1979 aotomatic trans with a high/low range

I have a 1979 CJ7 with a V8 engine and a automatic trans that has a high/low selector gear. I would like to remove the high/low gear box. What does this entail? My jeep has never been off the blacktop and I do not need the extra gears. Any help will be nice!

You will need to find the drive coupler that is in the quadratrac transfercase without the low range box, snap ring to hold the drive coupler on and the rear cover. The low range unit will unbolt from the back the transfercase and the drive coupler can be installed with the snap ring to hold it in place, then put the cover on. Your best option might be to find a complete extra quadratrac that doesn't have low range as I am not sure how available the parts to remove the low rang box are.

After you pull off the low range unit

Hey thanks. I now know how to proceed. Think maybe I will gather the parts before I start. Is there any value to the gear box after I remove it?

Personally, I would leave the range box on the t case. It doesn't weigh anything and will add to the value of the Jeep when you decide to sell it.

If you are bent on getting rid of it and/or are looking for the parts to remove it, you may want to post in the CJ section.
