trans went out, which 1 to replace?

If it's a straight 10 with overdrive, it will be ok. A true 10 speed direct has no overdrive. A super 10 splits every other gear.

 

I have a super 10 myself in a 95 fld120

 

if there is any grease left in it take a sample to see if it was cooked in the fire. heat can weaken the hardness of the gears and make the o-rings brittle on the internal slave cylinders. if it got hot enough.

 

@heavyhaulerss, I guess what i'm trying to say is, there are 3 kinds of 10 speed transmissions:

1. 10 speed overdrive
2. 10 speed direct
3. Super 10

I think with your setup, which is similar to mine either 1 or 3 will work the best.

 

A Super 10 is based on the 9/13/18 case, a straight 10 is different, meaning the driveline may need modification. Go to Roadranger.com and look up specs to sure.

 

You're right. A 13 speed would fit also, with no driveline modifications, if one was available.

 

For driving heavy I liked a 13, may even increase your fuel mileage some since you split than shift so the RPM's stay in a range, but not a mechanical expert myself.
