clutch is on its way

clutch is on its way and needs replacement

Hi Kristopher, A shudder from the manual transmission is usually caused from a defective part in the clutch assembly. It could be caused by uneven wear of the pressure plate (clutch cover) or wear on the clutch plate boss (The center of the clutch plate with the springs or rubbers which absorb the torque when releasing the pedal) A shudder can be generated from a defective engine or gear box mount, worn CV joints or spiders or a loose bell housing. Start with the last suggestion and work backwards as the clutch replacement will require the most work. If the clutch assembly has been replaced recently, and the parts available are of the same quality we receive where I am, you will need to do the job over. Regards John

vauxall zafira 1.8 04 plate auto . problem when on starting it doesnt let me rev and jerks on take off but after 2 minutes it runs fine worried incase start of bigger problem any ideas would be great.

There isn't a car out there that likes to be put in drive as soon as it is started. Mine especialy. I give it at least 30 seconds to warm while I am adjusting evrything and away I go. Runs like a champ. Let it warm up for a couple of minutes from a cold start.

Computer stops free rev for overrev protection. Does this happen when driving?

Most likely nothing mechanically wrong in the gearbox but check the transmission fluid level and top up if low. Also if low, check for site of leak to remedy it. Judder says to me 'imbalance' or an under damped spring. Does the judder emanate from one end (transmission) or one side (wheel) predominantly. Has the judder manifested itself just on its own or is it after having had some work done to the car.
Check wheels for balance - could be a balance weight has been lost, at the same time check the action of the shock absorbers. Check the rear engine/gearbox mount for integrity; its towards the rear of the gearbox and sits on a transmission tunnel cross-member . Now check the front prop to gearbox doughnut coupling, then the central bearing and finally the rear prop to differential doughnut coupling; all should be sound. Signs of splitting of the rubber around the bolt mounts in the doughnuts or a lot of lateral play in the central bearing are indicators for renewal.

Chances are they did not resurface your flywheel OR replace the pilot bearing.

run scanner for trouble codes, some auto parts stores will do this for free

Sounds like you have an electrical problem. I think it would be an idea to let an expert have a look at it even if they only diagnose the problem and you conduct the repair yourself.
