Sonnax Shift Enhancer = $45 Well Spent!

[daboostcreep]

I bought a Sonnax shift kit from DFuser.com and installed it today. Its a simple install requiring 8mm and 10mm sockets, and thin needle nose pliers. Install took about 1.25 hours including the time to drain, and refill the transmission. After doing it once, it can be done in about 30 minutes. It really firmed up the shifts. It doesnt slam, it simply shifts into gear more firmly, and instead of feeling like it kinda drops after it shifts, you feel a push from behind as the power is transferred into the next gear. A great $45 shipped, and 20 dollars in ATF! If anyone has questions feel free to post so I can help you.

The shift kit will also increase line pressure to help keep the clutches from sliping I did the John Wood valve body what a big deff that made shifts alot better now and doesnt take 10 years to get to the next gear as it did before in a higher tune
