Thank You. [Reply]   [No Email]

Mine does this (no F or R) often when the fluid is cold. I usually hold slight pressure on the lever while curling the front bucket. Usually goes in just before the engine wants to stall. No issue after it warms up. Check the linkage as it goes into the bell housing. Mine was held by a cross bolt but there was no slot in the arm to tighten it on the rod. Added a slot and it has been tight ever since. Just a guess. Jim [Reply]  [No Email]
