    From what I understand from the history of the GMC M135 / M211 after WWII the Military was looking for a replacement for the GMC CCKW. But the Military awarded the contract to the REO company for their M34 truck.

    https://en.wikipedia.org/wiki/M35_2%...on_cargo_truck

    This upset GMC as they felt like they were certain to get the continuation of the Military contacts due to the success of the CCKW. So GM took it upon them selves to build the GM M135 / M211 factory and truck production.

    I am sure there was a lot of politics involved around it but the Military allowed the usage of the M135 / M211 as Experimental vehicles while they were being approved. Hence the 'X'.

    Then Korea and the Cold War happened and the increased need for trucks. The M34 became the M35 which then grew into the M35A1, M35A2 and M35A3. And at the same time the Military approved the use of the M211 removing the 'X'.

    A few more pics for everyone for our "starting point", she will be painted the darker Forest Green color with Army markings, and also a cargo cover when completed.

    Is Eastern Surplus doing your transmission overhaul? If not, could you find out who is doing it and and an estimate on getting one done?

    I would be interested in knowing where to have it done and what the cost would be. I have not been able to find anyone that works on these transmissions still.

    So far Eastern Surplus has gotten mine to shift "OK" so I may not need a full rebuild (just a good "tune up"), but they said the shop they use for transmission rebuilds would do the Hydromatic if needed. If you call them ask for Doug as he is the project manager for my XM211. Additionally, I spoke to the following companies just a few weeks ago during my research of these vehicles knowing the transmission was the weak link with little support these days. Hope this helps. If I do have Eastern Surplus do a full rebuild I will let you know the cost, I expect between $3000-$4000.

    Transmissions by Gene (www.restorationhydramatics.com) - I spoke to Gene, he has done them for people with M24 Chaffee tanks as they basically used the same transmission(?), price for a complete rebuild is $3985.00 + shipping to & from.

    FATSCO (www.fatsco.net) - they have 3 types of Hydramatic rebuild kits available and one for the gear reduction unit under "Hydramatic - Military Truck", I spoke to Junior at x105, the only missing part is the Extension Housing Gasket so save the old one to use as a pattern to make a new one from gasket material.

    What was your transmission doing before they got it to shift "ok"?

    Holy smokes, that seems pretty spendy $3985! Don;t really have anything to compare to other than a local rebuilder I have used for a bunch of trannys told me to budget $2000-2500 if I need to have one done. This rebuilder I know is pretty much awesome.

    Fastco seemed like they really knew what they were doing. Can't remember who I spoke to, but he had torn them down personally. he didn't have the reduction unit gasket and I think a few other parts in the reduction unit when I called(cuase nothing else but this series of truck used it as I understand-dont know about tanks), but maybe the fellow you spoke to knew more where stuff was stashed. I would love to tear one down to see. I've rebuilt a few autos myself(Ford FMX's, C6+turbo hydramatic 350+400). These would be much older, but would love to get the shot at one. I wouldn't be crazy about having to pay for it though(although the cost of it really isn't bad for the master kit). I'm gonna picking up a 211 this next week. Knowing my luck, I've now condemned it to having a bad tranny....

    Welcome aboard Forrest. Where did you happen to find this truck? It looks to be surprisingly like one that I had a lead on recently. Nice clean 52. I didn't have money to get it though. Timing is close enough that I believe this is the same truck.

    With regard to my transmission, unless you let the truck idle for 15-20 minutes to warm everything up it would slip a lot, and a pickup truck had to be used to get it up on the flatbed due to the steepness of the ramps as it was slipping badly.

    I saw this XM211 advertised on armyjeeps.net about 6 weeks ago, it had been a Florida truck its whole life, thus the very clean body, and mileage was 24,000 with mostly all original items.
