Towing with a j10

Ive had my j10 now for a few weeks and still havent drove it. Im waiting to seal my garage floor before I put a new clutch in the truck. Im wondering what would be the best set up for towing a fairly heavy bassboat? Its got a t18 but Im not sure of the first gear ratio yet. Ive got two other t18's that I have used in my cj, so I know the pros and cons of them. Bulldog gear is great, towing a boat uphill 3rd-4th not so great. I can always use low range on the boat ramp if need be so what other tranny choices are there? I know a scout t19 will bolt up to my xcase but what about the bell housing? What about a car tranny, maybe an early 70's 4 speed, can they even be adapted to a xcase?

you should also consider what gear ratios you have in your axles. if you have 4.10's or even 3.73's you should be ok no matter which tranny you have.
the tranny is only one part of the equation. engine tq and hp, tire size, diff gears all factor into the pulling power you have in your truck.

I've towed my boat with my cj and it does ok, but hills are different. I've got a 401, 4 barrel and 4.10 gears and going from forth to third is a big jump in speed and rpm's. Its almost like I'd like to have an extra gear between third and forth when towing.

I've towed FSJs with my Comanche (4.0L/AW4/3.73 with 33" tires) but only on dry pavement and with weight in the back.

Might try driving it before making a decision........

I know, I know, but would almost bet its got 4.10 gears. If it does then shouldnt pull the boat the same as my cj? My uncle had a suburban with a 350, 4 speed bulldog, never knew the gear ratio. It was the same way when he pulled his boat. I can "manage" pulling with it Im sure I was just wondering about other set ups and how people liked them.

It's not difficult to determine what your gear ratio is.

You didn't say what engine the J10 or the CJ have so we have no way to tell if it will tow like the CJ does.

The j10 has a 360. I'll check the gear ratio this weekend when I finally get the truck in my garage to put a new clutch in it.
