How to tell difference between 47 and 48re?

[zstroken]

Dodge did not call it a 48 untill it had electric throttle controll, bit otherwise the transmissions in any common rail truck are all the same inside.

That is an incorrect statement. They made 48re without the tv motor.

My truck came with a 4 pinion OD planetary for some reason. I found out the hard way when I blew it apart. I bought it new in 04 so nobody had messed with it before me FWIW.

So basically I need a clutch kit for a 48re? Why do they even call it a 47re? becuase of the case?

A 47re and a 48re use different clutch packs, they will not interchange!!!

The 2 are definitely different internally. The numbers 7 & 8 in 47re and 48re refer to the torque rating of the trans. However I don't know what those differences are and yes there are 48re's without the TV motor.

Pump differences, Valve body differences, sun shell differences, etc, etc.
