Allison TX 200-6 Question - Steel Soldiers::Military Vehicles Supersite

ALFA2 · 10-22-2009, 22:56

I just had a question, if anyone knows what is the overall length of an Allison TX 200-6 ( from front edge of the bellhousing/TQ housing to rear edge of the output flange) ?

This transmission was used behind LDS 465-2 approximately 1969 +-
Also, if anyone has one, or knows where a used one, or rebuildable one can be found, any help is greatly appreciated.

Thanks,

Ah yes, the ones used in the M656,757 and 791 vehicles.

Thanks for responding Stalwart, do you have OAL measurements of this transmission, or any other information about this transmission that may be helpful?

Thanks Again.

About 30 inches long.
This was exclusively used on the 8x8 trucks listed by Stuart above and would be hard to find. The injection pump governor also had a cam to keep engine from overrevving during the shifting. The -2 engine and the -6 transmission work well together.
How do you intend to use it?

Thanks for your help cranetruck, I am interested in this transmission, to see if it will work in a M36a2, with an LDS 465. Also it is interesting to find out why they only used it for so few years, just too expensive, or did it have some unusual problems, that could not be fixed?

Please let me know.

Thanks again.

this would be a really bad choice for any deuce as it is not overdrive and only uses the top 4 speeds for on road use. very old, no parts available, etc. used in a lot of civilian trucks early 60's. a 3060 would be much better. (without the P it is not so long)

Thanks for your info tom, I am not very familiar with the 3060, what trucks did it comer in, and is it an electronic control or a hydrolic transmission?

Also, does it have overdrive?

Thanks in advance for any help.

According to the information I have, the civilian TX200 transmissions were adapted for the military and used in vehicles like the M113, however the -6 variant was designed for the M656/xm757/xm791 trucks alone, with whatever the modifications may have been.
These vehicles were not designed for the highway, so overdrive wasn't important. Max speed for these amphibious trucks is 50 mph (Tom is always looking for more top speed.

).

Thanks cranetruck, I looked at the specs of the 3060 Allison, and it is an electronically controlled trans, which I am trying to avoid, also it seems pretty expensive, as such things go, so unless I find something great, I am going to keep looking in the older hydraulic type automatics, as top speed is not primary here. May be with tire size it may go to 55-60, but load capacity and offroadability is more important here.

Thanks again.

try driving it around in 4th for a while to get an idea of speed. you will not find an automatic with o/d without going to the electronic allisons.
