1. What do I need to do to recertify my Superglide Transmission case?

You must remove and send in your cleaned transmission case and liner to be inspected and recertified every 5 years. The charge is $75.00 plus shipping back to you and the process takes approximately one week. Send the transmission case with liner to:

2. How do I know if I need to recertify my case?
  1. If the date of manufacture on the side of the case on the date boss is 5 years older your case will need to be recertified. The date boss is found on the passenger side of the case, next to the S/N boss.
  2. If your case has been recertified in the past and the SFI numbers are 5 years or older it needs to be recertified.

3. How do I adjust the bolt on the back of my transmission case?

The adjustment bolt's purpose is to soften the shock on the tires when the transbrake is released. As the bolt is turned in (clockwise) it simply restricts the dump passage for the reverse piston. Slowing the fluid flow by restricting this passage during transbrake release "slips" the reverse clutches for a fraction of a second softening the transbrake release and slowing the reaction time.

There are a total of 7 complete turns worth of adjustment. If you bottom out the bolt and back it out 7 complete revolutions you will be at the wide open position (hardest release, quickest reaction time). This is where most racers run the adjustment. If you wish to try and soften the hit, start by turning the bolt in one complete revolution at a time until you get close, then fine tune from there. The "sweet spot" for the adjustment bolt when being used to soften the hit, is generally 4 to 6 turns in from wide open (1 to 3 turns out from fully closed). Up to .03 in reaction time can be changed by adjusting the bolt from wide open to fully closed.
