2003-2007 Dodge Ram 2500/3500: Transmission Removal (48RE) 5.9L Cummins

Time: approx 2 hrs

Difficulty - moderate

Cost - appropriate tools


ATF+4 or equivalent

Drain and Fill - 4 qts (stock pan)

Total Capacity - 15 qts (capacity may vary depending on pan, lines, cooler, etc.)


Equipped with the 5.9L Cummins, the 48RE transmission in the Dodge RAM 2500 & 3500 pickup can be removed quite easily. The exhaust is out of the way, the rear cross member drops simply, and the torque converter bolts have ample access. The transfer case can be dropped with the transmission, or easily removed to save weight. 


Watch the video below to see the transmission removal on a 2006 Dodge RAM 2500. The process is the same for 2003-2007 Dodge RAM pickups with the 5.9L Cummins and the 48RE transmission.
