ZR51 Performance By Bill Boudreau - ZR-1 Net Registry Forums

dnobull · 10-11-2018

We Trailered our #180Z to Cave Creek Az just north of Phenox 1300 miles each way. Bill Boudreau is a former Aerospace Engineer & ZF Transmission Genius. The work he does to re manufacture the ZF Transmission is beyond anything done in the industry. When you get your car back you have the original transmission but it has been blueprinted by Bill's touch. He actually uses a micro hand grinder to touch the tips of every tooth in the transmission to shave off any imperfections. This is a very tedious process and takes several days to a week. The result is that he eliminates most sources of metal from ever being shaved off during shifts into the transmission oil. He matches all the springs for shifting so that those 3 gear shifts are never missed. The spring load allows you to just push the shifter from 2nd to 3rd with the palm of your hand to land perfectly in the 3rd gear slot.

I have many videos of his work if anyone wants to see the details.

The cost is more than you would pay for a new transmission but you get the best that can be had in a ZF 6speed transmission.
