Since you don't have the special dip stick need to check the fluid you'll need to go to the dealer. You can remove the dip stick cap but with no dip stick you may have a hard time telling if the fluid is burnt or not (it probably is). It also takes a special procedure (relating to temperature) to fill them correctly.
Over heating and burnt fluid is associated with the following causes:
EFFECTS OF INCORRECT FLUID LEVEL
A low fluid level allows the pump to take in air along with the fluid. Air in the fluid will cause fluid pressures to be low and develop slower than normal. If the transmission is overfilled, the gears churn the fluid into foam. This aerates the fluid and causing the same conditions occurring with a low level. In either case, air bubbles cause fluid overheating, oxidation, and varnish buildup which interferes with valve and clutch operation. Foaming also causes fluid expansion which can result in fluid overflow from the transmission vent or fill tube. Fluid overflow can easily be mistaken for a leak if inspection is not careful.
CAUSES OF BURNT FLUID
Burnt, discolored fluid is a result of overheating which has three primary causes.
- Internal clutch slippage, usually caused by low line pressure, inadequate clutch apply pressure, or clutch seal failure.
- A result of restricted fluid flow through the main and/or auxiliary cooler. This condition is usually the result of a faulty or damaged oil cooler, or severe restrictions in the coolers and lines caused by debris or kinked lines.
- Heavy duty operation with a vehicle not properly equipped for this type of operation. Trailer towing or similar high load operation will overheat the transmission fluid if the vehicle is improperly equipped. Such vehicles should have an auxiliary transmission fluid cooler, a heavy duty cooling system, and the engine/axle ratio combination needed to handle heavy loads.
The following is included only so that you know what the dealer will be doing. I hope that you are still under warranty, if not you may want to just have them change your fluid. Good luck and THANKS for serving OUR COUNTRY!!!
CHECK OIL LEVEL
1. Verify that the vehicle is parked on a level surface.
2. Remove the dipstick tube cap.
WARNING: There is a risk of accident from vehicle starting off by itself when engine is running. There is a risk of injury from contusions and burns if you insert your hands into the engine when it is started or when it is running. Secure vehicle to prevent it from moving off by itself. Wear properly fastened and close-fitting work clothes. Do not touch hot or rotating parts.
3. Actuate the service brake. Start engine and let it run at idle speed in selector lever position "P".
4. Shift through the transmission modes several times with the vehicle stationary and the engine idling.
5. Warm up the transmission, wait at least 2 minutes and check the oil level with the engine running. Push the Oil Dipstick 9336 into transmission fill tube until the dipstick tip contacts the oil pan and pull out again, read off oil level, repeat if necessary.
NOTE: The dipstick will protrude from the fill tube when installed.
6. Check transmission oil temperature using the appropriate scan tool.
7. The transmission Oil Dipstick 9336 has indicator marks every 10 mm. Determine the height of the oil level on the dipstick and using the height, the transmission temperature, and the Transmission Fluid Graph, determine if the transmission oil level is correct.
8. Add or remove oil as necessary and recheck the oil level.
9. Once the oil level is correct, install the dipstick tube cap.
