Hi All I've got 2 problems which have developed over the last month or so and want to check if they are possibly linked;- Speedometer, which runs off the gearbox (1992 Supersport with type 9 5 speed), has started to waver up by circa 5-6 mph at up to 60 mph and then holds steady once above this speed Following this, a few weeks later (last weekend and again this weekend whilst on reasonably long blats - 50-100+miles) I've had 2 or 3 occasions where the box has jammed in 3rd at fairly high revs when I'm going for a change up to 4th. Engine seems to be fully disengaging with the clutch action, and once I've scrubbed off enough speed and the engine revs have dropped a bit and I've dipped dipped the clutch a few times again, I have be able to change gear both up and down as normal and proceed as normalI've managed to get under the car to a certain extent this evening (although only high enough through trolley jack and axle stands and I'm no slim Jim) and felt the speedo cable and angle drive which don't seem that tight into the gearbox (can certainly wiggle them around a bit), but whilst doing this noticed it seemed pretty oily around the gearbox and angel drive and cable. I was wondering whether it may be possible that the angle drive for the speedometer has managed to get dislodged and lose an oil seal or something and I have lost oil, and the gear jamming problem is resulting from resultant low oil levels in the gearbox. Planning to get it up on the ramps of a friendly garage so I can get it high in the air to have a proper look, but thought in advance I check on your collective knowledge gentlemen whether I'm may be on the right track or whether its more likely they aren't linked and something more sinister is causing the gear jamming. P.S. Thrust bearing on the clutch has always been a bit noisy/rattlely when foot off the clutch - I've never been that comfortable with it, although its done more than 12,000 miles like that and I've had no engagement or disengagement or indeed clutch slip problems and that's still the case Thanks for any thoughts in advance
