Manual trans stuck 3rd/4th gear - NP435 trans


Recommended Posts

My 86 f150 stalled out and now it seems the trans will only shift into 1st, 2nd, rev gear, unable to shift into 3rd, or 4th gear. From what I've read the 3rd/4th fork probably needs to be replaced. The question is, should I still be able to start the truck? Or do you think the clutch is burned out? I was able to roll the truck back 3ft to see if it could unstick itself, but all I accomplished was jamming it up against a snow bank. I can't work on it where it currently is, need to get it in the garage....

does it grind when attempting to use those gears?

I can't restart the truck to check. I can't get the shifter to engage 3rd or 4th. It's like it's jammed mid shift between 3rd and 4th, and I was only in 1st when it happened.

and you can't start it by holding in the clutch? that sounds like other issues

No, it won't start. Battery is charged and I can hear the starter engaging. Also , I can shift gears without pressing the clutch pedal...

it sounds like clutch failure to me. mechanical not burned.

and you can hear the starter engage? that would normally be a click with a humm if the engine/trans were stuck. no hmm might mean no load, as in you are hearing the solenoid only.
