Rpm vs Speed, what do you do??

I'm running a be3 standard 205 na diesel box on mine and if memory serves me correct is has the gearbox code on the near side of the box where you fill the oil from the side of the gearbox (first box I've worked on where you fill the oil from the side :z ) I'll have to check but I think a quick look under the passenger wheel arch it's visable but it might only say the series like be3 so don't 100% believe me on this lol
