[dclassens]

Not positive , but a 48RE .

 

[Glen Pratt]

It's a 47re. I have one. The 47rh was in the 1994 and 1995 trucks.

48re was a late 03 intro

THANKS A TON for the feed back guys.

Can somebody give me a quick lesson on the 47re. Good, or bad. I dont haul very much ever(never over 5K) and simply would use it as a daily driver. I was thinking about simple power upgrades(tst kit, injectors).



General feedback would be great. Thanks!!

I towed over 11K RV for over 50K miles with my '98, of just over 100K miles total. At about 35K miles, I had a Banks Kit, a valve body and a couple of other add-ons put on, as well as an exhaust brake. I replaced the TC at about 90K because I thought I should have a beefier one, not because it was bad.



Towing 5K probably wouldn't put any undue strain on the 47RE but when you start adding power mods, all bets are off.

With added horse power you will need to at least upgrade torque convertor and maybe the valve body.

My '98 12v has logged quite a few miles pulling a decent size 5th wheel (about 10k lbs) and at 150k miles I threw in a set of Bosch 300 injectors (truck is stock otherwise) and at 163k the original untouched transmission is doing fine. It could use a better TC and shift kit to help the very inefficent stocker which I'll do when I have the bucks.

The good thing about the '98s is they have a deeper transmission pan than the older trucks. . . put a temp gauge on and service the trans on a regular basis, drive it sensibly and it should last. Another suggestion is to manually shift it so that it'll shift at a higher RPM, I think that'll buy some transmission life.

Is the RH stronger then the RE, just wondering because it seems no one offers a Billet output for the RH.

Actually. . The RH was also in some early 96 trucks as the switch over was not complete right at the start of the model year.

Is the RH stronger then the RE, just wondering because it seems no one offers a Billet output for the RH.

Not necessarily,however,since the RH is long gone from a manfacturing standpoint and the RE is still widely used ti only stands to reason why the parts for the RE are more readily available than the RH. I am not sure that way back when anyone even thought of billet for a RH... ..... Andy

The transmissions are not all that different. The difference is the VB and the governor. The RE tail shaft is shorter than the RH because the RH has a fly weight governor in the tail shaft housing. I think the rest of the internal parts are the same. One of them has a steel OD sun gear support part and the other has an aluminum part. I don't remember which one has the steel part. I think the RE.

Just as usual, The TDR puts forth tons of great info. I am getting that most people who spoke up would have no issues using a 98 as a daily driver. Simply use a little common sense with the auto trans and a guy should have no worries. Thanks again guys!!

Billet Output Shaft

Is the RH stronger then the RE, just wondering because it seems no one offers a Billet output for the RH.

Jim, When I was inquiring about transmission upgrades for my 47RH I was told by 2 different transmission shops that the OEM output shafts were very strong in fact so strong they have been and are still used in heavy race applications in other Dodge transmissions (I guess they are interchangable) .
