No Troubleshooting complete. Find cause for loss of oil.

Yes

Check for broken universal joint or drive shaft and repair as required. Is there still a problem?

No Troubleshooting complete.

Yes

Check to see if drive shaft turns with transmission directional control lever (FNR) in forward or reverse and rear wheels off the ground. Does the drive shaft turn?

No Check electrical connections at transmission. Is there power to the clutch solenoids?
