  • [Corsa C] have no gears


  • #2
    I be looking at the drive shafts , if you have lost all drive it should be fairly obvious.
    I did have a 02 plate a few years ago that lost all drive , fitted a new clutch still the same (well pissed off) it turn out to be the large diff gear in the gearbox where the driveshaft fits into from both sides.
    The car had been mapped by the previous owner, and probably to many fast pull aways.
    Hope you get it sorted.

      many thanks for the info mate

      could you please explain what you mean by, "i'd be looking at the drive shafts,it should be fairly obvious ?

      i looked at the driveshafts but nothing jumped out at me,there were no damaged seals,leaks,metal shavings,etc,also when i put the car in gear,the shafts turn the same as if the car were in neutral

      PLEASE excuse my ignorance,but ive not had any dealings with front wheel drive,driveshafts...

      i learned most of my mechanical skills doing up rear wheel drives in the eighties,mark 1 and 2 escorts and cortinas,chevettes,etc,fitting 1600 crossflow engines,Corsair 2000e gear boxes,with lsd axles off 2.8 injection Capris

      can i ask,why did you replace the clutch when you lost all drive ?

      can a clutch stick in the on/engaged position ?

      ive smelt no clutch burning,and heard no clutch slipping noises

      also if my clutch was done,i'd be able to start the car in gear,and it would move and drive in the chosen gear

      i understand what your saying regards the large diff gear in the gearbox,it may no longer grip the driveshafts,so they will no longer turn

      after reading your info,i'm swaying towards getting a gear box from the scrap yard,with it's accompanying gearlinkage,that way i can attach the new linkage at the gearstick shaft,at the clamp that takes a T55 torque to tighten/slacken,then pop my own driveshafts into the donor box,only if my driveshafts look undamaged when i take mine apart,if mine are damaged,i'll take the driveshafts that came out the donor box

      thank you for taking the time to reply to my post

        Hi. A few thoughts, highly theoretical. Disclaimer. My knowledge and experience is also dated and limited, so please dont go to any expense based on what I have said.

        Some may not apply to Corsa's or be highy unlikely or impossible.

        My only related experience of front wheel drive engines is bunging 1980's Honda civic engines and gear boxes into rear wheel drive trials cars -giving double final reduction, the civics own and the live rear axle. The car would start off in 4th up a 45 degree slope!Never had to dismantle the civic transmission though apart from clutches.
        IDEAS
        1) The flywheel is loose on the crankshaft and spinning . Not likely. 2) clutch worn out. Again unlikely,with no slipping or eau de ferodo. 3)A mechanical fault is causing the clutch pressure plate to jamb in the disengaged position. Would probably only happen as you change gear, not suddenly while travelling on the motorway. 4) Gearbox problem. Although the selector rods are moving, are they in correct register and are the gear clusters moving as they should. Could a thrust washer, spacer or bearing/bush be allowing the gears to move and float out of mesh. 5) Problem in the differential, or the drive shafts. Not sure what this could be, but the car pulling to the side at one point could be indicative. If a wheel loses traction on ice etc the diff stops the car moving at all. Same could be happening here if one drive shaft is spinning but not transmitting torque, eg stripped splines or whatever.
        I too would be inclined to check the drive shafts first. If you end up replacing the gearbox on a speculative basis it would be a good idea to check other parts while its out.

          WOW 2.30 in the morning either you work nights like me or can't sleep because this corsa is keeping you a wake at night lol.
          I reconise all of those vehicles, my first car was a mrk 1 capri, most be about the same age .
          What I ment by it being obvious is that with the car in gear and the wheels on the ground you should not be able to turn the Driveshafts .
          Take the driveshafts out first and examine them .
          Just a tip on that, slacken the large hub nuts off first before you jack the car up.
          I've got ramp and a big air gun , don't know how or where you are doing it .
