OZ 4/4,
Replacing the entire chassis, on Morgan's dime, did the trick. It's a much stronger build. My build date was October of 2012. I suspect that the startup torque spikes are the culprit as one is going from zero to 100 ft-lbs in a very short burst. That motor wants out! I think mine lasted as long as it did as I have always kept the running RPMs at, or above, 3,000. Never let it lug or idle too long. That action also helps to preserve the so-called compensator, which is primarily designed to absorb the spikes and smooth it all out before it hits the transmission. The stock compensator, which was a Harley design lasted until 22,000 miles when it died. For the last 35,000 miles I've had the Centa unit with no problems. When we swapped out the the chassis, the dealer replaced the rubber cushions but they didn't really need it. Keeping the revs up really helps to smooth out the forces trying to destroy the car! Live and learn. This car has been nothing but a collection of learning experiences.
