transmission top cover

[kosovoruss]

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.

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!

[kosovoruss]

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?
