gearboxes

I have an automatic c5 VTR estate but am unable to correctly identify the box: when searching only two types appear for the c5: In my requested documentation from Citroën, states: the box is an AM6B automatic but I cannot find anything about it, even under 'diagnostic' 'transmission' it says BVA AM6. help? The car is an 06 with an 08 engine, replaced under warranty by main dealer. I tried to source by serial number but failed.

4 speeders are a zf unit .. 6 speeders are an aisin auto box. Apparently VERY reliable and no issues useually.

Yep, probably this Aisin:

There should be an ID Plate near the filler hole on the top of the box



My advice if you do have an Aisin Warner TF-80SC, AF40/6 autobox, never drive through standing water, and change your ATF every 40-50,000 miles.

You can read about my experiences with that particular box as fitted to a Vauxhall Vectra here

I now have a separate cooler fitted, as there was always the suspicion that the original cooler in the radiator fitted to the Vectra, was a source of contamination of the ATF with anti-freeze. The cooler arrangements on the C5 may be different/better.
