Hello everyone!
I picked up a sm465 from a guy a while back and he claims that the transmission has been rebuilt a couple years ago and never put into a truck. After i put it into my truck and drove it i found that you can go from 1st (or low) to 2nd just fine and 3-4 are good as well but downshifting from any other gear into 2nd is actually impossible. There is no grinding when trying to put it in gear while moving it just won't drop into 2nd. Now after a while the transmission sounds like there is gravel in the bearings or something when it is in 2nd while driving. The transmission has also developed a loud rock crushing sound at idle with the clutch not pressed in. Has anyone had this issue or seen it before?
Thank you for your time.
