That sounds like a worn clutch.
This is a big job. You have to take out the transmission. If it is 4 wheel drive it is an even bigger job. The clutch is between the engine and transmission.
This just ensures that the fly wheel is perfectly even and to remove any warped spots . The clutch needs to be mated at even distance or the clutch will be prematurly burned out. Also if the flywheel is warped it can cause the clutch to slip as it is used.
Your clutch needs adjusted or replaced.
It is probably a shift solenoid is going bad and not letting it downshift correctly. This is a common problem on these vehicles. The shift solenoids are located in the transmission, you have to drop the pan to access them.
sounds like a fuel issue.
CLutch is buggered or might just be the clutch cable
will allow any air to escape and stiffen up the pedal.same
it all depends on the displacement of the engine. if it is a stock beetle, a 1600cc, you could probably expect between 25-30 or even 35 if you drive conservatively.
It all depends on your driving style and how often the clutch is used. If you do a lot of city driving, the clutch will last far fewer miles than if you drive hundreds of miles without stopping. If you "ride the clutch" when you drive, the clutch might not even make 20,000 miles.
If you are driving it correctly, not slipping the clutch or riding it, the clutch will last for 100,000 miles or more. Slipping means you are not allowing the clutch to fully engage smoothly. In other words revving the engine and trying to ease the clutch on. Practice will cure this. Riding it means keeping your foot on the clutch pedall all the time so that it slips even at speed.
You're gonna hafta drop the entire tranny to get to the clutch, pressure plate, and even tho throwout bearing/ slave cylinder.
its not the baring, its the transmission. its got very old gears.
