Renault UN1 Transaxle

Renault UN1 Transaxle (UN1-04)
See Renault UN1 google doc for more info.

The recommended oil is ~3 litres of Castrol TAF-X 75W/90. Due to the fact that this is not available in NZ and that many people using the UN1 on the track use Redline MTL, we will do the same (buy this from BNT).

Using 2nd, 4th and 5th we get the following overall drive ratios and performance figures.

However 5th gear is the weakest in the box. http://www.un1.co.uk/Upgrading%20the%20UN1.htm (wayback machine link)
