David P Posted November 28, 2016 Share Posted November 28, 2016 Accumulators work like suspension with springs and dampers, raising the dampening and balancing the springs, fine tunes the transmission giving slicker gear-changes. After experimenting with my own Hybrid transmission to find the optimum shimming, I have now also done this many times for others and this modification works just as well on stock GTE transmissions. This tried & time-tested modification, increases gear-change speeds without skipping traction and reduces clutch-plates friction which in turn reduces heat. Every little helps. Feedback Here If there are any more out there that I have forgotten to add to the list, please remind me and I'll update. I am often asked if these faster gear-changes make a Supra faster? To answer this question with minimal old wives ambiguities, I have pm'd all present users requesting any "official" before and after times?

David P Posted August 11, 2017 Author Share Posted August 11, 2017 It would be really useful information; for shimmed-box users to respond and report any quarter-mile time-difference after this gear-shift speed upgrade? Thank you. Link to comment Share on other sites More sharing options...
