Is this a worthwhile investment for the 3-Mode Automatic Transmission ECU Upgrade by Jim Wolf Technology?? I mean playing aroung with the auto trannies are delicate enough for performance tweaks. I know there is another Auto trannie upgrade similare to JWT. I forgot the name, but my question is which one is the safest and best application for a 95 maxima auto.????

 

Turbo95Max has a JWT tranny module for sale if you're interested. E-mail him for details.
