HARD shifts...

[Stephtell]

Right then, 2004 CTT:

The car runs fine and up- and downshifts in manual mode are fine.

Up- and downshifts in auto mode are fine as well, extremely smooth, but under heavy acceleration upshifts are HARD...

You can feel a hard 'jerk' as it bangs another one in...

No errormessages, no strange behaviour, car still runs fine but holy hell...

Is this normal? I would assume not but then again, no errors, running fine so...not a problem?

Any and all advice much appreciated!

Valve body.

If it is the valve body I would expect to see fault code(s) with Durametric, a Porsche PST2, or Porsche PIWIS tester.

Very dirty fluid and/or a clogged filter can cause similar problems.

[Stephtell]

Hmm...I could change the fluid myself BUT I have no way of heating up the oil and checking level with a computer or something...

Can I just drain fluid, replace filter and fill with the ammount that drained out?

you can do that or you can measure the fluid temp with an IR gun or thermometer.

As for heating the fluid, you will do it the same way dealerships do it.....turn the car on and let the tranny warm up itself.

Hi mate,

Thanks for that but please remind me, measuring the fluid temp has to domwith measuring the correct level right?

But it doesn't have a dipstick for the gearbox does it? So how would I know the right level has been reached?

[deilenberger]

It uses an overflow tube - that sticks up in the sump. As the oil heats and expands the excess that rises above the tube drains out. At least that's how I understood the manual explaining it..

[Stephtell]

Ah! That makes sense! Should be an easy though somewhat messy job then! :-)
