Getriebe: Automatikgetriebeproblem ZF 6HP 26BMW 760 li/2005

[Dalibor-zg]

I have a problem with transmition-getribe ZF 6HP 26 / stueck 1068010125 on BMW 760li which I buy last week. I need a help, iff sombody have a shematic -diagram off this getribe??
When I drive between 2-3 gang something hapend inside and transmition-getribe go in "notprogramm".I am slowly going to service station,they put out this transmition and they think that I need "dihtung satz" - ( reparatur-satz?)for this transmition.
In service they ask me for shema-maybe sombody have shematic diagram off this transmition or knows a website where is posible to find??
Car is 240 000 km and just new for me becouse I buy this BMW from autohaus "Polmaxx" in Laatzen near Hannover before 3 days. Bad luck.
When I test this car in Hannover on "probefahrt" only one time hear "clic" when transmition change a gangs - fom up gang to down-but a car is cold and I think that is becouse oil is cold..,only 5 km tested and they guaranted me that is always in perfect conditions like a new....A long story I have and bad experiance off this buy in Polmaxx.....much more than this problem with transmition..
