The wife took the truck out on the highway and said that she couldn't get up to 65mph in 5th gear. Dropped down into 4th and got back up to 65. When she got to some real small hills, she lost power but the engine reved up when she hit the gas. She slowed down to turn around at an approach on the road and one she stopped, the pickup wouldn't move. It reved up fine. Shifted between gears fine but wouldn't move. Once the truck was towed home, I looked underneath and there is some fluid around the transmission case where the drive shaft attaches. I had her hit the gas and let out the clutch and the drive shaft turned approx 1/8 revolution. The engine sound fine, It didn't stall at all, She said she didn't hear any clunking noises. She said that it just started losing power until it eventually wouldn't move anymore. Any suggestions as to what could be the problem?
May be a bad rear end, Gear in rear may be broken check rear. Good luck and thanks for using FIX YA

This might be a valve timing offset, that when you change gear your valves become ofset from your pistons and they might hit, or it might also be your crankshaft hitting your oil pan. either wich way this might be a serious problem.

wierd not normal. are you sure you have eased off the throttle enough just before you dip the clutch, diesels can lag slightly, is it a turbo? turbo could create even greater lag

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!
