Humour me - by removing the factory radiator (losing the transmission cooler), and then installing a 11"x7-1/2"x3/4" transmission cooler, along with about 800mm of extra hose total, surely the system would need more fluid?
At the moment the dipstick doesn't show any dark fluid on it, which is exactly what is draining from the trans cooler hoses, but appears to have a heap of fluid on it - up to the little s bend in the dipstick.
Is this a problem with topping up from the dipstick?
I've read on the G35 forums that the dipstick is pretty hard to read, but if anyone has any advice I'd like to hear it.
