Transmission problems

Question, anyone else has had gearbox issues with his/her CRD? I have a 2007 2.8, 6speed manual, 82000km and when the engine is cold, no problems, once it het warm, the gears aren't going that smooth anymore. I changed the gearbox oil last week with Ms 9224 as the dealer recommend . The clutch does not slip, no cracking sounds.. Just harder to get it in the right gear.

Sounds to me like the clutch is not releasing properly.
Check the fluid level in the clutch master cylinder.
I suspect that the clutch master and/or slave cylinders are leaking.

Can you tell me where I can find this cylinder ?

Here in the states, there are no CRD models with a manual transmission.
So I have never even seen one.
My best guess is that the clutch master cylinder is under the hood and looks like a small brake cylinder.
The slave cylinder is probably inside the transmission bellhousing.

Ok thanks for the tip, I'll have a look. But if it would be leaking, I would have to see some drips here and there, right ?

You might see drips, you might not.
Sometimes the internal seals will go bad and make it so it cant hold the pressure but never drip outside of it.

If this happens only when cold, it's the syncromesh in the gearbox that have stiffened up. it's a common problem in 5 & 6 spd Jeep gearboxes (see XJ & TJ). You have two solutions, change to oil again to the correct one by Mopar or ATF 4 for the Auto gearbox that sometimes does the trick. Mine plays up at temperatures below 13C and is a real pain through the winter until be box has fully warmed up. After it's okay. I even had the gearbox rebuilt by Jeep 5 yr ago and now we are back to the same problem after 70K miles ( I have now 140K miles on the clock).

That's the thing, when it's cold, no problem, only when it's warm and need to shift a lot..

Looks like you have the opposite problem I have, cold fine , warm hard to shift.... I guess it might be linked to the oil you have used then, not enough lubrication, I would suggest to change oil and make sure to use Jeep oil.
