I found a 1970 C70 that was in a fire tires didnt burn but i just want it for parts mainly the brownie. I want it for my C70 the owner said he couldnt down shift it but just why i couldnt get out of him. How are they to shift ? The truck is priced write if you need alot of parts but not if the part i want isnt any good.

I'll bet he didn't know how to RPM match- - - -most Brownies ARE NOT synchronized- - - -gotta shift them like a crash box! Slip the box out of gear without disengaging the clutch, rev the engine up until you can slip it into the lower gear, and drive on. The Mack Tri-Plex I learned to drive big rigs on had a 5 X 3 setup, and I could go up and down all 15 gears without using the clutch. There's no need to double clutch unless you just enjoy exercising your left leg.

Make sure to get the remote shifter, linkage is easily made from EMT tubing. Find out the model number, too.

It's fairly simple to make a Brownie shifter from the top cover of a trashed-out SM-420 4 speed transmission.

FWIW Ya gotta use the clutch on the road test for your CDL. When I upgraded from a chauffer's license to a CDL I didn't bother with the clutch and the examiner marked me off one point for each shift. I had to come back the next day and take the test again and pay the $75 again.

I'd love to see that examiner drive a 4 X 4 transmission setup with an air-shifted Brownie a few miles and try to do it using the clutch for every shift! I doubt if the transmissions would survive!

A teacher, but always an apprentice.
So I’m kind of highjacking this as my sm420 acts up like this. I can’t shift OUT of 3rd most of the time with the clutch. I have to have my revs just right, pull it out of gear with no clutch, downshift and carry on. It goes into 3rd beautifully, always. I’m guessing now I have a bad synchronizer? I thought it wouldn’t affect shifting out of a gear, just into a gear. I want to make it easier for others to enjoy the truck.

Help?
