I have a newbie question for you guys. The pumpkin of my truck seems to be stuck in low gear. It has been like this since I bought it. The truck is a '46 Chevy 2-ton but the differential says GMC. I do not see any provisions for a vacuum line or a manual shifter to hook up to it. There is the proper shifter in the cab for the tranny and one for the 2-speed which does not control the transfer case. Please see the photos in my signature and tell me what the heck is going on.
Thanks everyone!
Sincerely,
j

The shifter arm is sticking up on the top left side of the diff., it has a 90 degree bend in it, the strap is attached to where either the vacuum or manual shifter would attach. You could attach a manual shift rod, or find a vacuum shift unit and all the control stuff, hope that helps | | | | | Joined: Jan 2008 Posts: 165 Wrench Fetcher | | Wrench Fetcher Joined: Jan 2008 Posts: 165 | The two speed lever is held into low with a bracket that bolts onto the front of the rear end, you'll need to get the correct linkage and lever for this set up as it is a lever shift 2 speed. | | | | | Joined: Dec 2006 Posts: 720 'Bolter | | 'Bolter Joined: Dec 2006 Posts: 720 | Lookin at it, that looks like a Eaton 2-speed axle, at least it looks very similar to mine and the ones I have in my manual. Odds are the linkage broke and the owner at the time opted to leave it in low and remove the broken parts.
Might find a shift fork & an electric shift motor to bolt on there, or the vac-shifter and all the trimmings.
1956 GMC 370 dump " 'Tater "1970 VW Volksrod "the Black Bomber" 2007 Chevy Avalanche 2020 Jeep Cherokee Trailhawk, 2005 Harley Davidson FLHTCUI I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion! :P

It wouldn't have had the GMC axle in it originally. | | | | | Joined: Jun 2007 Posts: 12 New Guy | | New Guy Joined: Jun 2007 Posts: 12 | Thank you guys so much for the help!!!
I think that i will try to see if I can just put it in high and modify the strap to keep it there until I can get all of the parts I need. I do not plan to haul any really heavy loads in the near future anyway.
I sure hope it goes into high gear!
Thanks again, guys.
