727 to manual question

just a idea i am toying with at the moment since my tranny is going to be out of the jeep anyways and my dad brought it up what all would it take to convert to manual like 435 or similar? I do like the auto we do alot of climbing long steap slops and there tend to be mini ponds scattered through out the middle of our trails here year round so the auto is nice for chewing through it but i really dont want to have to worry about chewing through another trans

Tf 727 is a strong Trans With a rebuild and a good cooler you wont kill it for a long Time

But if you doing a swap you'll need the clutch pedel and Lever assembly and possable different Driveshafts depend on what case your use a flywheel for you engines and a Trans

Well if you take the trans out see what some local shops will do a bench rebuild for then price up a trans swap and see which ones cheaper

I was just looking for a way to be lazy and put a lighter tranny back in lol
actually just thought the info would be good to know in general. Has anyone actually swapping in a manual in place of a auto?

there is a lot of good info on here about swapping. Search for a Ax-15 swap. Should come up with some info. I'm in the process of the swap but havent made much progress yet. My main reason for the swap is to have a taller set of gears to work with. 3 speed dont give ya much options.

The main problem with a swap like the NP435 is that the shifter will come through the floor under the dash. The Jeep V8 transmissions have a long adapter that moves the shifter location back. The stalk can be bent so you can reach it.

Not much difference between the NP435 and the Jeep T-18 ... if you can find a donor, take all the pieces you need from it.

Yes, and from what I understand, you about have to convert to hydroboost to get the slave cylinder to clear the brake booster...

This is the #1 reason I have swayed away from the swap...it would just be another needed mod...and added $$$...

??? The AX 15 has the slave either internally (bad idea) or externally on the bell housing. How would that interfere with brakes?

I never seen or heard of this ????

It uses a Hydro clutch so you would have to convert you master to have one also and find a brake peddle Assembly

I completed the swap last summer. Swapped out the 727 for a T18. I spent the time to find the correct donor parts and can say for a fact it is a very easy swap if you go with and gather the Jeep parts. My truck is an 1983.

I my case I wanted all the stock parts for the conversion which for me included finding a manual tilt steering column, pedal assembly, linkage, and of course a t18 with stock adapter, bell housing, linkage, etc. Found it all on craigslist over a few month period.

One detail item to remember - you need to bypass the neutral saftey switch - easy to do, but very frustrating if you forget to!!

I rebuilt the T18 and the NP208 prior to the swap - very stright forward & all works quite well -I love the granny 1st on the trails.

I beleive you will have to manage adapters for the NP435 which may make the swap a greater challenge from a cost standpoint and perhaps a linkage standpoint.

This is from Kris, who put an AX-15 in his wagoneer:

"Fab'd a spacer to move the vac booster off the firewall to fit the clutch master. Vanco made and installed a longer rod in the booster. Hydroboost solves this issue, but I needed to stay vacuum."

I'm guessing it the new clutch assembly/hydraulic setup doesn't clear the stock brake booster.

Heres a pic of mine. If I remember correctly, the spacer I made was 2.375". It is used in addition to the factory aluminum mount.

The master is from a '92 yj.
