Not really and didn't notice revs increasing (not that you do ).
More like "hunting" between gears.

Gearbox itself is totally dumb - No electronics in there. All the intelligence is in the Gearbox ECU. It basically just opens and closes vales in the gearbox to more oil around and shift things.

The ECU's arent coded, and can be swapped straight over.

Speed limit restriction will be on the engine ECU.

Adjusting the shift points is down to the Gearbox ECU

A little hiccup like this doesnt sound too scary. You can catch most Autos out if you try hard enough. I'd be more concerned if it was thumping about driving in a straight line at a fairly constant speed....

I'm a long way from doing that, but with "used" prices at £100 to £150 it may be worth trying some time. It looks to be a relatively easy swap as it's on top in the ECU box.

There seem to be lots of identical-looking gearbox ECU's with part numbers starting 4D0 927 156 but various suffix letters.
Presumably the suffix is critical, anyone know what my late PF S8 needs, or do I need to "open the box" to check?

Well the thread I started separately on this subject has revealed the answer.
It seems I (most probably) have an ECX version 5HP24A gearbox and I definitely have a 4D0 927 156 BL TCU (confirmed by VCDS).
Member ainarssems said the BL is for use with ESP (which I obviously have) and there's a BM version for non-ESP.

Since having the gearbox fluid/filter change I've had no more thumps, just the odd "twitch" and since the gearbox coding change from 00101 to 00111 (which I think turns off DSP) it's been even smoother though I have had one "twitch" today.

This was going up a steepish hill from a junction, fairly straight, probably in 3rd heading for 4th and again felt as if it couldn't decide what gear to use. Following that I tried to recreate it in "tip" mode and couldn't - it wouldn't misbehave when in any gear even with a heavy right foot and forced changes up were all fine.

The only thing I haven't tried yet is to see whether having ESP on or off changes anything when in Drive. Given that there are ESP and non-ESP versions of the TCU it's just one more thing to try. Also most earlier occurences have been in situations where ESP might just be "considering" doing something.

Given that I've been told the middle gear changes have been "tweaked" (though I have no details of how) I'm still leaning towards trying a replacement TCU when other options are exhausted.

Any and all suggestions welcome on what to check and how.

Hi I know this was years ago but did you manage to sort it? Mine has the exact same problem but I can't seem to find an answer for it?
Thanks in advance

No, I sold the car (to IT on here) who kept it for a while because it was "very interesting". I think it was scrapped long ago.
