I have an 88 LT230 that 2nd and 3rd are out on. I can get 1, 4,5 and R to work fine. I've noticed some issues that point to the one way bearing having possible issues such as coasting at idle instead of at proper RPM. I was wondering if anyone has any info on wether or not the one way could be at fault or if there are common issues with the 2nd and 3rd gear bearing, dwell, cam, etc in these.

Any ideas would be great. If I can avoid splitting the case I would like that, but probably will eventually.
