Renault boxes usually have round metal tag on one of the casing end studs which have the type of UN1 stamped on it. Check against the chart for the box type, source car. Gear and final drive ratio.

Renault Espace V6(old model) had depending country the version UN1-04 or UN01-08

the 04 version has shorter ratio (3.89)than 08 (3.77)box so a little les top speed but better acceleration.... it's a game of finding .... the best compromise option for you in terms of gear ratios and what yourself want or hope..

Never heard of a UN1 012. Can you get and post a clear pic of the tag. My Renault UN1 list is the same as Paul's.
Cheers
