Spicer 6x4 transmission

I have never had the oppertunity to drive a twin stick mack transmission and I was wondering how they are setup. For example I have herd that the basic setup is a 5 or 6 speed main and a hi-lo-reverse secondary.

Is the hi-lo ment to split the gears? How does one shift progressivly through the gears?

I saw one mack on ebay that had a real weird shift pattern that loked like an incomplete H shift pattern like this :. If you are very heavy or in a hole and need to climb out you would put the aux or compound box into "low" and use the main in 1st. After the truck is out of the hole mud etc So basicly its like splitting 1st gear in half with the aux box. However the shift from "low" to "direct" has to be done carefully as if the truck is still climbing out of a hole you likely will miss shift as the slow road speed will fall very quick.

A B model with a 20 speed or 18 speed depending on what you want to call it "Quad box" shifts diffrently. I dont know why you cant use 5th in direct and low split but I heard the gears are spining to fast of the ratios are so close its useless to use those gears.

Hate to argue with someone that's put as many miles on a B as Trent,but the proper way to shift a 2 stick Mack trans,is like this. In lo-lo you can shift up thru each of the main gears,but unless in severe conditions,these aren't used much. Otherwise you shift it just like a Triplex,1st lo,direct,hi,2nd lo,direct,hi,etc. The 13 speed Triplex and 18 speed Quad were considered double over transmissions and in 4th hi,you could shift directly into 5th hi.

You may be trying to be a nice guy and not confuse Trent, but once you get the hang of it, both sticks can and have been in neutral when going from 4 low to 3 high, 3 low to 2 high, etc. Guess I should have added "till you figger out what you are doing",but I think in this case I was safe in leaving it off.

The gear you get when both sticks are in neutral Ha Ha. I think everyone has hit double nothin' a time or two.Filter 3. Industry Truck Parts. Category Transmissions.

I've had a Spicer C trans for awhile and I'm thinking of putting it behind my 12 speed in my RDsx. Does anybody know if this would be a good combination? I really only want it for a lower 1st gear but the OD will also be nice because the truck tops out right now around 60mph. It has some bearing issues I've also got to deal with before the install. Does anybody know if parts are readily available?

The trans is a air shift. The model tag doesn't have a P though.

Could be somebody swapped the top cover to air shift at one point. I've heard horror stories about parts for boxes like this. I don't know. My little box is working pretty well. The output is just starting to get damp after running it down the highway. I had one in my KW with a b behind a rto I put new bearings the box maybe four years ago. Don't remember where i got it but a kit was easy to find.

Well I need a mainshaft. Bearing went down where the main shaft and input shaft go together and it ate the bearing surface on the mainshaft. I took it apart Friday and noticed some marks on the gears but didn't think anything of it.

Talked to a guy yesterday and he said the gears have to be timed during assembly. He said he put one together one time without timing it and it roared like crazy, he ended up taking it to a trans shop to fix it. I'm back on this project after a long wait. I've just been too busy to fool with it and with winter coming on I have some time.

In my search for the correct yokes to match my driveline, I ended up calling TTC the people who are now building the Spicer trans. Talked to a guy that seemed very knowledgeable on auxiliary transmissions. Anybody with real world experience with a Spicer care to chime in? The issue I called him about is my current driveline has yokes and the biggest available for a is a Click to Post a New Message!
