Just wondering if anyone can shed some light on what this could have been.
Stock standard 2012 FG XR6T MKII, ZF auto, 38,000KM
Rolling over a give way into a 100kph zone I floored it and when it shifted into second gear there was a very very loud bang / thud from the gearbox. It continued to drive fine, so slowed down and floored it again but this time it shifted fine into second, and hasn't done it since.
I'm wondering if I should service the transmission, its only done 38,000KM but is 5 year old oil in there?
