thobo 0 Posted May 3, 2011 Report Share Posted May 3, 2011 When I rag it through first it properly crunches into second, fine when I drive normally but horrible when I dont.I'm guessing its the gear linkages, how would I go about fixing this? I know on my old rover it was a "fairly" simple job, still took me ages though! Link to post Share on other sites
spindat45 0 Posted May 3, 2011 Report Share Posted May 3, 2011 Hi.It's very unlikey to be gear linkages as it would crunch or be hard to select gear regardless of what speed.. Sounds more like the synchromesh in the gearbox on second gear. Basically the synchromesh speeds the next gear up to the same speed as the main shaft (layshaft) so you can engage second gear smoothly and without crunching. I had this problem with mine in the original box and it was confirmed when I had it reconditioned. I've had a few boxes reconn'd for people and I always ask my gearbox specialist to pay attention to second as it's a common thing due to the fact that second gear does tend to take a hammering. I would hazard a guess that if you rag it but take your time with the gear change, it doesn't crunch? That would be because the engine speed has time to drop closer to idle.It's a long shot but replacing the gearbox oil "might" help but I very much doubt it. Worth a try though.Kevin Link to post Share on other sites

Worth a try though.Kevin[/quote']that sounds spot on, it could have come into problem as the gearbox looks a lot cleaner than the engine so I'm assume its been changed fairly recently. Is it bad for the box to carry on with it?What would be a cost effective fix? Or is there not one? Link to post Share on other sites
spindat45 0 Posted May 5, 2011 Report Share Posted May 5, 2011 It's only bad if it crunches as noise = wear but over time it could get to the stage where it crunches regardless of speed. I drove mine for well over 2 years but I'm a "conservative driver" most of the time. It did mean holding back a bit on the first to second gear change but it didn't go altogether or get any worse.The cheapest option would be to have it repaired/reconditioned. That way you would know that the entire gearbox was ok. Alternatively buy a secondhand gearbox but that comes with obvious risks. I bought a secondhand box and had that reconditioned. I kept the original as a spare once that had been sorted.If you go down the recon' route or need to replace the gearbox oil, I'd strongly recommend using a gearbox oil called Redline MT90.Kevin Link to post Share on other sites
Lukey. 381 Posted May 5, 2011 Report Share Posted May 5, 2011 i had this issue and replaced the gearbox oil with redline MTL and its not happened since and the shift is much better in general Link to post Share on other sites
