Hallo Raimund,

did you check that manual behind following link:

www.vaglinks.com / Docs / VW / Passat / B5 /
ZF.com_5HP19_Automatic_Transmission_Repair_Manual.pdf

Just remove all spaces from line above.

There is also a catalog available from Transtar Industries showing
rebuild parts for 5HP19.

www.automatic-berger.de / mediafiles / Sonstiges / Transstar%20neu /
Import / ZF5HP19 / ZF5HP19.pdf

There are other pages for this autotrans available as well. No idea if
this could be helpful for you.

Regards
Helmut
