transmission compatability
I have seen some conflicting information here in other threads. I have a V6, 2wd 2001 auto with what I am told has a 42re transmission. My forward clutch packs & 1st gear band are crapping out on me. I had 3 area tranny shops tell me the same thing with no coaching from me, so I suspect they are correct. I went to a 4th tranny shop that said something very confusing to me. He said he has a used 518 that he can swap it out with & those are a better transmission. I know the 3.9 is the same as a 5.2 only with 2 cylinders lopped off, so I imagine any tranny made for the 318 from the gen2's will work? Are the 42 re & the 518 trannies swappable like this? If it is done, are there special parts I would need to get or other modification required? Would it confuse the computer or make my speedo incorrect? I really hope you guys can answer this for me, because I cant afford the rebuild but I think I can afford a junker tranny and I would love for it to be something stronger than the one I have that started crapping out at 42k miles.

IF the 46RE is also the 518 it's an OK transmission, they break and need repair but, what transmission doesn't? sometimes a full out rebuild, sometimes not.
I don't know if it's a better transmission then the 42re, I have the 46RE in my truck, it was rebuilt about 4k before I bought it, problem free so far. I did do a fluid/filter change after I bottomed out and bent the transmission fluid pan a little.

I noticed that ALL the guys who work at area tranny shops drive ram trucks. I also hear from various sources that dodge makes crap for transmissions. I also heard that from local tranny shops. I understand what you mean about anything can break. If it has moving parts, it will need work eventually. I just think there is some credence to what I hear about dodge trannies since mine is crapping out at 42k miles. I have also been looking onto finding an adapter for a 700r4 gm tranny also, but not for the dodges. Those are known to be very stout trannies and with a small amount of upgrading, can handle tons of abuse & power. I hope someone out here can tell me for sure if they are the same or different.

Looks like 46re will work on a 6 cyl, but I do not know the difference between 518 and 46re labeling....
