Case 1150 Dozer, I got slimed

We work outside on a Case 1150 bulldozer I&had on the back burner for way too long. We did have it running 3 years ago so now its overdue to get running again. I bought this machine with a blown up transmission. I then found a parts machine with a good transmission that we installed 3 years ago. In this video we move it up to the barn. We thought we had it fixed by adding more transmission oil but it seems to quit driving again. this time because of the torque converter. We think it might be the pressure relief or maybe the contaminated TCH fluid in the transmission. Connor finally gives me a turn at driving and a hose blows hydraulic oil all over me. Fun times.
