[mv7fd]

how hot should my automatic trans get when just driving around. it's an 02. also when i came out to my truck after 8 hours of sitting i started the truck and the stock trans temp gauge needle moved i thought it would have been cool not really sure if its right or wrong

I've just been through the same thing. Truck sits all night and fire it up next morning and the gauge goes to normal. The factory gauge is (like all say) just an idiot light with a needle. For true reading install an aftermarket gauge like Autometer or any other brand. Real easy to do.

A glorified dummy gauge....

Both the OEM trans temp and oil pressure dash gauges are absolutely useless, once you put in real gauges you will realize just how useless the OEM ones really are. Which to me is shocking!!

Eh, doesn't totally shock me. Most users of these trucks have no idea what temp the 4r100 are supposed to run at so they to dumb down the truck so they are not getting a million "My trans gauge is moving what do I do?!!" service calls.

People can be so dense when it comes to cars, I worked at an Acura dealership during college and a lady with a TSX called up and said "My battery is dead and my purse is in my car but the remote won't work...what do I do?" My response...'Hmm...use the key.' So if the basic functions of a car door can confuse people...how are they supposed to understand the operating conditions of a transmission with a few hundred working parts.

In High School, I worked at a BMW dealership and I had a guy bring his car in claiming it had no oil pressure when cold...made no sense. Finally I sat in the car with him and he pointed at the dash and said 'Look it has pressure now but if you start it in a few hours it will have none!' My response...'Sir, that is the water temp gauge.' And it is clearly labeled as such.
