nope you got an automatic gearbox... but you might want to check when the oil and filter from the box have been changed last... if you can't find it's been done might i suggest you do so ASAP... note it's not cheap as the oil is a special blend that is extra heat resistant, made so it allows for a certain amount of slippage and keep dirt and shavings suspended so they can reach the filter to be seperated and stay trapped in it... and afaik the s-tronic oem oil and filter change recommendation is at every 40k, but best to be done at around 30 to 40k to prevent problems ike you have now.
