Driving in 5th gear tach started jumping engine roaring, shifted to 4th mile later stop sign, shifted to neutral, shifted to 1st nothing, 2nd, nothing same 3rd, 4th, 5th, reverse, wouldnt move ,sounded...
when the clutch is not depressed, the transmission is fully locked to the engine, thus no movement between the engine and transmission should be felt. what did the clutch pedal feel like? what year is your vehicle? have you checked your trans oil lately? with your first sentence it sounds like the transmission is jumping teeth, causing the engine to freewheel and your car to jump.
If you feel comfortable enough to take your transmission out, then drain it, disconnect all of your linkages and hoses, take out your starter, support it with a floorjack, disconnect any crossmembers now, then unbolt from the back of the engine, dont pull it yet, disconnect the four bolts holding your flywheel onto your engine from the front of the transmission, then roll your transmission straight back away from the engine. make sure your flywheel doesnt fall out ( it should weigh between 20-40 pounds for a manual transmission and be very sharp).
once on a table or place you feel comfortable working on the transmission, slide your flywheel, clutch, and pressure plate assembly straight out of the front of the transmission. the friction matierial on a new clutch is very thin but if you see that your clutch is worn to the point that you cannot see the vent grooves or that the rivets are hitting your mating surface of your flywheel. if any of these is the problem then replace the clutch wheel and have your flywheel ground or replaced (watch out for asbestos dust off of the clutch, soak with water before dissasembling) (if need to replace your clutch, always remember what side is the rear and what is the front of the clutch (take pictures if need be) your pressure plate (the wheel with the springy fingers in the middle) (what i think is wrong) should be able to support your weight on the springs (180-200 pounds) with minimal give to the spring, if it gives alot then replace. also check to see if the bearing on the shaft, has play in it. this is the throw-out bearing (ironic when you need to throw it out) if it has play then replace and get a new one. for good measure inspect the magnet in your oil pan when you drain the transmission for excessive metal shavings, and if your feeling brave enough look at the gears (either through your opening in the oil pan or by taking apart the gearbox portion of your transmission) to check for broken gears, worn gears, anything other than shiny after cleaning with brak-kleen or other solvant. if you find damage here then message me again and i will walk you through taking the gearbox apart.
Hope This Helps!
