I had the gearbox oil changed in my 99 Type RA a couple of months ago. The general notchiness improved a lot, but when the car is warmed up/hot, the shift up from 4th to 5th is awful. It graunches and grates when going in. If I double clutch it, it goes in fine. And its fine when the car is cold.

Is this down to bad 'hot' performance of the gearbox oil?
Do I maybe need thicker gearbox oil, to compensate for the sychromesh getting worn?
Also, could it be crap clutch fluid that causing it?

The guys who service it used Castrol SAF-X gear oil. I mentioned Syntrax, but he said it wasnt good enough for the hi-end, quick-shift gearboxes...
Not sure what clutch fluid they put in though, but is it likely to be this?

Can anyone advise?

Many Thanks

My MY 95 WRX was awful when i first bought it when gearbox got hot ie motorway driving I thought the gearbox was on the way out 4th to 5th, 4th to 3rd so i bought syntrax by castrol and as if by magic gearbox turned silky smooth 10.000 miles since oil change and still feels good very particulr about il in gearboxes are scoobs
hope this helps
