnax really nailed it with this kit."

The Performance Pack works like a dream."

Russ

The best working performance units we have done, and that's not from me, but my customers."

B. Bastedo
Advanced Transmission Care
Mooresville, N.C.

In a nutshell, I love it. It shifts exactly like I think it should. Not too hard, not too soft. Harder acceleration and the shifts firm up nicely."
