The new OD command with the manual valve works well for guys using shift noids or racers that want to bang the shifter for all shifts including overdrive.

I believe the main concept for the new billet SunCoast VB is to create a race-specific VB that is super reliable, and addresses some of the current issues the big power racers are facing: torque converter control during spoolup, weird pressure drop issues, inconsistent performance as fluid temp/VB temp changes, etc.

The real problem with current FMVB setups using a factory casting is there are over 300 individual parts and pieces in a factory VB with numerous places for fluid bleeds, cross over, sticking valves, etc. With that many moving parts, it's amazing they work as well as they do. Most of the other drag racing specific transmissions have "race-only" simplified "billet" VB's with the minimum amount of moving parts, it's time for the A618 (47re/48re) to get it's own billet VB.


What other vendor's besides cope and suncoast?
