I've got an 02 ram 1500 slt 4x4 with some transmission issues.
First, what's the best way to know for sure which trans I've got?
Second, will a 46re from a 2wd work on my 4wd? I know I'd have to at the least swap the transfer case.
Thanks

 

Does your truck look like a 2nd gen body style, like the red one in the picture above, or the 3rd gen trucks? 2002 was 2nd gen still for 3/4 and 1 ton trucks, and a crossover year for 1/2 tons. If yours is a 2nd gen dodge, then you will have the 46re. They are electronically controlled and came out in 96 because of obdII. The 94 and 95 trucks have the 46rh, which is hydraulically controlled, because of obdI

Not sure on the 2wd and 4wd. I think you have to swap the tailshaft housing, which takes some work, but don't quote me on that.

 

Double check the year of your truck. Assuming its the 01, you would indeed have a 46re. Yes the tail housing can be swapped but you have to verify the overdrive clutch black clearance and use the correct spacer. Also if I remember ccorrectly there is a bracket on the outside that may have to be tweaked to work but nothing major. Biggest thing is that clearance between the apply piston and clutches.

 

Isn't the O/D section of the trans all one piece with the tailhousing? I seem to remember reading something about that..... if that is indeed the case, the 2 wheel drive trans will not work.

 

What is Obdl or whatever? It is the 3rd gen body style.

 

So I'm confused now. I have an 02 but with the 3rd gen body style. According to wiki, the 2nd gen can have the 46rh-re, it doesn't show a 46re as even an option. And on the 3rd gen it goes from 45rfe to 48rfe, no 46 anywhere. So, how the hell do I figure out which trans I've even got?

 

Take your vin number to dealer parts dept and get the free build sheet for your truck.
Tells you everything that came on your truck including what trans.

02 1500 is 3rd gen so in that case your in the wrong forum.

 

Some of the first early year 3rd gens had the magnum motors, and the 46RE transmissions. At least, thats what I have been led to understand. So far as I know, the newer transmissions won't even bolt to the 5.2/5.9 magnum motors.....

 

I realize that, my apologies. But it just so happens that my 3rd gen has the same trans as the 2nd gen. So really my question could be answered here. But I'll gladly take my inquiries to the appropriate forum if that'll make you feel better.
