tranny problem brewing on my Harley F150.. 2000 with 92K miles. On the shifting sequece from 2 to 3rd it sometimes fails to engage and the engine races. Once coming off accel or just coasting it drops in. No other signs of slipping. Fluid is ok ( changed at 60K). This happened once before over 10K miles ago and went away. Is there a module sensing unit or vac pump going or what??
