Manual transmission when shifting engine revs for awhile before it shifts into gear

SOURCE: 2002 Ford F150 5.4L hard shifting

Have you ever changed the transmission fluid flush and replaced the transmission filter?

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.

Clutch may be smooth but this is a sign of the clutch needing replaced. Some of these models have a linkage adjustment under the hood. Others are hydrallic and need fluid. Look under the hood where the steering is and see which you have and address accordingly. Good luck. Check on costs of clutch replacement.

SOURCE: we put another transmission in a 95 windstar and

The gear is a bad one too. go for a new transmission please.

SOURCE: E40d trans will not shift into 3rd or 4th gear, only rev. 1+2

check or replace your thottle position sensor tps that trans needs to know where the throttle is to shift if it is bad it will do as you say wont shift to third
another telltale is it will act like it goes into lockup when shifting into reverse and stall the engine
