My right side went (Part number: 01008193) on my cub cadet z force 44(I think its the 04 model) and cannot seem to find a direct replacement online. I did find this one Ariens EZR 2 48 RIGHT HAND TRANSMISSSION Hydro Gear 311-24 R | eBay and it look IDENTICAL to mine. Contacted hydrogear and they said they are very similar but not interchangable and recommended a repair shop. I got a weird feeling that they might have been giving me bad intel so i take it to the shop?
