cold shift behavior
Is it normal for a 5-speed to hardly be able to shift into 2nd when the tranny is cold? I'm using Swepco 201 and after a couple of miles the shifting smooths out and it's perfect when warm. But 2nd gear just doesn't want to engage when first starting out. It doesn't even have to be a particularly cold day either.

Never heard of Swepco but the oil definitely makes a very big difference to the shift characteristics especially when cold. Where I live we never get to freezing point but when I first bought the car it wouldn't go into reverse in winter to get out of the garage. I would have to put it into reverse (with difficulty) before starting the engine. First to second was difficult too. Changing the oil to Mobilube 1 synthetic transformed the box, it feels like a new box altogether now and when I drained a sample off three years and 20 000km later it was still clean.

My car feels the same too. This issue has been brought up over the years and seems to be common for the 5-speeds. I just shift from 1st to 3rd until the transmission warms up.

Mine is the same way, hard to shift into second until it is warm. I just start the car, let it warm up for a few minutes befroe driving off. Makes a little bit of a difference, doesn't take to long to be able to shift into second after that.

One common cause of hard shifting is a dragging clutch, usually caused by either air in the hydraulics, a clutch disk that hangs on a worn center shaft, or a maladjusted center plate on the twin-plate unit.

I noticed mine was a little tight going into 2nd from 1st when cold so I changed to Red Line it is a little better but not much. I also changed to Devek short shifter.

VERY NORMAL ..... with Swepco.
When I bought my S4 years ago, it would feel as if 2nd was gated, locked-out for a good 5 seconds before it would enter 2nd on a cold morning (not that cold here). But when I drained the blue stuff and replaced it with Mobil One Synthetic, the problem magically disappeared as if the box was brand new. I've driven on the same clutch and gearbox now for 6 years and I recently looked at the clutch which is still in excellent shape. I drive hard and my car puts out gobs of torque on the dyno (measured 299/299 to the wheels at one point) ..... So .... don't know if you'll have the same result, but for me I will never come near swepco again.

I tried Swepco many years ago with the same results as everyone else.
Almost impossible to shift when cold.
Switched to Mobil 1 and the first shift when below freezing is a little balky, but then good.
BTW, the Mobil 1 that I use is Mobil 1 75W-90 Synthetic Gear Lubricant.
The bottle says "Exceeds performance requirements of API Service GL-5". Porsche recommends GL-5.
