02 7.3 turbo diesel tranny running hot

I have a 02 7.3L turbo diesel. I went to a mudhole and my transmission overheated and puked some out. I refilled the trans and drove 40miles home no overheating. I drove to Jacksonville from Orlando and the trans temp stayed just under the yellow and in the yellow. Same on the way home. I payed $260 to have the radiator and the transmission cooler removed and completely cleaned, the only code on the computer was trans over temp. I dropped the pan and changed filter and fluid(every thing smells fine and looks fine). still overheats but has gotten worse I can now only drive 20-30 minutes before heating up into the red and making me shut it down to cool off. Everything shifts fine and there is no slippage... I have heard that there is a thermostat control in the valve body of the trans? I've also heard from a local transmission guy that he thinks its the toque converter, because its not locking in completely and the only way for it to cool is if its locked in completely... Any answers???

Never heard of a Thermostat Control in the valve body. Have you ever replaced the external line filter.

What gauge are you using the factory one on the dash or an aftermarket one. Also check the vent tubes make sure they are not clogged with mud.

I've never replaced the external line filter, I was unaware there was one. I'm using the factory gauge. I'll check into the external line filter and the vent tubes though. Thanks! Anymore opinions would be great!!!

There is an external line filter...I just got my trans fluid flushed today but didn't know about another filter...where is it located and where do we buy a replacement.


My trans temp gauge ALWAYS reads in the middle when the motor is on...even the 1st second it cranks up after sitting all night so I am getting an aftermarket gauge as I don't see how I can trust the factory one.
