Recently, we just pulled the gearbox out of one of our CRX's because of a noise that we initally thought was a bearing issue. This gearbox featured a 4.73 FD and an OPM LSD for 3 years of ITA racing also including the now famous Targa Newfoundland Rally last September. We found that the FD pinion gear had several teeth "splintered" and the ring gear was fine. The OPM unit was showing wear as well. This gearbox has had synthetic fluids (changed every season). The manufacturer of the FD recommended just factory 10W40 fluids and indicated that the syncros don't like synthetic fluids, however we didn't have any problems with the syncros.

The box didn't have any noises until after the Targa Rally. For those that don't know about that rally - it consists of 1600 miles of high speed tarmac rally featuring some very long stages.

Has anyone ever seen this happen and/or have any similiar issues?
