    Throttle body cleaning major improvements with shifting 09-12

    For all my ppl with the OG charger lookin 1500s around 09-12 with 5/6 speed. I know newer ones come with em but Canbus is just different(not so smart). My truck would clunk into gear sometimes, sometimes hold first a little longer ,surge (idle,drive,AC idle) , inconsistent power band...

    Manual swap

    I have an 03 dodge 2500 with a 5.7 hemi that I am redoing from the ground up, I am putting a bigger cam in, porting the heads, and getting a new intake along with bigger injectors fuel pump etc. I am positive that my 545rfe will not last long with my final power numbers and I know it is out of...

    No 4th gear on 545rfe?

    Just finished doing a valve spring on my 04 5.7 and I went to test drive it and it won’t give me 4th. I think it’s due for a fluid change and that might be it but I don’t wanna ignore other more serious possibilities

    Tow/Haul mode... AND... On Demand Shifting 545RFE?

    I have a 2004 Ram 2500 with the hemi 5.7. I recently towed a ~5000lb trailer about 1k miles. Two questions: 1. What does the Tow/Haul mode button actually do? I thought at first it was turning the OD off, but when on the flats it still seemed to be shifting into 5th gear. The only...

    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...

    Chasing down transmission faults... 2006 545RFE

    2006 5.7L Hemi with a 545RFE transmission. Had the truck since 2010, and have had the tranny rebuilt twice in the past ten years. Recently, I've been having issues with the TFPS throwing the truck into limp mode when I am accelerating up a hill. Seems to happen only at high speeds and when the...

    Transmission relearn for new 545rfe??

    Does anyone know how to do a transmission relearn or quick learn for the 545rfe? Or have you guys just thrown a new one in and driven without worrying about doing a relearn? I am replacing my transmission this weekend in my 2010 ram 2500 5.7 since the stock is shot. The trans I got is a...

    545RFE Transmission going out. What route to take? Experiences?

    I threw a check engine light, checked the code on the truck. The code I got was p0933, transmission hydraulic low pressure sensor. Truck was driving fine still. So I took it to the dealer, typically I do everything myself, but I was on a time crunch and am driving 1600 miles over the next few...

    HD Guys, Is The 66RFE A Good Transmission Unlike The 65/545/45??

    Reason I'm asking is because if I do a trans swap in my 3rd gen as a part of a performance build, I WANT a TRUE 6-speed with decent ratios and the ability to hold some good power. From all of my reading and deductions thereof, a 66RFE seems like a good choice. Good gear spread, true 6 speed...
