After evaluating all the options (about 100 times), I've decided to get the transmission upgrade done. I've decided to go with the ATS TripleLoc T/C, ATS Performance valve body, and ATS electronic controller. I will also be adding a Pacbrake and RV 275 injectors. I've driven the EZ Edge with 275's and that is exactly what I'm looking for towing. I'm going to Denver in July (through the smoke) and get the job done. After that, we will be heading to the Rockies, Yellowstone, and Glacier Nat Pk. I'm really looking forward to the upgrades and the vacation. Any advise on the National Parks and surrounding areas would be appreciated. Oo.
