Well I just picked me up a ST170 1.8l Corona as a daily driver.. MINT body and only 164,000k's (its a 1988) but upon driving it home along the motorway it kept poping out of 5th gear

though sometimes it would hold it fine

Could this be a linkage problem or something? The thing is that at 100km/h the corona is reving at 2,500rpm in 5th and only 3,000rpm in 4th gear at 100km/h so when it does pop out of 5th gear I can still comfortably cruise in 4th at 100km/h.. its just a bit of a hassel. ALSO.. dam speed chime at 105km/h AAAARRRRGGGGHHHH!!!

so will have to take the dash out and remedy that!
Any advice on the gearbox problem would be most appreciated!
