Mystery Shifter in M38A1CDN2

I thought thats what would be there. And there is no way the army would put that on there. Maximum speed in those days for a SMP vehicle was 50, and the Willys could easily do 55 and even 60+ if the wind was going the right way.

Hi Mike

Around here the OD is what everybody wants for their Jeep little better road speed and a less frantic sounding engine.

But I have a second question, my `49 Lincoln has an overdrive and it needs both a mechanical engagement as well as an electrical one of the reasons is the car won't backup with the overdrive engaged (the electrical speed sensor and solenoid auto disengage the OD below 23 MPH) how does the Jeep OD work with only a mechanical engagement lever or does it have the speed sensors as well?

Cheers Phil

Speaking as a layman, I think a Warn OD just changes the gear ratios, so it can be used in any gear - even reverse. Is your Lincoln an early automatic? I think most automatics nowadays are like that too - OD only engages at highway speeds.

What I've read thus far on the Warn is that it is highly sought after by early CJ5 owners because it increases fuel efficiency, especially with mudder tires.

So the more I discover about my own truck, the more I am thinking that whomever bought it at auction in '87 started to convert it into a mud buggy but never finished. So while I would not have bought an OD to install myself (it isn't my daily driver), I will probably leave it on now that it's there. Few outside this forum would know that it isn't supposed to be there, anyway.

I just caught this thread and my M38 CDN had an original winch installed and the picture shows you where the shifter would have been as Rob Love pointed out ahead of the parking brake (on A1 models);

The same winch and shifter I believe applies to the M38A1 versions also.

Hi Mike

My 49 Lincoln has a 3 speed manual transmission with a plains rear end.
The over drive is of planetary gear design which because of its design means the car is free wheeling if you take your foot of the gas, engine comes to idle great for fuel economy but means your brakes better be good.

Your right about no one what the extra lever is for.
