So I have a 2002 Dodge Ram 2500 with a 5.9 24 valve cummins.
The stock transmission is a 47re.
I need to rebuild my tranny but I got the wrong rebuilding kit. The kit I got says its for a 48re. But I have a buddy with a 46re and its in amazing condition and he would sell it to me cheap.
So my main question is, can I put a 46re in place of my 47re?
Thanks in advance!

No, definitely not. 46RE was the small block trans behind the 318 & 360. Even if you could make it work in your truck, that diesel would blow it apart. Might be worth investigating if you can put a 48RE in place of your 47RE.

Thats kind of what I thought from research and what other people have told me. I just wanted to get another opinion. Looks like I am rebuilding the transmission. Thank you so much for your reply!

No problem. Check out ATS before you go with a stock rebuild.

You could upgrade your 47re to a 48re by changing the planetary gears. It might be cheaper to just rebuild what you have with some upgrades in various parts depending on how your engine is setup.
