Gear Change Difficult - 24V-V6-2.5-Manual
« on: 04 September 2012, 11:19:32 »

Hi, had this for about a month, and getting worse.

Finding it difficult to change gear, wondered at first whether it needed a new clutch, but as yet have no clutch slip or odd reving associated with clutch wear.

Always had a minor-slight difficulty engaging 2nd gear, but now 1st is effected , possibly 3rd.

DId think about adjusting gear linkage first, but needs some special tool km631A - or is there another method without tool.

Looked on forum for related issues, but could not find any.

Any help on this is appreciated

cheers

Agree with that  :y

There is a sight / filling point on the side of the manual box.
The oil should be upto this hole when you un screw the plug  :y

and its easy to drain and a pig to fill - I'd suggest a metre of pipe fed from engine bay and a funnel, pour away easily then

I had the same problem with my manual 2.5 about 6 months ago...difficult to get in gear and a few weeks later the clutch would slip occasionally, depressing the clutch pedal a few times would restore normal operation for yards or miles. Asked on here with no joy so decided to inspect the clutch...found the pressure plate securing springs had started to break up ...i think by this time only one was still connected...a new clutch cured it

Emptied old oil out - measured and came to about a litre, halfrauds says 1.2, so not far off full.

Re-filled with new - made no difference, so I think I has to be the clutch -

What manufacturer is the original clutch, does anyone know - Borg & Beck ect.

Will look at the instructions on the forum

cheers

If the linkage between the gearbox and the gear lever slips it might make selection difficult.

Not difficult to adjust IIRC :-\ just a hollow tube clamped to a serrated shaft out of the back of the gearbox. If it is loose you may be able to see were it used to be? If it isn't loose then it probably isn't the problem.......

First things first mate, is the clutch slipping ?
Can you slip the clutch with the handbrake on ?

As for the DMF, unless its being really abused imho they are pretty bomb proof.

If the DMF is on its way out, you normally get a kick or judder when you take up drive.

I shopped around a couple of years ago and got my hands on a Lucas clutch and slave for just under 200 quid but if I was you, i'd be tempted to pull the gearbox off and have a look at the friction linings before I spend the money on a clutch incase its the gearbox itself thats breaking down.

Just to add, most garages will demand that you change the DMF even though it may be ok just to cover there arse with the clutches warrenty  ;)
