Transmission shifting proublem M5R1 1997 FORD RANGER

Why does my m5r1 tranny not shift into 5th or reverse?

The clutch on that vehicle is draging : a very common problen on that vehicle : The Clutch master cylinder probly has some air traped in it causing insuficient travel in the slave and failing to completly release the clutch. Inside the box of a new clutch , there should be a 4 page tech buliten advising on three ways to bleed this clutch. I have the same problem on my son's 88.

You might have to try to adjust the freedom of clutch pedal,
The noise during shifting can be adressed to exessive wear clutch parts or again it might be a sign that indicates the not complete enabling the calutch
To find out what is causing the noise, set the parking brake, place the vehicle in neutral and start the engine.
If you hear growling or grinding noises when the clutch is engaged, the cause is the transmission input shaft bearing.
A squealing sound that occurs when the clutch pedal is depressed and held is usually caused by a bad pilot bearing or bushing.
A chirping noise that intensifies when the pedal is slowly depressed would indicate a bad release bearing.
If you hear chirping while idling in neutral and the noise goes away when the pedal is slowly depressed, the fork/pivot ball contact point is making the noise
Hope that helps.

Good Luck

Internal slave cylinders are known to leak , unfortunate it is behind clutch assembly , i would change both , clutch master and slave cylinder
