Shortes auto between Ford Windsor and D300 or D20?

Ok, please humor me here.... just looking at options..



I love my manual transmissions. but.



Last time I was on some trails, I realized how much an auto would help. SO.... I am looking at ideas for a swap. Obviously it would have to be compatible with a Ford Windsor, and I want to keep the D300 or D20. I have both, so that leaves my options a little more open as to adaptability. I need the shortest, as the CJ5 with a T177/D300 leaves for about a 15" rear driveshaft.



Any ideas on my options?

HI, if your talking about going from brake to gas .. try a throttle cable to allow you to keep the rpms up while operating the clutch and brake to be able to hold the jeep while returning to the gas pedal.
good luck

I have the same engine you do and with my NV4500 and Dana 300 and Tera low gearset 4.56 gears and 33" tires it is almost unstoppable when the transfer case is in LO.

Idling along the engine will overpower the brakes. What gear ratio do you have? Maybe lower gears will help your problem.

Now on the street in 4 HI, I always start in second and I can kill the motor if I have the radio cranked up too loud and am not paying attention. I have considered using the A/C idle bump circuit which bumps the idle 200 RPM. The hand throttle is also a great idea.

I have 3.54 gears. I was just stopped on a couple hills, and it was kinda hairy trying to apply brake without rolling backwards when pushing the clutch pedal in to hit the brakes. The auto would give me a little more finesse.

Rick if you can find a C6 that came out of a 4x4 that might be made to work. I'm not sure about how long they are. Ford also used an FMX that was fairly sturdy. The Bronco used a C4 and with the right parts it can hold up to the rigors of being in a 4X4. Advance Adapters makes an adapter to mate the C4 to the 300 transfer case. https://www.advanceadapters.com/prod...1-adapter-kit/ cjponyparts.com sells C4 transmissions too. Here's another good source for Ford stuff https://shop.broncograveyard.com/Tra.../products/528/ I have spoken with them at times and they often have parts that are not listed on their website. Nice folks to deal with.

Put a lever type throttle on the shifter, works good if you only have the standard 2 hands.

One other thought I have had is putting in a line lock. When you are stopped, you could press a momentary switch on a button you could wire to the stick (they even have round shift knobs with buttons) and the brakes would remain locked. after you start slipping the clutch, you release the button and you will start moving. It is just an idea and much cheaper to try than trying to install a automatic transmission in a CJ5.

Rick we've all missed the boat on this issue. All you need to do is get a trunk monkey and have him jump out with blocks to put behind the tires. Many more things he'll take care of too!

Trunk Monkey - they have a fix for everything!!


I have the hand control, which is great for starting off, but when you are climbing that hill and cannot quite make it, you have to take your foot off the gas to hit the brake pedal and press the clutch in. ant I am fearful (in my inexperience) of hitting the brakes too hard and going over backwards.

I have found that the C4 is probably my best option. I have to do some measuring, but the Broncograveyard adapter on the C4 will let me run the D20 I have. Whether it is short enough, remains to be seen. I need to measure the T177 and Ford bellhouse lengths, do some addition and figuring, and see where I am at on things. This is one of those things like the flat fenders I am kicking around - Maybe, maybe not. I love the manual, love the idea of my T18 I have setting in the garage to put in, but that day on the trails had me thinking, especially how easy that Grand Cherokee made it around those tight turns we were on with his auto trans.



It seems there are 2 lengths, depending on pan fill or case fill. 1 3/8" difference in length if my math is correct.

That adapter is for an early Bronco D20. It is not the same in any way, shape or form as a Jeep D20 beyond both being called Dana 20s.

hello

i was bored today so i was doing a little research.
the c4 is the shorter of the two transmissions. the c4 bellhousing and transmission case is 17" before any tailhousing or adapter.

A/A shortest for a jeep transfercase is actually a jeep dana20 total length about 22 inches.

BUT it will be a manually shifted automatic. with that kit you have to run a manual valve body. there is no room for the governor in the tailhousing.

A/A second shortest if for a c4 to jeep dana300 which comes in about 23.3 inches
link: https://storage.googleapis.com/advan...f?1586212388=1

With that kit you will still be able to have a full automatic 3 speed.

Wow, thank you for catching that!

Thank you very much!



Now I have to sit down and decide what route I really want to take here.
