New to the page. Not sure where to askthis question. MF 135 gas power. today stuck in gear. Played with it a little now I have 1st and reverse. shifter will not move sideways to engage 2nd or 3rd. have hear it could be shifter spring? Not sure. Is this something I can fix on my own or do I need to send it out for repair?
Thanks in advance
The following information should be helpful.
If straightline 2-3 shift is OK but straightline 1st-reverse is hard trouble is with detent plunger/spring assembly that is held down by steering box assembly. If detent plunger is rusty it will not slide up and down in trans rail bore as it should causing hard rail movement, not a common problem. Most have trouble when shifting too fast on 1st-2nd shift, lever goes to 2-3 rail but 1st-reverse overshoots neutral detent and goes into reverse, is corrected with HI-LO placed in start position to relieve driveline tension, then using a bar through trans oil fill to place1st-reverse back to neutral so crossover is restored. Sounds like you may need to remove steering box that holds down all 3 rail detents and springs to free up or replace 1st-reverse detent assy.
You may find the following images helpful while using the instructions provided above. They are from a Massey 135 tractor, but the transmission is nearly identical to your Massey 35 tractor.
