Drained and filled my 5-speed gearbox earlier this week. I used full synthetic Walmart Supertech gear lube 75w90. Sorry to say it does seem to be tougher/notchy to shift in cold weather when first starting out. It was about 40 degrees today when I noticed it.

Anyways, what is with Porsche saying 11mm below the fill hole? I tried the little bent paper clip routine and had a hell of a time getting it right. I think I got it but not 100% sure. Since 11mm is hardly anything - anyone ever just fill it until it spills out? Catastrophic failure??? Why didn’t they just locate the hole 11mm lower?
