Does sound like slipping clutch , you may not get all the symptoms at once , the slipping usually starts first then the hard gear change etc cant think what else it could be , may have oil contamination on clutch plate this would cause the slip , crank seal ? i think your going to have to drop the box and have a look keep me posted if you wish

It's possible that the clutch just needs to be adjusted, you clutch pedal should have an inch or two of free play, that is, it should not disengage for the first inch or two the clutch the pedal is depressed. If free play is insufficient, adjusting the clutch will fix it -- as long as you haven't driven it like it is for too long.

Clutch problems tend to snowball quickly because slippage causes excess heat, and excess heat causes premature failure. Failure in turn results in worse slippage, it's a vicious cycle. A slipping clutch will cause the clutch disk to glaze before you know it. Once glazed it will likely continue to slip even after proper adjustment.

If there already is sufficient free play, your clutch wear parts are just worn out, the friction material of the disk is worn down and/or glazed and/or the pressure plate's spring steel has fatigued. For any of those problems the remedy is the same: new clutch. Always replace the pressure plate, disk and throw-out bearing at the same time, if one has failed the others are on the verge of failure.

Why Is My Automatic Transmission Slipping? If you have an automatic transmission and it "slips" while you are driving it-that is, the car engine revs without the power going to the wheels-the most common cause (though not the only possible cause) is low transmission fluid. If the slipping is caused by low fluid, it will get worse as the transmission gets hotter.
Why Is My Manual Transmission Slipping? A standard ("manual") transmission uses fluid too, but leaks aren't a common issue; a standard transmission could lose all its fluid and never slip at all, though eventually it would lock up while driving down the road. If you have a standard transmission, and it's slipping-the engine revs but it doesn't transmit power to the wheels-the problem is usually in the clutch.
Further down in the article I discuss how to diagnose this problem.

WHen under load the motor revs up and it seems that the Clutch is slipping, it has 100000miles and I suspecting the clutch or the high / low range might be messed up, its a 4 plus 3 manuel transmission.


If it feels like the clutch is slipping, chances are it is. If there was a problem in any component that has internal gears, you would have grinding noises. Gears cannot slip. As the clutch wears more you may hear grinding when you try to change gears but that is because the clutch won't fully disengage so the gears are spinning too fast to shift properly. Before that happens, have the clutch replaced.

I have an 1989 GMC Sierra K1500(4x4)5-speed. grinds when going...


It may be the transmission input shaft bushing or bearing, located in the rear of the engine crankshaft, in front of the clutch assembly. If the bushing or bearing is dry (needs to be greased), the input shaft will still try to turn with the engine rpm, even though the clutch pedal is depressed. Also, the clutch disc may not be fully releasing, which could possibly be corrected by adjusting the clutch pedal linkage. good luck

1992 GMC Suburban not shifting into OD, Transmission Modulator?


The shift down linkage on the carburetor below the gas pedal cable might need to be adjusted to increase the hydraulic pressure on the internal clutch plates in the transmission it shows you how to do that in a car manual.

Engine revs and i am only at 35 miles per hour. before this the engine was revving with loss of some power at pedal.


is this car automatic transmissiom or standard,if auto does the transmission fluid look brown and smell burnt,fluid should be red,if it is brown and smells burnt,likely a transmission failure,if car has a standard transmission it sounds like clutch could be slipping,if its a hydraulic actuated clutch,there could be a problem with hydraulics hanging up or the clutch itself is worn out

Is it a standard or automatic transmission? If standard, your clutch may be slipping. While driving down a straight road, push the brake while still in gear and push the gas pedal as well. If the engine slows with the vehicle, the clutch isn't slipping. If the engine speeds up while the vehicle is slowing down, the clutch is slipping.
If it is an automatic, check the transmission fluid. You may be low and the transmission is slipping while under load, or the torque converter is slipping for the same reason. You may have a bad torque converter clutch switch, but the computer should have picked that up and made your "Check Engine" light come on.
These are the main reasons you would be losing power going up hills unless your engine isn't powerful enough to handle the larger tires on extreme hills. (It takes more power to turn a larger wheel going up hill since the vehile has to travel further for each revolution of a larger tire. Incidentally, have your speedometer checked. You will be going faster than what the speedo says since you put larger tires on.) Good Luck.
