JD 755 crawler transmission problem

Post by 69Roadrunner » Tue Aug 11, 2020 6:01 pm

Hello everyone!
I’m new To this crawler form.
I am hoping someone On here can help me with my crawler problem. 3 weeks ago I busted the suction line on The left trans pump. I replaced all the lines on the pump with new ones and I also bought the JD Deere TM1137 manual so I could bleed the trans pumps and the control valve by the book. Well to make a long story short, the left track still does Not move. The trans pressure stays in the green for about 4 or 5 ft in either direction and then it just locks down.i have noticed on the left Trans pump the square manifold vaLve is cool while the right pump manifold valve gets good and warm . I’ve bled the control valves with a clear line into the reservoir while shifting forward and reverse like the manual said to do. It helped get a lot, but the left track still doesn’t move. If anyone on here can help me, I sure would appreciate it .
Thanks
