TRTXL 1070B 12 Speed

[Brandt]

Selling this trans. It has issues!  Check this post to see if you want to tackle the issue.  Otherwise it ran fine until I goofed it up. It has 239K miles on it. It is complete minus the stick (but I have the shifter knob/switches).  I have no idea on the value - throw me an offer.   It is located in Powell, WY and I can ship from Billings, MT 59101.

heck of a tranny!!!  jojo

Would be cool to put in my B model.  The old 237 would never hurt it.  But distance and cost to "fix" would likely make it a moot point.

I'd love to learn how to tear into one.

I will be driving from Cody WY to the Ozarks in Dec. Possible delivery along my route.

My brother may be traveling from Cody to Baltimore in Oct. He might also fly, so this isn't 100%.

does it have the 11 bolt SAE bolt pattern that an Eaton would have? I know the t-2000 series of transmission's do but I don't know about the TR series. 

[Brandt]

I count 12 bolts in a circular pattern.

Is this worth $500???????

[Joey Mack]

I would buy it in a heart beat at $500.00...  but I am In N.C.   Theres a rebuilder in Michigan that fixes them, but I can not remember their name.... maybe they would buy it..  IMO, that is one of the BEST Mack tranny's..  please dont scrap it..  sit on it til you find a good dollar for it..  it is a classic REAL tranny... jojo

[Brandt]

I found a rebuilder in FL but nothing in MI.  If you come up with a name or number - let me know.

I'll trade for a good rifle or handgun!

[Joey Mack]

Buddy If we were closer...   I would let you pick from a few Rifles..  Dammit!!!! 

[Brandt]

Do you run up toward Philly anytime??

[Joey Mack]

No sir..   No more trucking for me..  I bet there are a bunch of guys in P.A. that would buy it.....  jojo

[Brandt]

Finding them is the problem

I'm not really up on my Mack 12 speed knowledge. I know there were several versions of this transmission produced. What exactly is a TRTXL 1070B? How does it differ from T-1070, T-1070B, TRTXL-107, or TRTXL-1070? I know what they are but just not the differences in each model. I drove an Eaton Super 10 for a while and understand them to be the same principle except for a deep reduction for gears 1 & 2. I might be interested in this transmission to have on hand for a future project.

[Brandt]

I can't compare it to the other ones you listed, as this is the only Mack trans I have experience with.

You are correct in that it shifts like a Super10, with an additional 2 deep reduction gears. It also has 6 reverse gears and a Neutral position on the shifter(that is what got me in trouble with it). I haven't pulled the dash air switch (for the deep reduction) yet, but it goes with it.  It is a .73 or .78 OD and runs out at about 70mph with 4.42 gears and 11R22.5s

 

Text first as I don't answer calls that I don't recognize (or leave a message and I'll call back).   303 two04 three 28two

I called and spoke to the local Mack dealer. As expected, they are clueless unless it was made after Volvo.  Try posting in the Transmission section, I'm sure somebody here can tell you the difference.

I still have this and don't want to scrap it out just yet.  I get it that transportation is the issue. If interested, let me know, sometimes a transportation issue will present a solution.

[Brandt]
