You don't need to worry about the tranny temp. As long as the engine is up to temp then the tranny will be fine. It exchanges heat with the engine.Has there been anyone to install a transmission temp sending unit on the nag1 transmissions? I've tried to look a couple times on here as well as on the lx forums but it's kinda hard to find because there are so many thread on measuring the fluid level.
I'm looking because I wanted a cheap way to check my trans temp so i make sure it's up to temp before accelerating too hard.
Also, with a 3.5L, you are never going to stress the Nag 1 tranny.
