I posted about 2 weeks ago about my TW35 slipping and found out the clutch was the cause. Now there is another problem. When the engine is idled down the hyd pressure light comes on and the dual power slips. I carried it back to the dealer and we went through the pressure checks as outlined in the manual. Here are the results: I have 2200# at the remotes. Next was the dual power test. We had 210# each time we tested. Dual power shift high to low, pto on off, differential lock, left brake, hold left brake push right brake. Next was the low pressure test. When we put the gauge on the lower line of the oil cooler, we had 0# at 1200 rpm. Manual says it maybe the relief/regulating valve or a blocked oil cooler. When I left, the mechanic was removing the valve. My question is, if this is not the cause, how do we check the piggy back pump on the back of the transmission? I am suspecting this because the tractor has to be split to replace it. Thanks, long post!
