Ive got a 2005 4x4 with the automatic, Im not a fabricator, what Im looking for is something that will allow the auto tranny to lock up sooner, go through the gears quicker, I drive the truck unloaded, like a grandma, after towing a 10,000 lb landscape trailer with 3 tons of grass clippings in an isuzu NPR with 250 ft lbs of torque, 600 ft lbs is serious power in an unloaded pickup, so my question is, does anyone know of a way of getting the tranny to go through the gears any quicker?

thanks

 

The problem is not the shift points, its the sloppy converter and programming to save it. I think you would be quite happy with a good converter and a matching VB. Give Dave Goerand a call at GB Transmissions and tell him what you want. It sounds like he has figured out the shift timing and issues with electronics.
