I was out driving on the beach (lots of Beach Bunnies!) today. The air temp. was 89* and I was in deep loose sand. I put the truck into 4Hi, locked in 2nd. gear with the rear locker on. I know that deep loose sand can lead to over heating. I see it quite often down here from the snow birds. At any rate, the engine temp. never changed so I switched over to see what the tranny was doing. It was up to 208*. Hmmm, close to boiling! I shut off the AC and opened the windows and it dropped to 195*. Much better. But now I have fine sand inside my truck! I drove about 4 miles on the beach.

Tranny fluid doesn't boil at 212 like water.

i think you're fine...i've been in the same situation, my transmission hit 210. it went back to normal when i hit pavement...cheers

Good transmission fluid is good for 300-400 degrees C. according to this web site. That's about 700 degrees F. I think you were ok...

just curious....what temperature is considered 'normal'?

after its warmed up, it's running 190-195°

don't think the A/C has much to do with your tranny temp..

From the owner's manual:

"Transmission fluid temperature gauge:

If the gauge is in the:

Normal area: The transmission fluid is within the normal operating
temperature (between H and C).

Yellow area: The transmission fluid is higher than normal operating
temperature. This can be caused by special operation conditions (i.e.
snowplowing, towing or off-road use). Refer to Special operating
conditions in the scheduled maintenance information for instructions.
Operating the transmission for extended periods of time with the gauge
in the yellow area may cause internal transmission damage.
Altering the severity of the driving conditions is recommended to lower
the transmission temperature into the normal range.

Red area: The transmission fluid is overheating. Stop the vehicle to allow
the temperature to return to normal range.

If the gauge is operating in the yellow or red area, stop the vehicle and
verify the airflow is not restricted such as snow or debris blocking airflow
through the grill. If the gauge."

If I were you, I would check the transmission temperature gauge!

Thanks for the information guys. It looks like I was worried for no reason.
