Hi I have recently been on a long drive in my cmax 04 2.0tdci and since then I have a problem....

Put it in 5th and somewhere between 60 and 70 mph there is a crunching noise and its asif the gearbox is not engaged for a second as the revs drop. I can drive through it and into 6th fine

This dosent happen in 6th gear at all even through 60 - 70 mph

I have also noticed if you creep up in 5th it dosent happen only with hard or moderate acceleration.

just to add the clutch has been done before although occasionaly I get a tapping noise from the gearbox when the clutch is pressed - I assumed this was maybe the clutch release bearing or something but this is very occasional and not recently.

I would appreciate any comments or suggestions If you guys know anything about this.

thanks for reading!

Sounds like it could be the synchro?

For now I am avoiding 5th as im still away from home... no tools! My knowledge on gearboxes is minimal to none so do you know if there's any way of confirming this? As I dont want to remove the box unnecessary but I suppose its coming off anyway haha

Thanks for replying

Only way is to remove the gearbox an strip it down once youve made sure its an internal gearbox fault

True, A fair bit of reading for me then before I take the box apart - and a spare bit of cash in case it goes wrong I could always get a 2nd hand or refurb.

I suppose it could be the linkage but I dont think its going to be that kind to me!

Its a bit confusing because it shifts without issues and this is only in 1 gear at a certain speed.

Cheers

Do you change going into 5th at 60-70mph?

No I put in 5th at about 50

Check everything before you rip the geaebox out. Like driveshaft etc. Anything thats rotating.

Best thing to do is to get it on a 2 post ramp and get someone to get to the speed in the air and see if you can pin point it ( strongly advise not to do it on car jacks etc)

Sounds like a good idea ill be home by sunday should get it done in the week.

Although earlier I was forced to put it in 5th on a dual carriageway hill and it sounded alot worse happened at 55 then again at about 65. So ill deffo stay away from 5th untill i find the problem. Thanks for your input mate
