Nv3500 vs ax15

I think you'd be happier with the gear spacings on the AX-15. The NV 3500 is going to have the gear splits only a truck could love.

Think you have that backwards
I put a NV3500 in my 93 318 Dakota with 3.55's that came to me with a smoked 46RH which itself got rebuilt and stuffed into my 92 Dakota

Higher gears are definitely required with the ax15. I was running 3.23’s in my Duster and still only using 1st gear if I was taking off on a hill. I’ve since installed 2.76’s and now use 1st through 5th gears as intended.

I had 3.07s in a wrangler with the AX15 and 5th was all but useless under 55 with a stick 4.0 inline 6 and 235 15 tires even more so with the 31/10.50s I had on it for a while.
I wouldn't worry about an OD trans with gears (numerically) lower than 3.21/3.23.

Yeah that’s not the case at all in a car with a 25.5-26” tire. Like I said in my last post, anything over 55-60mph, I use 5th. And around here, I’m using 5th every single time I drive the car. The gear splits with an ax15 and 2.76’s is nearly identical to a 904 with 4.10’s.
