Last minute questions

The first mod sounds like tossing the accumulator spring. A lot of the shift kits call for pitching this spring. The accumulator acts like a shock absorber for the system, so if you want to transmit the maximum amount of shock to your drivetrain, by all means chuck it. The second mod sounds like cranking up the line pressure. This mod sort of goes hand-in-hand with the blocked accumulator (since you no longer have the ability to store fluid under pressure, you just make more pressure). There are 2 drawbacks to this one. First when you raise the pressure, you increase the load on the pump. The pump is robust and can handle the load just fine, but it will take that much more power to operate the transmission, and make more heat. How much more power? Probably less than 5 hp at high RPM. The other drawback is the higher pressure would make any bind up during shift overlap worse. Trans-go does a pretty good job with shift timing, so this shouldnt be too big of an issue.

So here's my question; since you spent a lot of money for the engineering in this kit why would you not want to follow it's instructions? There is a phone # in the instructions, so why not "Ask Mr. Shift"? Call them and see what they say (and let us know for future reference).

If you just want to see how hard you can make the tranny bang, thump,and jerk around until something breaks, the $29.95 B&M kit would have done fine.
