The Stovebolt Site Forums The Parking Lot Big Bolts 2 ton shift stick slop

Hi got a 2 ton 4 speed that has a huge amount of stick slop was hoping to find an exploded diagram here to figure out what the problem is the trans shifts ok but I have to be very carful of were the stick is thanks for any and all help.

pvcphil, A year may help someone determine what transmission you have. I have a 46 2-ton and has a lot of movement in the shifter. Certainly not like a modern anything, so what you feel may be normal....

Welcome to the Stovebolt. Lots of great folks and information on here.

Randy is right.
The old trucks have a lot of stick slop.
My 46 one owner 2-ton with about 50,000 miles is loose as a goose, as is with a few other ones I have driven.

BTW, welcome to the group and start asking questions.
It takes about 4 or 5 posts, and you can do PM's.

Sorry about the year it's a 1946. I'm 66 so these are what I cut my teeth on back on the farm. Let me try again on explaining the slop. Say your in 4th gear the stick should stay straight in line but mine I can move why'll in gear in a U shape same in 2d and 3rd not so much in 1st ore reverse. The H pattern is actually pretty tight but with all the swing in it I miss the slot.
thanks again.

Sounds like the shift forks inside the tranny are worn out.
That happens when the driver rests his hand on the stick while driving.
I found out the hard way, years ago on a Jeep.
First, drain the tranny into a clean container, like the wife's mixing bowl and check for brass. (could lead to divorce though).
Pop the tranny top and inspect the forks and anything else you can see with a good flashlight.
Run a retractable magnet up the drain and down thru the removed top to see what metal shavings may be in there.
That will give you an idea about the condition of the tranny.
Then post what you find.

I'm not sure how many similarities you'd have with the SM465, but I got rid of a lot of shifter slop with these steps:

Also, the finger coming out of the snout in his picture had a couple o-rings on its shaft, and it was roll-pinned inside the snout. I guess the o-rings were supposed to cushion it while providing a snug fit, but they were shot.

After looking at the link pvfjr sent I got brave and pulled the stick out. Well the slots that the roll pins ride in are totally shot looks like I got some welding to do and some filling to do. I'll try and take some pic's as I go along and post them that might help someone down the line. thanks again.

I was going to suggest checking that. I ran into that on my '67 GMC pickup when I got it. My brother who is a welder filled in those slots. Made all the difference in the world.

I'm glad you narrowed down the issue. So is the stick assembly otherwise solid? No cracks or worn out o-rings?

well got it all welded up worked out fairly good. Still need to replace the roll pin's. As to the O rings if there were any there they are long gone not sure if the older non cyncro trans had them? The picture idea didn't work out I just plane forgot once I started work on the shifter. So for now it works and shifts like a 20 year old truck instead of a 70 year old one. Thanks again I'll post again maybe with pic's when everything is done.

I fixed my old 4 slider in a similar way. I ground out the slots on the shifter stick ball until they matched the width of some (I think) M4 hex head high tensile screws. I drilled out where the roll pins went and put the hex head screws in, heads inside and nuts outside. I think, as I recall, I threaded the roll pin holes to take the M4 screws also. This repair worked really well.

I had the excat same problem on my 46' GMC 1.5 ton. I replaced one shifter fulcrum pin (Ebay) and just rotated the other. Then added weld material to the slot in the shifter. It helped but only marginally. I found a new used transmission at a swap meet as my lower countershaft bearings were making noise. The truck shifts far better and without all the grinding in between shifts. My old shifter went up the ash tray handle and beyond and the new used one stays about 2"-3" away. What I learned these transmissions actually worked very smooth and tight when new. I had assumed they were were built sloppy.mjl
