Hot trans? Tranny Tom?? Diesel 4R100 Superduty
I "think" my transmission (4R100) in my 02 7.3 Superduty is running hot. Here's a light background on it.
Truck has 145k, transmission is stock, never had any issues with it until this winter when the factory trans cooler broke. I ran low on fluid a time or 2 but dont believe any damage was done as it still shifts like normal and the temp during this winter never got above 170. I finally replaced the broken cooler with a much larger Ford 6.0 trans cooler and refilled the trans.
I drove my truck from White lake to Milford and then back yesterday and was nearing 170. I have an aftermarket trans temp gauge that has always been reliable. Is this cause for alarm? I havent noticed any slipping or weak shifts since installing the new cooler. Could i have fucked something up, not enough fluid ... or are things working as they should. What should be a normal operating temp for a transmission? I think i read normally 100ish degrees over outside air temp. I just want to make sure I dont smoke a $2000 trans.
I'm the man in White.
