Ok so one of the transmissions needs a center section and I have to assemble it the left side transmission is tore up as you can see the keyed piece on the input shaft near the charge pump sheared off the input shaft and chewed up the machined pieces of the main housing near the the charge pump is this worth fixing will I have to get a new transmission or replace the main left housing and the input shaft also where can I find zt2800 hydrogear transmissions for parts
