    48re delayed shift into gear and sometimes won't at all. 10k on recent rebuild. Was acting up previously, adjusted bands with new filter and fluid 1k miles ago, was shifting fine until it left me stranded at the fuel island. Any ideas? I'll share a link to a video I had to upload to YouTube cuz...

    Symptom: High RPMs (~3500) to shift gears while driving Vehicle: 3rd Gen. 2004 Dodge Ram 2500 with 5.9 Cummins & 48RE Automatic Trans (OEM) Story: Found out that it actually means there was no 2nd gear and it was just shifting from 1st-3rd. I had upgraded the governor and housing to the GM...

    I have a 2005 2500 with a 48re. I bought the truck with what looks like a fully built transmission but I don’t have paperwork on it. Sometimes when I go in reverse the truck will bog down and gain a lot of tension like the torque converter in starting to lock up. When I put it back into neutral...

    I’ve been leaking tranny fluid for a while and couldn’t find the issue but I think I’ve figured it out. It looks like it leaking out of this 90° boot. A buddy had the same issue but he said he was leaking out of the hard line labeled 1 in this picture. Those lines are going to the heat exchanger...

    I'm in the process of building my 48RE to handle more power. I bought the Transgo TRFE-PRO shift kit and was wondering if the upgraded transducer and solenoid kits I see are actually worth the cost? My VB currently has pretty much brand new electronics as it was replaced about 6 months ago and...

    I have an 06 with the 48re 4x4 with 167k miles on it, nothing done performance wise to the engine just an intake and cat back pipe pretty much, transmission slips sometimes, recently it started making this very high pitched knocking/ticking sound and has gotten progressively louder, the shift...
