Basically I always want to make my truck something different than anyone else has. That pretty much sums it up. like a member posted earlier in the thread "Think outside the box" its fun to figure out what makes things tick and change it lol.

 

I think that it would be a cool project but why do some people need twins and massive amount of non towable horsepower? They do it because they want to I guess, personally I would just like to keep the thing reliable. If I had a 4 door 4x4 dually sitting on 19.5, with a new 8.3 and a jake brake, air ride, then a brownie box I would put in. Keep this thread alive it is interesting.

 

Yes, it can be managed on a standard-length truck.

You will need to either divorce-mount the 205, with the auxilliary in front of it, or leave the 205 as-is and mount the auxilliary behind; no big problem, so long as you remember that the auxilliary must remain in "DIRECT" whenever the 205 is in gear.

I don't have a definite weight figure, but my 4-speed auxilliary seems to be about twice the weight of the Getrag.

I will try to remember to get an overall length measurement.




I may be weird, but I never even notice I am shifting as I gain/lose speed; it is just as automatic as working the throttle and steering.

I am always driving some kind of truck or another, bull-wagons, dump-trucks, milk-trucks, flat-bed gate-trucks (I do live within ten miles of the "gate capitol of the world").

One big thing I do notice, when I get out of a big truck after a long trip, is that I nearly push my clutch-pedal through the floor-board, it works so easy, compared to the big trucks; and, the lack of feather-touch air-brakes becomes apparent real quick.

 

Here is a picture of a 3-speed in a Ford :

And, we ain't the only ones with similar ideas; here is some good reading :

Enjoy.

 

That would be great if you could find out the total length just to get a rough estimate. I am still grasping this but can you still drive with the normal 5sp with a brownie attached? The last link does not work because I do not belong to that forum.

Bearkiller Thanks for the info

 

Yes, you can shift the Getrag same as always; the advantage is you can do so in however many ranges the auxilliary has.


Or, you can split-shift.


Or, you can shift the Getrag from 1-to-5 with the auxilliary in DIRECT, then shift the auxilliary into it's over-drive and idle along at 70-MPH.



It is common coffee-shop gossip that multi-poled trucks require one to hang their arm through the steering-wheel, while shifting two (or three) poles at once; most of the people that make this claim never drove anything bigger than a Datsun.


I have driven many multi-poled big trucks and have yet to have occassion to move more than one pole at a time.


I am not saying that it isn't possible to do the arm through the wheel thing, just that it is not necessary.

 

but it does look cool on youtube, with a mack 5+4

 

Man, these old brownie boxes are hard to find. I am gonna keep looking though, i think it would be cool and i would like to have a extra low reverse so backing up to a trailer is not such a fast paced experience. And being able to have more choices in your final drive ratio would be nice in alot of situations. With my truck being a 2wd, it should't be too hard to get a brownie hooked up. I wish my grandpa was still alive, i'll bet he could have me one with a few phone calls. He knew every junkman and stuff like that for i don't know how many miles!

I have been have a hard time as well. I'm sure that we are not the only ones looking for one either.

 

Those that want reliability and durability in an auxilliary unit are hoarding them.

They are bigger, stouter, and better than anything the aftermarket has offered.

 

Learned to drive truck on an old '73 GMC 9500 with a 6-71 Detroit and a 5 and 4 that was not fully progressive. In that case, with the 5 or 6 speed trannies used in the Dodge, you would really end up using only two of the available "splits" on the Brownie. This would probably be the 1:1 ratio and the overdrive hole. If I remember right the overdrive was only about 12% so in some shifts, like between 3rd and 4th gear on the Getrag 6 speed, you wouldn't be able to use the overdrive as it wouldn't really be a whole lot different than going straight from 3rd to 4th. Check out each gear ratio very carefully in the tranny you plan on putting the brownie behind before making the assumption that you will be able to have useful splits for each gear.
