Hi A and all

Nothing about Your tranny capacity, but By Pass is waste of money in 
Your autotranny and pressure-case. Needed only when You close the 
throttle while shifting at full power with very high boost.

Why? Closing the throttle with max flow with no escape to the air means
that the compressor blades will loose their touch to the air and causes
surge, or when bad: stall. That means ( with other things ) slower acceleretion
to the c-wheel when You open the throttle again. 

By-pass can affect the mixture (fuel/air-ratio) feed for a while and is 
(in my opinion) not recommendable for the cat cars with mild ( lon-lasting ) 
upgrades.
