Looking for advice

Hi,

joined forum to try and get some advice re my daughters car. She has a 2002 1.0 16v manual SE.

Falls out of 5th gear. Any ideas please.?

best to check the rear mount for play kev, if its a bent selector fork tho it would be expensive to fix (and the coilpack g/boxes fetch crazy money)
 
Thanks, went to a garage and mentioned these pointe, they said, nothing wrong externally or fluid so must be internal. Quoted £300 to remove and refit plus whatever gearbox specialist does. They did say as it was intermitant and not all all the time could carry on driving until repair can be finamced !
 
Thanks i am not much of a mechanic!but will have a look It only happens in 5th, have you heard of this before in the MSC? It is a low milage car, owned by a 'granny' previously
 
when selecting gear, the normal process should be:
  1. clutch fully disconnects engine from the input shaft,
  2. gearstick linkage system moves selector rod, overcoming the ball/spring holder,
  3. rod moves selector fork & synchro hub towards the gear cog,
  4. synchro matches the synch-hub and cog speed,
  5. once the two cogs match and splines align, the hub teeth is allowed to slot/engage fully into the gear cogs female spine. the ball/spring mechanism holds the selector rod in the forward/neutral/backward position
  6. clutch released,
  7. torque transmitted through the selected gear jams/locks the synchro-hub against the cogs female spline preventing it from slipping out

so first I'd check if the clutch is fully disengaging.
a dragging clutch will make selection harder to fully engage. if the gear is only partially inserted into the cog it'll likely slip out.
bite point should be bout 1/4 - 1/2 way up. adjust the thumbscrew at the end of the clutch cable under the battery tray to alter the bite point.

next is check the gear linkages for loose nuts, worn slack bushes.
slack linkages may not allow the gearstick to move the selector rod far enough to engage & lock into gear so it slips back.

select a gear and apply light force back into neutral to see if the selector rods ball/spring is holding/locking it in place. if it slips back into neutral with ease, the ball/spring latch maybe stuck,broke.

Thanks, everything looks ok. Strange thing is it doesnt happen all the time and ony in fifth. Couple of days ago she drove 20 miles up M27 in fifth and it popped out, put back in and all OK.

i am baffled. Garage said it wil need the gear box out to have a look, but she dioes not have over £600 instantly and it can goes days without it happening. It did have a new clutch about 6000 ago and was fine. Only done 58000m and owned by old person previously ( which might explain the clutch wearing out)
