There isnt one, far as I can tell. I looked it up under the Montana and it says this:
Code:
1. Install the oil pan gasket (25).
2. Install the oil pan (24). Notice: Refer to Fastener Notice in Service Precautions.
3. Install the oil pan bolts (23). Tighten the oil pan bolts (23) to 14 Nm (10 ft. lbs.) .
4. Lower the vehicle. Notice: Do NOT overfill the transaxle. The overfilling of the transaxle causes foaming, loss of fluid, shift complaints, and possible damage to the transaxle.
5. Adjust the fluid level. Refer to the following information.
Transmission Fluid Checking Procedure
Fluid and Lubricant Recommendations.
Capacities - Approximate Fluid.
6. Inspect for fluid leaks.
Just do a cross pattern as best you can, it isnt too critical.
