Shagged syncro. Gearboxes often get raped changing from first into second at high revs and the syncros get hammered. |

Rather than start a new thread, decided an almighty resurrection was in order Essentially I'm having a similar problem, though not letting it hit the limiter by any stretch of the imagination! I recently changed the gearbox oil (75w80) Halfords own brand - will this stuff be utter cack? Would it be recommended that I get some stuff from a dealer? If it turns out to the spring clip on the sychro hub - how would I go about fixing this? A search didn't appear to throw up any answers... Cheers in advance guys  ________________________________________ Blaze 6Keep It Standard |

Worn gear linkages can cause notchy gear changes/selection. Even new ones don't last long. I changed gear linkages 3 years ago (30,000 miles) and they were worn. The new linkages transformed gear changes/selection again and removed any trace of notchyness. Lubricating the control return arm and rubber ball and the selection bar also helps. |

Ok, cheers guys - thanks for the replies. It seems like it could be a number of things, but I'll probably start with the gear linkages. Then it'll be clutch or looking at the synchro hub spring, though still not exactly clear what this is!I'll try to remember to update this thread if and when I get the problem resolved. ________________________________________ Blaze 6Keep It Standard |

to do the syncro hub spring will be a gearbox off and strip job, to do the clucth and then the gearbox build at a later date will be very labour intensive, best just get the box done and fit a new clutch at the same time |

You can change the clip leaving the box in place, I;ve done a couple like this before but not the easiest of things to do.________________________________________ 306 Rallye Sptint/Race Car, 205 CTI 1.9 8v to name a fewRoad, Track and Race/Rally car preparation to your personal requirements, Full Workshop & Diagnostic Facilities New and Second parts, from Plugs to Turbo's We now also carry out Routine Servicing www.pugracing.com & FB Page, https://www.facebook.com/PugRacing Ebay; http://stores.ebay.co.uk/Pug-Racing-Shop 2012/2013/2014/2019 Class Winners at Gurston Down Speed Hillclimb & Joint overall, Class record too along the way, |

Right, changed the gear linkages today with Miles'/PugRacing ones. Getting those clips in was a bit of bugger though - my patience was wearing thin by the end!While the overall feel of the changes is better, feeling more direct (less 'give' in the throw), I still have the same crunching when making a quick 1st to 2nd change... So it look like I'll need to get the gearbox off and change the clutch. I've never done this before, nor have I done any of the jobs that I've done over the last few months before, but have gained some confidence. Though changing the clutch should be relatively straight-forward (if a little labour intensive) from what I've read and from what I understand, the syncro hub spring - what's the deal with this? Will this involve opening up the gearbox itself? Any advice is welcome. Cheers Rob ________________________________________ Blaze 6Keep It Standard |

I'm also getting a wee bit of crunching on shift. I've got a stiff clutch, but not as bad as some, so I think it may be this linkage issue? I'm not technically minded in any sense of the imagination. So if I asked my garage to change he gear linkages they'd know exactly what I meant and needed?________________________________________ CLUB BLACK RALLYE||B8s||60-70mm drop||Black Partner Steels||P1 VTS Rack||Refurbed Beam||Hybrid ARB||VTS Torsion Bar|| |

I'm not technically minded in any sense of the imagination. So if I asked my garage to change he gear linkages they'd know exactly what I meant and needed? Absolutely. Though I changed the gear linkages myself, I still consider myself to be a bit of a novice. The 'Idoit's Guide' may go something like this: the gear linkages are what connect the gear stick to the gearbox. There are 3 of them, 2 short ones and one long one. They connect to the gearbox's selector forks (my term - not sure if this is the official term mind you) by way of rubber bushes that are integrated into the gear links themselves. These bushes, like any rubber bushes, degrade over time, meaning one will have more 'play' or slack when attempting to change gear. New ones will eliminate this and make gear changes fell more direct, i.e. less like stirring custard! Reading someones's guide to changing the gear linkages here suggested that the hardest part was to remove the old ones adding a top tip which was to use a suitable-sized spanner to prise them off the metal balls on the selector forks. This was then quite easy. Fitting the new ones was slightly fiddly since I bought the bushless upgraded items (from Miles on here). I would suggest taking the battery tray out as this gives you loads of room to work in. I still intend to change the clutch as the gear linkages themselves haven't eradicated my problem... Let us know how you get on. Cheers Rob ________________________________________ Blaze 6Keep It Standard |

Got a similair issue with selecting gears but onl yafter a bit of a run when the oil has had a chance to heat up.T'is very notchy going through the gears and grinds going into reverse. Oil has recently been changed for pug stuff and has Miles linkages. Can get all gears + reverse no problem when the car is cold. Any sugestions?? Thinking of changing the clutch cable first.

My gears are good apart fro a hard downshift(track day) into 3rd gear, I asume this to be the 3rd gear sincro mesh. Is this correct?Edit : Its a lot better if i blip the throttle first If your a novice i would not recommend opening up a gearbox , just buy a second hand low mileage one. ________________________________________ Phase 2 Blaze GTi6PS3 - Black Ops 2 Engine crane for hire Renfrewshire |
