6th gear syncro problem?

[Tomh94]

Hi guys

So i've recently returned from a european road trip and spent some time on the autobahn. 

 

I've noticed recently that my car occassionally crunches going into 6th gear. This problem became very apparent on the autobahn above about 120mph when the car didn't seem to want to go into 6th at all. 

 

Does this sound like my syncro has gone at all? 

 

Never experienced this before. Any advice is appreciated.

Probably the fluid boiling due to the higher than normal temperatures on the autobahn, or perhaps the CSC on its way out.

Hi Alex

 

Cheers for that, the crunching sometimes happens in the uk as well with normal driving speeds, however a fluid change might be easier than the csc so i'll maybe try that first!
