I have heard all the for and against arguments and that will always be the case, the one thing that as a Cat fan is that we should be greatful Komatsu makes such a decent dozer because if they did not then the current Cats would not be as good as they are. Good old competition is a great thing and the benefits are for all.
That said it is hard to deny the facts and figures out there but when it comes to availability numbers you really need to back them up with the methodology behind how you come up with them.
Vote for D11R or a Komatsu 475
Your comment below made me think of an incedent at the Houston CONEXPO in 1980 or 81, can't remember the year for sure. Anyway, I was visiting with some pals over to the Cat exhibit and one said, "hey Joe, you want to see something really funny?" "Well sure," I replied. He said, "take a look at those guys by the D10, what do you think they are doing and where do you think they are from?"
So I wandered over closer to the nice new shiny D10, and there were about ten or more Japanese engineers from Komatsu all around, under, over, and in it. One would be taking measurements with a little ruler or tape measure, and another would be jotting down the dimensions and making notes in a little notepad. A third fella was taking pictures with a pretty sophisticated camera and his assistant was taking notes as well. They made no bother to hide their name tags, which identified them as all being from the Komatsu Factory in Japan, and sure didn't show any embarrassment at what they were up to.
I went back over to my pals and asked if they weren't just a little bit upset by what those fellas were doing. They said, "oh no, they weren't concerned." "The D10 in the show was an early prototype," one told me, "and would be changed in several ways before production." So I asked if they had gone over to the Komatsu exhibit and measured and took photos of all their equipment. You wouldn't believe the dumbstruck expressions the boys from Cat got on their faces. One finally said, "what for?"
Further discussion reveled that Cat figured Komatsu was 10-15 years behind them in technology at the time. The way they saw it, there was no use going over the Komatsu's in the show very closely. Oh, they had all been over there, but they hadn't seen anything that worried or amazed them, and were really amused and more than a little flattered by the Komatsu engineers flocking around the Cat equipment.
I've heard that Komatsu tried building a high sprocket tractor after that show and that after some testing and evaluating, decided against production as they did not see any great benefit to it. But this is just a footnote to the competition between the two, if you could call it that. It looked more like industrial espionage to me.

Basically the problem is the machine starts fine etc but has problems selecting gears, goes into reverse by itself etc.......
Temperature seems to be ok with the transmission....
The common thought at the moment is the computer might be cooked... The vehicle is only 2 or three months old.......
When the vehicle restarts the transmission resets itself and is ok for a very short time and then reverts back to selection wrong gears etc.
I know its not much to go on, just thought I would run it by you to see if you have herd of it before...
There is an error code 3 visible ....... I don't have access to what the error codes contain.
Thanks very much for your time, andy hints you could give me I will pass on directly.
A six-year-old thread springs back to life? Somebody needs to clean the tracks:
Impressive dozers to say the least. Here, back filling The Grand Canyon???
How is that elevated sprocket thing working out:
Brisbane is the capital city of Queensland, Australia. What are the Brisbane mines?. If the vehicle? (dozer?) is only 2 or 3 months old ,what happened with the warranty?
