Hard to get manual trans into gear, warm weather

[Dugan]

02 ranger 4.0 5 speed 4x4

It was acting up last year, on hotter days it would act like there was an air bubble in the hydro line. I flushed out all the fluid and got the air out of it.

Worked fine up till today when its been less than 30 out and today its 60.

Wont shift into gear while running but will turned off.

Sounds like air somehow got back into the system..


Bad slave?

Master and slave likely need to be replaced. Put it in first gear engine off, push clutch to floor and start. If the truck wants to jump forward or tries to move the clutch is not releasing. If it doesn't creep the pilot bearing might be dry and dragging. Either way the transmission has to come put

yep what I thought haha, damn these internal slaves.

Seeing that it did this before and I was able to fix it for about a year I think there might be somehow an air bubble trapped in the system.

Im going to be making a setup to force bleed in reverse through the whole setup

This way I will see if air gets passed through, also will clean out the fluid if its contaminated.

10-20psi should be a fine pressure.

There is a known successful method of bleeding these systems. Look it up.

You have to remove the master cylinder and line and bleed them together.

Yep did it, and have done on many a ranger, worked for a year. Now its back to the same issues.

Im gonna try to push the bubble out, if not i got a prefilled system on order for 113$ comes with everything. Commerical accounts are a wonderful thing
