My IH 706 is mostly a chore/pto tractor so I have not been pressed to fix this issue. But, would like to get it working as it should again. While running an auger in the fall of 2017 I noticed the red light was glowing on the dash. Knowing the light monitored the MCV and engine oil pressure I affirmed that it was an MCV problem by trying the steering and brakes. Sure enough, no steering or brakes. I just thought it had lost its prime. I did over fill the transmission case, blew air into the transmission case and changed the filters. That did not fix the issue, but driving it around slowly it finally took and worked fine. Well, it lost it's prime again on the auger that fall and I could not get it to work again. I just figured a weak MCV pump. So, I put a new Hy Capacity MCV pump in it. Also put new springs into the MCV valve body. Now I have great power steering and brakes, but no TA in direct drive (TA forward). Also when you are on the road it will coast down hill (TA not holding it back). So, new MCV pump and reworked MCV = always working good steering and brakes, but non functioning TA. I thought the TA was working just fine before I had it on the auger that fall. In fact I pulled the auger five miles to that farm with the tractor. I honestly can't remember if I was in direct with the TA. How could the TA go from being good to failing without really doing any work? Anyway now it doesn't work. Did I screw up something when I went through the MCV assembly??? I pulled all of the valves and put new springs on them. I believe the red light comes on when the TA is pushed forward and is off when the TA is pulled back. I hate to split the tractor and put a TA in it if that really isn't the problem. Should I pull the MCV valve body off and check it over again or is the TA toast? Help!!!!!
