Hi Sven,

i've attached a sheet that shows the logic of the 986 transmission number. So you should recheck your transmission number first.

Transmission types and number by model years (geman model years) - see attachment.

If second gear doesn't get in when transmission is cold, in most caes the front motor mount is worn (had the same problem) and poeple don't use the right transmission oil. There is a special oil from Shell that should be used with that 6 speed transmission. Any other oils in general cause problems. Problem is that you can not buy it in Germany in sizes less than 20 litres. So i did a group buy.

If the 2nd gear doesn't go in because of worn front motor mount and wrong oil and people force to get it in, transmission will be ruined within short time (Synchronringe). So it starts to pop out. Search for the detend solution Gelbster postet, which can help if the 2nd gear isn't fully ruined.

Changed Motor Mount @ 95k

If you want to replace the gearbox also replace the front motor mount and also check the gearbox mounts.
