Can anyone explain the difference between the automatic transmissions--the 47 RH & 47 RE? I have a 95 4x4/3/4 ton with the RH letters. I will be pulling a boat and trailer that weighs 5000# will it do the job, I assume it will as it has a tow package and the manufacture would not put in a tranny that would not live up to the tow package option.---Thanks, Ray

 

4 = 4 forward speeds
7 = strength of trans. (1-9, higher number, stronger trans.)
R = Rear wheel drive
H = Hydraulic controlled

The 47RH is Hydraulic controlled and was used in the 2500 and 3500 trucks from 94 to 97 that were powered with the V-10 and Diesel engines.

The 47RE is Electronic controlled and was used in the 2500 and 3500 trucks from 98 to 03 that were powered with the V-10 and Diesel engines.

The 48RE started in 03. I think 2003 models can be found with either model trans (47RE / 48RE) depending on build date and engine package (Standard Output or High Output).

I think this information is correct, Hopefully some other folks will chime in here.

 

Thanks Rattlin' it clears up some of the mystery that lies within these Ram Diesels. So far the transmission is working fine. I know or should say been informed by this site that the tranny is usually the weakest link in the drive train in these units. I've got 105,000 miles on it and so far so good. I will be having the tranny serviced next month as a normal routine service procedure.
Thanks again-Ray

 

Actually the 96's had the RE. My Dad has one.
