I have a CC 2140 that needs hydrostatic transmission work. The OEM price of $1100 plus labor for a replacement is prohibitive. I have not found anyone locally to repair mine at this time of the year and I do not have the knowledge or the manuals to do this. Anyone know of a used, rebuilt, remanufactured, or aftermarket replacement. I would be greatful. The numbers are: Tractor Model 135-232-100, Serial #295-453, other number on plate BO65G8; Decal on Transmission, Model #616-3080, Serial # 34-707
