Hi all

I was curious to know where the speedometer or odometer sensor is located because i suppose it is failing

since a few weeks, the odometer doesn't increase km, it shows speed but it does not count km, no total , no trip, both are stopped.

curiously ,after some hammering in the exaust system, strangely the odometer started to work for 80 km then stopped again, so I supposed that there is a sensor underneath somewhere in the gearbox that is failing
but after close inspection I can't see any sensor in the gearbox.
Can someone tell me where is located or where I can download a copy of a workshop manual to learn more about my car?
I need also check the gearbox oil level and a manual or advice will help with location of level plug

is a 4.2 ABH with automatic transmission

thank you in advance
