warn over drive?

I just got my new 71 cj5 home.... it has a 225 ci engine and 3 levers inside the cab on the floor.... stick and then 2 to the right of the tranny..... there is one that is longer and then the one closer to the front of the jeep is shorter.... what are these other two? which is which? how do u use the over drive?

Thanks in advance

 

the reason i put warn over drive on the title is i climbed under hte jeep and the data plate said warn over drive... thanks

 

The overdrive is just that - an overdrive. It's a planetary transmission that has a 1:1 ratio (ie straight through) or a 0.75:1 overdrive ratio. You can split the gears with it, leave it in overdrive all the time, shift into overdrive on the highway, or any other combination of transmission gear and overdrive in or out. It even gives you two reverse gear ratios!

The 3rd lever is the 4WD control: 2H-4H-N-4L front to back. And yes, the overdrive will split the 4L gears too. You have 12 ratios forward and 4 ratios in reverse - 3 forward gears * high or low range * overdrive in or out.

 

I'm sure it has been covered if you search a little but:
the short lever is the Xfer case, 4h,2h,N,4l
The long lever is the overdrive (actually more of a gear splitter). The OD can be used in any gear for a 25%OD (IIRC OD is the lever forward, could be wrong and sure I'll get corrected if so). Use the OD as any other gear.

Edit: And all the above post were added while typing, and answer the question.

 

That's not right. The single-stick Dana 18 is 2H-4H-N-4L.

(The Dana 20 is 4H-2H-N-4L, starting in 1972).

So, You manage to score a 71 with the coveted flanged 44 in the rear, :v6: and an overdrive you didn't even know it had. Nice score! Some guys get all the luck! Welcome aboard!

 

i did not know about all that but thanks... i am even more excited now!!!!

 

congrats but does it have a build date sticker on the dash?

 

i dont know i will try to look tomorrow..... what exactly am i looking for?

 

rectangular black and yellow sticker about 4 inches long under the headlight switch

 

nope no sticker there.... also where can i find the vin on this thing?

 

There should be a stamped metal plate riveted to the firewall, under the hood, on the driver's side.

The overdrive is a cool thing, but you probably got that...

We need pictures :v6: :AMC:

 

This thread is worthless without non text based descriptions of your new find.

 

yup...pics needed

 

:uwop:

:uwop:

 

no pics yet but here are the numbers on the fire wall....
8305037 366644

What does that tell me?

 

this one is pretty close.

 

That's your VIN. There's a thread with VIN information at the top of the forum.

I don't know these year's VIN numbers very well but the leading "83" means CJ-5, and the 366644 is the sequential serial number.
