transmission ID

[Archive]

I am soo new, this is my first post. I have only been a dodger for about 2 months now and am realizing that we have to do most of the service on these trucks ourselves. I bought my truck w/60,000 and a questionable service history so had to play catch-up. I bought a factory service manual first and then tried to ID the major components on the truck. The first obstacle was the transmission ID I need to adjust the bands properly. The body code plate uses the code "DGB" which has no reference in my manual. The "equipment identification" sticker under the hood says "DGB std duty 4spd trans" I was told it has to be a 47RE but the profile drawing in the service manual would indicate a 46RE. This difference in band adjustment is a full turn so I really need to know. I have searched the archives and have found nothing that would help yet. After reading this forum for 2 months now I know you guys will have the answer.

Need to know what year your truck is. As far as I know the 47 is used in the diesel and V10. The 46 is used in gasser V8 2500 and 3500 trucks. The 94 and 95 diesels have a 47RH and later trucks have a 47RE. RH = Rear wheel drive, Hydraulic control. RE = Rear wheel drive, Electronic control. There is a number on the transmission that can be used to make sure about that. Its on the driver's side on the flange that the pan attaches to. It may be obscured by dirt and grease but that's the number the parts guys need for some of the parts. The 47 also has a bulge in one side of the pan because the kick down piston is larger so the pan gasket is odd shaped. The 46 pan is more rectangular. I'm doing this from memory so if I have something fouled up here somebody please jump in.

Like Joe said the year will dictate which transmission you have but with the Diesel it will be either a RH or RE from 94 on up. Pete

Sorry Joe, I thought I set up a signature with that info but I don't see it. Anyway, it's a 98 25004x4 club cab w/tow pkg

Your's should be a 47RE. Just in case there has been some craziness in the maintenance check the transmission pan on the passenger's side to see if the side of the pan has a jog or is straight. It should have a slight job, that is, the most forward pan screw won't line up with the others on that side.

Joe;
It does have the slight jog you mentioned. The problem is the factory service manual showes a more radical difference in the 47RE profile, not only the pan but the converter housing as well. Was there several different variations?

Are you looking at some pictures in the manual? Some of them are exactly like the pictures in my '81 Imperial manual. They've been updateing this stuff for some time and a few of the pictures are a little off to say the least. Most are ok, but there are a few relics. If you have the jog in the pan it's a 47.

I have a 96 DC truck and it says the transmission type on the decal under the hood. Actually it is on the underside of it. Look up after you raise it. The same place has other info like gear ratio. Welcome to OUR FAMILY!!!ALOT OF INFO HERE AT THIS SITE FOR SURE... .

Welcome S Vincent,
Your truck has the 47RH. Read the service manual, especially the fuel system area. There is alot of info in the first pages of a given section.
As for band adjustment, don't do it! That is from the olden days when bands were thick and the wore rapidly. Due to advancements in hydraulic controls (and friction materials) they last longer and are much thinner. The small amount of adjustment you can make doesn't really matter as the bands are so thin on newer vehicles, if they need to be adjusted, they are probably worn out.
The best thing you can do for your trans is run Amsoil fluid. It lasts longer and withstands high temps. They reformulated it recently and it meets ATF +4 as well as Dextron and Mercon and all the others.
I used to adjust my bands but a very reputable transmission guy explained why its not necessary anymore.
Good luck and enjoy.
If you want to BOMB your truck (or tow a heavy load), you should consider increasing the trans durability first. Since you have the pan off anyway...
This can be done with some valve body mods at a very reasonable price if you do the work yourself.

Warning! This is the first step down a long slippery slope!

Your trans is a 47re no doubt. In my own opinion I would still adjust my bands as this will tell of potential problems. Have'nt found where synthetic oil is a must but to each their own.

Ride em hard and don't feel bad about putinn
them away wet!!!!
