When I rebuilt my 915 I took the disassembled transmission to a friend who owned a shop and (years ago) raced IMSA. He guided me through which components to replace, which included the expected wear items but also two specific bearings on the pinion shaft (999-052-043-00 cylindrical roller bearing and 999-110-146-01 four-point bearing). Per Kevin's point, he didn't attempt to inspect these and I don't remember why he singled these out, but he knew the transmission had been club raced and would continue to be used on track. So, maybe it was a preemptive measure, given the high loading on these bearings. I also installed the Wevo one-piece bearing retainer plate.
