Not sure if this belongs here but,, I have an issue with the transaxle not shifting smoothly between forward , neutral and reverse on an older MTD 136m667f118 14.5/38 rider,, I took apart the transaxle last nite and everything looks tight, no bearing play and packed with grease. My questions are: is there such a thing as too much grease, and it seems STICTION is playing a part on the shifter fork pulling the clutch collar off of the forward and reverse beveled gears. The grease is creating a suction and making it difficult for the sliding transfer to release.. Is there a method any of the members use to allow the clutch collar trasition smoothly between the two beveled gears?? Or should I clean and repack with some speacial non sticky but special lubracating grease???? Sorry if this is a repositioned post from new user area,
