D-180 won't go in reverse

[Tractorstien 1]

My 74 d-180 automatic works fine except for reverse. When put in reverse I have to throttle all the way up and then it backs up as slow as a snail. What do i need to do to fix this? Please help.

Probably needs adjustment

Well adjusted the linkages, didn't help. Then I undid the linkages and pushed the transmission lever all the way back, still goes slowly. Any other suggestions?

Sounds like you're gonna have to start checking valves and springs. See the trouble shooting guide posted above.

Changed filter and it is working better, so now I will change the oil and filter again after a few hours of running it. It did sit outside for 6 years and didnt have the filter and oil changed in 9 years or more.

Did you put in new O rings and backer rings between the manifold and the motor? did they seat correctly??

 

Does the midmount lift work??
