I understand this is a very old thread but can anyone else confirm changing oil makes a difference in crunching gear changes?
I bought my 200 cup about a month ago, at 75K miles with gearbox 'rebuilt' at 68K. The fact that gearbox was reconditioned / rebuilt was one of the major reasons for choosing this particular car. Gearbox had been very sweet and smooth until this evening when the 3rd gear began crunching during the evening session at Brands Hatch. Being my first track day after 9 years, I was a naturally excited and drove the car a little hard but did not do anything stupid, missed gears etc.
I am really struggling to understand how a very recently reconditioned gearbox could give up on one of it's syncros in less than 1.5 hours of hard driving (and that's with taking regular brakes). Do you reckon the job was not done correctly, because if not, this could as well mean gearbox reconditioning every 5-10 track days even if I change gears more gently!? In comparison the last car I tracked, a 2001 Impreza WRX (again bought 2nd hand and gearbox known to be the soft spot) took 3 years of constant beating before giving up on 3rd and 4th syncros. And that was when I was 25, living in Istanbul, driving like a race driver (!!) non-stop.
Perhaps it'll be fine once properly cooled down (tomorrow) and with new / better oil?
