Outer Limits 4x4 Board

I am considering doing an Auto swap on my disco. I believe I currently have the R380 gearbox ( it is a 1996 Disco).

- What are the gear ratios of the ZF ?
- Will my crawl ratio be better ?
- Will the ZF be able to handle more abuse than my R380 manual ?
- Will there is a be a lot of power loss...truck is mainly for off-roadinfg but i drive it to the trails and roads in Lebanon are hilly....
- Do most of you run manual or automatics....

I believe the truck will be easier to drive in the rocks that i d love doing.
I need more crawl ratio but my R&P is a 4.88 Toy R&P now. Rovers option are limtied my option is to go with the MD crawler gearset ( which is deam expensive compared to what you see available for Toy's or Jeeps) or the Ashcroft underdrive. I am afraid the 5.29 Toy R&P will be to weak to handle the 36" and the heavy disco adding to that that it will be roaring on the highway.
Searshing to see if anyone has adapted a Toyota doubler to the ZF...

Gday Jay,

I'd try the auto before getting crawler gears. The slip in the torque converter does a hell of a lot to negate the need for crawlers. The fellas that I drive a lot with have fitted cralwers to their manuals for offroading, though not so with the autos.

For the ZF auto swap what are the major things to watch out for in the SWAP.
