When does the rear clutch slip in reverse?
If the transmission does not slip in Reverse, the rear clutch is slipping. If slippage occurs during the 3-4 shift or only in fourth gear, the overdrive clutch is slipping.
Where is the overrunning clutch applied in a 47RE?
The rear clutch is applied in all forward ranges (D, 2, 1). The overrunning clutch is applied in first gear (D, 2 and 1 ranges) only. The rear band is applied in 1 and R range only. The overdrive clutch is applied only in fourth gear.
What happens when the overdrive clutch fails?
If slippage occurs during the 3-4 shift or only in fourth gear, the overdrive clutch is slipping. Similarly, if the direct clutch were to fail, the transmission would lose both reverse gear and overrun braking in 2 position (manual second gear).
What causes the clutch to walk out of engagement?
Slipout in the auxiliary section may be caused by the clutching teeth being worn, tapered, or not fully engaged. These conditions cause the clutch gear to “walk” out of engagement as the gears turn.

Is there a heater on my 99 Montana?
On my sons 99 montana, no heat control. a/c, air flow, etc. works great but no heat… any suggestions would be greatly appreciated. daughter in-law and 4 grand kids are gonna freeze to death this winter.
