See when you start to upgrade or build the transmission. Your gonna change pretty much everything to get the best performance. When you start to jack up the shift pressure, your gonna notice your shift change and the computer will think. Ol something is wrong and itll throw a code and it'll lock it in that gear just because your upgrading to bigger and better stuff. And the computer in the truck doesnt relize that. If you put that box on it. itll trip the computer to think its stock prssure! Even tho, you turned the pressure up 2lbs or whatever. But my $0.02 is, you cant go wrong with it so why not?

Some Rams built between 9-95 to 4-96 have computer programming that does not permit this lockup feature to work with a lockup switch. Dodge dealers have the ability to re-flash the computer to a newer program which prevents hunting among 3rd, 4th and lockup, and allows this added lockup switch to function. Dealers may charge you for this re-flash service.


DO THIS or you will be buying a new torque converter SOON. my dealer charged me $45 to re-flash mine. but that was ~6 years ago

when you lock the converter and it stays locked when you turn the switch off.

that means you need the flash. it happened to my truck when i did the switch.
