I got a rebuilt tranny from t&m trans exchange out in california for about $1000 including shipping. I wanted a marlin HD, but the lead time was around 6-8 weeks at that time (1.5 years ago). I've heard they now have them ready to roll though. Been very happy with my T&M so far.

Mine started with noise in 4th and later 2nd and soon after that I lost 4th and 2nd. I know some people go years with noises, but it was only about a month (~500mi) between noise and destruction in my case. Had to drive her with 3 gears for 5 hours through the mountains to my buddy's shop to do the replacement and the clutch started letting go 1/2way through the trip.
