high rev when accelerating 700 1989

Hey everyone I need your help desperately.
When I am in gear(i have a manual M47 transmission), and I go to accelerate more than a tiny bit, my car gets really high revs fast(like 3k). Then when i stop accelerating the needle drops fast back to normal position. I am going to do an oil change cuz the oil is starting to get dark and somewhat burn. Please help me in some way... maybe i need to clean some stuff or do some small or easy repairs? PLEASE TELL ME ITS NOT MY WHOLE TRANSMISSION!!!!!!

Thanks alot,
Jeremy

    Sounds like a slipping clutch. It starts in higher gears, and after a while it will happen in 3rd & 2nd if it gets really bad. While driving on the highway in 5th, if you push the gas down quickly and the engine revs, but the car doesn't accelerate, the clutch is slipping.

    Plan to have the flywheel resurfaced when the clutch kit goes in.

    sounds like a fryed clutch my friend....here is the classic test ...start the car moving using 1st gear and get up to about 10mph....then skip all the other gears and place the car into the highest gear...floor the gas pedal. If the clutch is working well the revs should sharply drop off and the car should lugg and chugg...and possibly stall. If your clutch is fryed the revs will hover inplace or even rise. good luck

        honestly, this is not what I would call a very complicated repair, but it is out of the realm of most home mechanics. this can be accomplished at home and given the fact that this is a RWD car it is not that bad, but unless you are very experienced or very good at reading technical manuals, I think that given the time and effort involved that you would be better off paying for a pro. I am by no means a professional (whatever a professional is around my way is subject to debate) but I have been knee deep in the guts of cars since i was about 10. I can do this repair in around 4 hours (if all goes well) but i have seen this take others days....(and then it was never really right on an older non-self adjusting set-up). usually when these things go, it is a wear issue. clutch linings are considered consumable in the same way that break pads are and tires are. I did have a car once that exhibited similar symptoms and it was not a warn lining, it was a defective slave cylender...(i think unlikely here) the higher the milage the more likely i am to say that this is a lining issue. check FCPGrotton.com for a price. I also hate to bring up the fact that the majority of clutch wear is in fact caused by improper use...thats right bad driving. My last manual tranny vehicle lasted 276k miles on the original clutch. my girlfriend's on the other hand lasted less than 20k miles...do you find yourself resting your toe on the clutch pedal while moving? or do you just hover your foot above the clutch pedal? Either one is certifable as CLUTCH ABUSE....DO NOT DO EITHER! these are improper technique and are to be scolded. even if you drive in a lot of traffic just take your left foot and place it on the floor or dead pedal...before i fly off the handel...I am sure that you aren't the first owner of this (clutch) and didn't cause this...but keep my comments in mind. good luck

          do I need to replace the Clutch Disc and the pressure plate or can I just replace the clutch disc and use the old pressure plate???

            Really it depends on the extent of the damage. most of the ones that i have dealt with have only needed a clutch lining, and possibly a throw-out bearing...it just depends. sorry for the weak answer. I would find a good shop and have them do the job, or at least get an estimate so that u can gage how much it is worth to you to do it yourself.

                Here's a picture of a complete clutch kit:



                The "disc" or "lining" will need to be replaced for sure (bottom right). The other components shown here are the pressure plate and throw bearing.

                  ok thanks guys. I just bought the kit from FCP Groton for 145 bucks. not too bad. I also bought the rear main oil seal at the same time since this can only be repair when transmission is off. I should get the kit today or tuesday and my school's automotive technology will spend most of the day doing the work on my brick for free! Good thing I play football with some of the kids.

                  Thanks for all your help
