Gear changing was bad - worse after oil and filter change

I suggest the first thing you do is ascertain EXACTLY which ZF box you have
just looked through our hosts list of boxes for used boxes for sale , and they have a 97 one which they say is correct ...code DRD , which fits a range of audis !

if that IS correct they want £300 , don't know what sort of guarantee , if any ,they offer
it's come off a V6 so probably had less strain

How do you determine what gearbox you have? That seems a reasonable price but I guess fitting is the expensive bit? I just about managed replacing the air blower myself, a gearbox may be a bit beyond me! I will call Vanmatic Monday and see what they say.

Build sticker in the boot or service book tells you the gearbox.

Engine code and gearbox code are on the same line.

well on my transmission line for a 2000 FL it is marked EUT ECH [ spare wheel compartment AND service book ; according to ETKA EUT is correct for D2's from MY 2000 to the end
but what box is it ? probably got to get under and look for a plate ?

ECH is apparently some type of production code

On my build sticker (2002 S8) the line for Engine and Transmission codes are AVP (for the engine) followed by "EUU" and "FBG". The latter is the transmission code as it matches the codes listed by ZF in their (USA) Transmission Identification Guide for the 5HP24:
http://www.zf.com/na/content/media/u...tion_guide.pdf

Which means (assuming the build sticker list things in tha same order) that Oldnick's transmission code is ECH (not EUT) ..... but ECH is not listed in the guide - perhaps a non-USA thing?

Just looked at the Service Manual for O1L boxes in the Tech Dump sticky (RTFM)! and it lists all transmissions and their codes. Whilst there is no "ECH" there IS an "ECX" which, giving the computer type face used for the build stickers could have been misread, perhaps? The ECX has a manufacture "from" date of 04.97 but no "to" date.

Whilst the ZF Tranmission Guide is USA specific, the service manual is for European vehicles.
