Hi, Working on my Early Lot 5 Scout Car that will only shift into Reverse. I removed the Shifter Tower to see if Rails are stuck and everything under there looks pretty clean. I soaked the rails with WD-40 and tapped lightly with a small brass hammer to no avail. I removed the Tower again and unbolted the 6 bolts holding the top cover (making sure the Transfer case and transmission were both in neutral before I started. I can move the cover side to side a little over an inch and when it is in the center (bolt holes lined up) I can lift it front and back a little over 1/2 inch. I have NOT tapped or pried cover for fear of damaging forks or parts. What am I doing wrong? When I did my Ford GTB the cover lifted right off straight up. Thanks.

Try moving the lever around as you lift the cover, or try it in different gears as something is holding it in place.
-
It Won't go into any other gear but Neutral or Reverse! I am going to jump into it again later in the week! Thanks!

I finally drained the Transmission yesterday with half of the Oil going in the driveway when the Filler plug fell into the Funnel, plugging it. On a Positive note, The Oil looked clean with no signs of water and not a speck of metal on the drain plug. I tested the Magnet and it was strong enough to pick up 3 grease fittings off the bench. I poured 1 qt. of Transmission through the Shift tower opening and will add more today once I find the capacity of the transmission! I can't find the capacities in all of those books I bought from Portrayal or the French manual I picked up last week. If I can top it off I can let it soak for a bit while I work on other parts of the truck. While I am here I have been Wire Brushing and Painting a bit at a time underneath and everything I encounter appears to be Matte Black and not O.D. like every other Military Vehicle I have owned. Early Lot 5. Any guesses? Thanks.

From the Operator's Manual, Section S-33AR, pg 3b:
7 1/2 quarts for transmissions w/out power takeoff, 9 quarts for transmissions with power takeoff for the winch.
You can also find this in TM9-710, pg 207, and TM9-710 TO 19-75A-77, pg 223.

Thanks!

I got 1st and 2nd free yesterday soaking it and "MASSAGING" it with a Big Rubber hammer! If I can get 3rd and 4th loose this week I will give it it's First Yard Drive in Many years! Clutching My Rosaries!

I finally got the Top cover off yesterday and it didn't take much if any effort to free up the 3-4 rail. I cleaned it up the best I could, Polished some rusty spots with Crocus cloth and tried to reinstall the cover to test! the 1-2 and the 3-4 appear to be lined up with their respective grooves, so far the Reverse fork won't seem to line up and now I can't get the cover off again! the transmission looks pretty clean inside and nothing looks out of place in my eyes. Am I missing any tricks considering this is the first transmission I have taken apart since High School Shop Class in 1973? When I get the cover off again I won't forget to take Pictures. Thanks.

Just a guess here, but maybe you have rust and or broken springs in the passages where the bearings are in the top cover. Thats the only thing i can think of that would cause you problems. Keep the updates coming and best of luck!
-
If all 3 forks slide back and forth will that indicate that the top cover is working OK? Again When I get cover off again I will take pictures! Thanks!
-
You are correct. If they are working with the cover off then ithere is no problem there. When you are trying to shift into gear, did you try spining the input shaft?
-
Draining the ATF TODAY! Going to try to get the top cover again and try it again! will take pictures this time!

Hello, after 4 weeks, The transmission is drained and Top Cover is off again. Transmission looks pretty clean and I don't see anything out of the ordinary. The Top Cover looks pretty good, Nothing broken or damaged. The 3-4 rail is stiff compared to the other 2 so I am soaking it with WD-40 and working it back and forth with a small Brass hammer and today I will remove the shifter and try to move the 3-4 Fork Back and Forth on the Rail. I worked at a Heavy Truck shop in the 90's and the owner is going to come over later in the week and look at it! While it has been soaking, I have been replacing from the Master Cylinder back with all new Steel lines and Rubber hoses. While there, I have been Power Wire brushing section at a time and painting it. It is an Early Lot 5 Truck and everything underneath and in the Deep cracks and crevices it appears to have left the factory painted Lusterless Black, Not OD like every other Military Vehicle I have owned! Any Thoughts? Thanks.

Hi, Spent all day yesterday cleaning, Oiling and Polishing with Crocus Cloth. The 3-4 Rail took a while but is much cleaner than when I started and the fork moves as it should. I am going to try and test fit it today and see what happens! besides lining the forks with the grooves are there any other tricks to installing the Top Cover? Thanks.
-
I spent 3-4 hours trying to get the top cover on, wiggling, Rocking, trying to line up forks, shining a super bright down in transmission tried it with shifter on, shifter off, Wiggling shifter with no luck. Will try again tomorrow. Any suggestions?
-
After 3-4 hours yesterday of trying to install top cover with no luck the Transmission that wouldn't shift into 3-4 looks like it is somehow stuck in 4th, The rear yoke will only turn when clutch is depressed. How do I unjam it when I pick it up again on Sunday? this is baffling the hell out of me!
-
Top Cover finally in place but I am back where I started from. It shifts into 1st, 2nd and Reverse but it wont go into 3-4. After 4 weeks of soaking in Mystery Oil I don't think anything can be seized. Shifter moves up a tiny bit towards 3rd but Nothing going back towards 4th! I am Major Frustrated, Going Back to the Books and will pick it up again come next week! Still open to suggestions, A Cigarette, A Blindfold, etc!
-
OK, I found a Collar/3-4 Idler that froze, Evidently the Mystery Oil didn't reach! I soaked with Penetrating Oil and "Massaged" it with my Small Brass hammer for a couple hours till it was nice and free and then tried it! All Gears are working now, Shifts smooth, And I added the first Gallon of gear Oil and will top off tomorrow! I made Top Cover and Shifter gaskets out of Silicone (Not my neatest work) but if it holds I will live with it! I will try to Yard Drive it towards the end of the week then move on to Windshields and Brakes! Thanks for all the Help and suggestions, This WAS an ordeal!

Wow, glad you got it going. Thanks for the details. It'll help some of the rest of us. Have fun now!
