Unless you have something trick, the 4T60, and the 125 have a 3.33 diff ratio, and the 4T40 has a 3.27 ratio. The best sprockets were 32 drive and 38 driven for all three units. What ratio do you think you have for the 125?

My friend, I told you months ago I would help you with this project.
I also asked you to not put it out there "live", and I told you why.

Russ, He's all yours now, buddy..

This problem of gear ratio is why there are not more front wheel drive cars running out there. There just is not enough gear ratio in these transmissions, so as a Band-Aid they try and make up for it with short tires. So now you have a problem with consistent traction !
