Hi,it could be that your thrust bearing is whereing out,its the bearing that when you put your foot on the clutch pedle it connects with the presure plate that lets the clutch plate have movement to spin,like aney bearing can where out,unless clutch is ferly new you should replace the free parts,
clutch-plate
pressure-plate
thrust-bearing(release-bearing)
but of coures only if it gets worse
hope this was some help.

There might be some worn parts in the differential. If you have a limited slip differential the clutches will make that noise.

Ford ranger, getting harder to shift into gear


Suggest you check the fluid level of the transmission first. Remove the fill plug, and see if it is Below the proper level. Do Not fill at this time! There is a reason for this.

Then I would suggest draining the fluid. You are also looking for brass fragments in the fluid. Drain into a three quart metal, or plastic drain pan. (They are approximately 18 inches across, and 4 inches deep)

1.Manual transmissions use Synchronizer's made of a brass alloy. The synchronizers have tapered teeth, that the nose of the teeth can be worn down. Also a tapered surface on the synchronizer, that can be worn down. Brass fragments in the transmission fluid is a sign of this wear.

Some brass 'dust' will occur as normal wear. A large accumulation means you have problems. Transmission is hard to shift, is one of those symptoms due to this.

This link to an animated working of a five-speed manual transmission, may help to explain how the components interact with each other, and also help me to explain the Synchronizer/s.
(From Howstuffworks.com - Auto- Under the Hood - Transmissions and Drivetrain)

http://auto.howstuffworks.com/transmission3.htm

Looking at the animation, observe the 'gold' colored parts. In particular, observe the the pair of gold colored teeth at the rear. (The teeth are in a vertical row, going up and down)

Now also observe the blue colored teeth next to them, on either side. (On the spinning gears)
You are looking at a side view of the transmission, and also a side view of the Synchronizers.

The synchronizers are round just like the gears. They have a Female tapered surface where they meet the gear. The gear has a Male tapered surface on the outside of the gear, that matches.

When the female tapered surface of the synchronizer meets the male tapered surface of the gear, the friction contact makes the synchronizer start turning the same speed, as the gear.

Helps the gear being shifted into start turning also, and the - teeth of the synchronizer, - gear to be engaged, and - already turning components are synchronized to each other. They will be all turning the same speed, so shifting will be smooth.

This shows you Synchronizer rings for a 4-speed Muncie transmission,

http://cgi.ebay.com/ebaymotors/MUNCIE-4-SPEED-BRASS-SYNCHRONIZER-RINGS-1963-TO-1974_W0QQitemZ360137693405QQcmdZViewItem?rvr_id=&itemid=360137693405

Enlarge it for a better view.
See the teeth going around the synchronizer ring? Notice that they are pointed, or V shaped. When the nose, or tip of this V is worn down, a manual transmission is hard to shift.

Also observe the flat landing on top. (In this view it's on top) The flat landing has three rectangular cutouts in it. (There are used for Detents)

Come from that top landing, down the side to the teeth. This Side has a tapered surface. Tapered ever so slightly, that it is not readily visible in this photo.
When this tapered surface wears down, the transmission is hard to shift.

Summation?
1.Low fluid will cause hard shifting. It will also cause abnormally high wear of the synchronizer rings, (Synchronizer Rings are also referred to as 'Blocker Rings')

2.Worn Synchronizer Rings,
Broken or worn Detent 'buttons',
Broken Detent Springs,
and worn Synchronizer Hub's,
will cause hard shifting.

Should you not have an abnormal amount of brass shavings in your transmission fluid, and found the fluid to be low, you may want to just replace the fluid to the proper level, and see if this works first.

If so, I suggest contacting your Ford dealer, and see what the proper transmission fluid is for YOUR Ford Ranger. They will go by THE transmission is used in your truck, and will have any updates if better fluid has been developed since your truck was made.

I know dealers are expensive to buy from sometimes, but I implore you to use the transmission fluid they recommend.
It will have special additives.

Transmission makes a whine at speeds in excess of 20mph in all gears 1-5 and lower speeds 0-20 it clicks whether the clutch is in or not


I assume its a manual transmission, sounds like the gears are whineing, check the fluid level, most manual are splash lubricated so low oil means not lubrication, also could be syncronizers, bearings, worn gears, out put/ in put shaft

Transmission slipping when warm or hot?


Well it could be that the gear oil is low or the gearbox's gear teeth have worn out causing the gears to slip from their slot at higher speeds. Also check the clutch plates...............sodeep
