66RFE Sonnax Thermal Bypass Eliminator Kit
Has anyone installed or heard of success when using the Sonnax thermal bypass eliminator kit? It just looks to be a cartridge valve swap while retaining the OEM body. I have warranty for another 3 years and don’t want to install an ATS or REV if that’s what they’ll use as a reason to void it...- PowaaaWagoon

2002 4.7 with 545RFE and 4.56:1.00 trutrac = AWESOME!!!
Just wanted to share my experience thus far with owning and upgrading my Ram: I inherited a 2002 Ram from my Dad last year. It came with a 4.7, 45RFE (it was originally a 4 spd) and 3.55:1.00 gear with an open diff. The truck was a real pig. It was slow to get up to 65, got horrible fuel...- Johnny_N_TX
