Overheat transmission
96 Ford F150 Eddie Bauer with the Mazda transmission. The transmission and the floor boards get so hot you can't touch them. I went to Ford and to Midas, they both said it was catalytic converter. I had them replaced. The heat is still there. Any thoughts? Fuel regulator, valves, intake manifold, pressure regulator? Any thoughts I have no idea

If you try to touch the transmission in any vehicle after driving it for a while it's going to be very hot. Enough to burn you, I know from experience. And if you pull up the carpet and touch the metal floor right above the converter it's going to be pretty hot but not enough to burn you.
If the converter is sitting too close to the transmission and doesn't have a heat shield on it it can heat up that side of the trans pretty good. But you would most likely notice a leaking gasket if that was the case. It will cook the gasket before it does any damage to anything else. Also, if there's no heat shield on it it will get the floor of the cab hotter than normal but not hot enough to damage anything.
And as a for instance. In my 02 Mustang I have an aftermarket Tri Ax shifter and the Mach1 metal shift ****. There have been times during the summer where the heat from the trans will up the shifter and then heat up the metal shift **** enough that I can't keep my hand on it. But the trans is fine.
The only other thing you might check is to see if the engine is running too rich or lean. That can cause the converter to really heat up and can destroy the new converter. After driving it for a good while at night look up under the truck and see if the converter is glowing red.

He told me to take the truck back home unhook the battery, put back in the stock air filter system, then drive it around, then remove the battery again, then drive around and see if that will work. This did not work.
The temperature at the front cat is 200, the temperature at tranny is 130, the temperature at exhaust manifold is 210, the temperature of the floorboard inside cab is 135.
Not sure if these are normal temperatures or not.

Thanks. I have had this truck for 16 years and now all of a sudden I'm getting heart radiating from the floor board. I understand vehicles get hot, but I replaced a transmission in my car and after 30 minutes of running it straight I can work on the engine, touch the transmission while I'm working on the engine. My truck running it 30 minutes straight you can't even touch the transmission. My car is automatic, my truck is a manual. Manual transmissions should never get that.
