Dear All,
maybe it is some strange for you to see unusual member on this area with not tipical question what are discussed here.
Firstly my short wailful story when my car stopped amid forest near of Moscow (25 km). It was 05 of December, 19-00 of evening, but thankfully the weather was not cold, about -10 degrees. From this moment I got a dark side for my life on next four months and maybe more.

It is truth in Moscow locate a lot of services which offer transmissions spare parts, but they are very expensive due to terminated market... As a result I had repaired all mechanical parts by way of exchanging these one into the gearbox - but a progress of hits are staying. During some not multiaspect actions (it were changings between of two Valve Bodies on my car) - all involved "professionalists" had common conclusion the matter in the Valve Body is bad. Me personnally had test drive on the different units and has feel not same connections of gears.
So I have a strong with to purchase Valve Body directly form EU. The only moment I am worried about is that there is a possibility of mismatching. Because all service man doesn't present guarantee for a new unit after installation...!!!

The questinos is, if it's really possible that purchased Valve body will not be suitable for my gearbox? And why?
If I will provide a supplier with all the references No-s, can I be sure, that the Valve body is exactly suitable?

For imformation I give here the transpission and Valve body type:

VOLVO V70 XC (Cross Country)
type of engine: В5244Т
Number of engine: 2209531

The reference of my existing module - valve body, sonnax, AW55 - 50SN :
1) First number on the valve body - Casting on the first plate: 9165 Т1
2) Second number on the second plate: 12010378
3) Third number on the third plate: 11310970

GearBox is:
Aisin AW Co., ltd
Made in Japan
55-50SN
9480
897
Serial No. 01BV70028

Does anybody know if the valve body is absolutly standard and I can purchase it for sure? Or are there some modifications possible, and I need to find out more imformation? For me is typical breakdown of part from Sonnax company (Producer of Valve Body for ASIN Warner) - but isn't typical dark situation with a new units installation to my old transmission.
Thank you.
