Transmission temperature

[whttrk]

I am very new to this, so bear with me. My new 06 F250 with a 6.0 and Torqueshift has a block heater. When I start it in the morning without having used the heater, the trans temp gauge seems to rise faster than the engine temp, and when I have had the heater plugged it in, the quicker increase is even more dramatic. The trans temp is up in the operating range within a block of my driveway, while the engine still takes about a mile to hit the bottom of the operating range. Is this normal to have the trans warm up faster? Can wires to temp sensors have been crossed when assembled?
Other: Have 7300 miles on truck. Started a trip with a 5000 pound trailer with about 3200 miles, and MPG was about 11.5. Last fillup before getting back home at 7200 miles was about 12.5. A solo trip (no trailer in tow) of approximately 300 miles to Grand Canyon at 7000 feet while in Arizona was about 18.5 MPG at around 5000 mile mark. Trend is good and hoping for much better in bone stock condition.

Diesels are cooler running motors than gas motors, and the transmission has many working parts inside and tedns to warm up faster in general, especially when the coolant is not warm for the radiator cooler to cool it down. what you are seeing is normal......ive seen transmissions hit normal driving operating temps in warmer weather within 5 minutes of start up...the motor may take up to 15 minutes depending on how its driven....and also a trans is always spinning....a motor warms up slower at idle with no load....i woulndt be worried if i was you........Marc

Yeah it takes my engine quite a while to warm up if I haven't plugged it in overnight. Sometimes I can go several miles before it finally gets to operating temp...

Yeah I have the same truck and mine does the same thing. The trans temp will come up alot faster then the engine temp. Its normal I asked the tech. All the moving parts in the tranny.

I have addional questions regarding the transmission temperature in the Torqueshift. Is there a thermostat that controls the temperature? If you add one of those trans pans that add 2 gallons of fluid and has cooling fins, can you cause the temperature to be too low? Also, I read some somewhere complaint that the temp gauge will go up to normal, but does not read when the trans gets hot. That would make a gauge kind of useless. Is that true?

The first mods I did to my 04 was gauges, and exhaust system. Keith

I don't think you can get the trans fluid too cool. I think the torque shift has a problem with the tempsender in the trans. Preston

yeah i think the 5R110 torqueshift transmissions have a thermostat built in the trans that limits the amount of flow to the trans cooler. I was going to put an extra cooler on the trans, but I am afraid of the thermostat opening and closing all day long with the temp coming up then the cooler cooling it to the point where the thermostat closing the cooler. you know what i mean. but i have plenty of friends that have these transmissions and they never get hot. I am just adding the Mag hytec trans pan which just adds about 8 more quarts of fluid. My friends have actual aftermarket trans temp gauges and they never get over 165 degrees even on a hot day towing a trailer with about 6000 lbs on it.

My '02 F250 7.3's transmission temp goes from zero to mid range the moment the engine starts (it then sits there). Ford says this is normal but I have reservations about their philosiphy. What's true? Thanks!

No thats not correct unless you live in a very warm environment. Good time to get yourself a true trans temp gauge.
