Anyone have information on where to find a brownie box or some other multi-speed gear box? Looking to put one on my 76 F250 4x4 390 4spd manual.


Thank you

 

Probably either CL or junkyard searching....

 

that is gunna be a hella setup.
I hope you gotta loooong wheelbase B/C that brownis(a divorce setup) is gunna add length to your powretrain.
You would only be able to use 4x4 with the brownie in direct.
I know a guy who put in a plain ol' 3 speed Saginaw behind his primary tranny.
It gave him two underdrive gears and direct.
He put in the tallest rear end ratio he could find and it worked out great
fully loaded he used 1st in the Saginaw
around town 2nd and out on the freeway he used 3rd which equaled direct.
As for me...
I just drive slower
I got my gears setup for 65mph and installed a cheap universal cruise control.

 

Be easier to adapt a nv5600 six speed and transfer?

a 4 speed tranny & twin stick NP205 & brownie would make an impressive forest of shifters sticking through the floor
'prolly be tricky to set it up so none of the shifters hit each other
your tranny hump would look like swiss cheese

 

Hi,

I recently installed a Ranger Torque Splitter on my 70 Highboy. It goes in-between your bellhousing and transmission. You have to move the 4-speed back 7 1/2 inches and only have to shorten one drive shaft. The intermidiate drive shaft (7 1/2inchs). The Ranger is a 2 speed unit,.... direct 1:1 and 27% overdrive.

The Ranger can be used in all gears, .... 4x2 or 4x4, High or Low range.

Just some more food for thought.

 

If someone was to figure out how to mount the Brownie between the main box and t-case it could be used for all the time. The problem is that the Brownie is about the same length as the intermediate shaft, requiring all three boxes to be coupled directly somehow. My buddy has a couple of them sitting around which has allowed me to play with the idea but apparently I'm not smart enough to figure it out.

 

The ranger torque splitter seems to be a good option. Advance Adapters also makes an adapter to bolt an NV4500 to your stock bell housing. Both require shortening of the center drive line only.

 

I bookmarked this place a while back. They seem to keep a few Spicer 3 speeds in stock. Not sure how 'up' you are on these, but Spicer bought Brown-Lipe in later years and produced the boxes under their brand.

Here's the Ranger overdrive unit.

Possibly a bad link. All I get is "runtime error."

 

You're not missing much. All it does is take me to LKQ's search page.

See if this one will work for you. This is the page that link took me to.
