I just put in allison transmission 6 speed. am wondering if the jd hygard is a good oil to put in there. I have it in there right now. when i fire up in the morning it shows no oil on dipstick. ill top it up, go work a bit and oil will start coming out of dipstick. rear tranny is same tranny but no issue. also when ill start digging,it will pull for a bit,then stop pulling. in allk gears i can get rpm to at least 1900 and tire will not spin. rear engine when i do the same thing,engine will labour but not front engine. Im wondering if wrong oil,oil possibly air locked, or faulty torque converter. thanks in advance for any tips
