No Upshift or Wrong Gear Starts After Overhaul or Valve Body Service
Note
This applies to early model hydraulics only.
A complaint of no upshift or wrong gear starts after overhaul or valve body service may be caused by a mis-positioned T.C.C plug. The T.C.C. plug must be positioned as shown to keep governor oil and second gear oil separated.
