Tractor is a Farmall 706. This problem started last fall when the tractor was on a grain auger. Got up on the tractor to start it to auger some grain and noticed the red dash light was on. Engine sounded fine with no knocks, oil level was good. Believed right away the light was coming from low pressure at the multi control valve. Tractor had no power steering and no brakes. Did over fill transmission. Did change the hydraulic oil filter. Did get the pump to prime once and everything worked fine. Eventually lost steering and brakes again running the auger. Decided it was the MCV valve pump. Pulled the pump and installed a new pump. Put all new gaskets in the MCV and all new springs. Think I got the springs all back in correctly. Anyway when I got everything back together this is what happens. In the low side of the TA the dash light is off. When you shift to the direct or high side the dash light comes on. Also drove the tractor between farms yesterday and the tractor coasts or free wheels down hill in the low side. Have not ran the tractor in direct due to loss of lubrication to the rear end. So, now several people are thinking I really didn't have a MCV pump problem, but actually a TA problem. Prior to putting the tractor on the auger last fall it didn't show any of these problems. I am just trying to make sure I don't replace the TA when that isn't really the problem. Prior to replacing the pump I think the light was on whether the TA was in high or low. Now the light is just on in high. Like I said I did rebuild the MCV - could I have screwed up something there? I must say with the new pump it always has steering and brakes whether in high or low on the TA. Just found out about the free wheeling downhill yesterday. Thanks.
