    Default 2001 1500 HD Transmission Temp

    I bought a 2001 1500HD crew cab 4X4 about 6 months ago. The guy I bought it from said the transmission was rebuilt within the year I bought it but could not produce receipts. I live in Southeast Texas and as the temperature warmed up for summer my transmission started heating up. If I sit in idle for any length of time the transmission heats up (to about 190) and when I start driving again it shifts hard between all gears. Does any one know at what temperature the transmission should be operating? I have gotten mixed answers anywhere from 140 to 180. Would the rising temperature cause this problem? Also, has anyone installed aftermarket transmission coolers and have a recommended brand? Someone also recommended a deeper pan. Any recommendations? Thanks for your help.

    In the Owners Manual, it States the Normal Operating Transmission Temp. Range is Between....100 to 265 Degrees.......Below is a link where I installed an Aftermarket Transmission Cooler....and I also installed a Aftermarket Aluminum Finned Deep Transmission Pan.....Both Aftermarket Parts I've just mentioned have Helped Big Time!! with Reducing my Transmission Temperatures when Towing.
