smithysmoo Posted November 29, 2012 Report Share Posted November 29, 2012 Have searched already but couldn't find anything and new to these Lupos...1.4 Tdi goes up fine through all the gears but when downshifting struggles to go into 3rd, can find it eventually. Every other gear ok and no untoward noises. Gets in to third fine when not driving.Any ideas for me to look at??? Cheers Quote Link to comment Share on other sites More sharing options...
Defcon5 Posted November 29, 2012 Report Share Posted November 29, 2012 Does it go straight in if you rev match? Quote Link to comment Share on other sites More sharing options...

smithysmoo Posted November 29, 2012 Author Report Share Posted November 29, 2012 Not sure never tried that I will give it a whirl and let you know what the outcome is. Quote Link to comment Share on other sites More sharing options...
Cooper_GTI Posted November 29, 2012 Report Share Posted November 29, 2012 Could be a whole manor of things;- Clutch- Shift cable adjustment- Synchromesh- You're not pushing hard enough- Driving styleTry double 'D' clutching for a smoother downshift. Or even just a quick blip of the throttle on the downshift will help to match engine speed with gearbox speed.If you're unfamiliar with this, here's a quick rundown;You're in 4th gear at 2000rpm and theres a sweeping corner coming up.You brake gradually and the revs drop to 1500rpm and feel the need to shift down to 3rd.Push the clutch in and as you move the gearstick forward (through netutral and into 3rd) blip the accelerator slightly, to roughly where you think the engine revs will be when you're actually in third. (probably around 2000rpm again).The way i normally do is to rev past the point (i.e. 2500rpm), as by the time you've slipped in from 4th to 3rd, the revs have normally dropped to where youwant them to be.It's a good way to drive and i do this every time i downshift, no matter what car i'm in. Takes a bit of practise, but once you've got it sussed it makes for a brilliantly smooth drive, as well as less wear on the gearbox, clutch and driveshafts. Then you can incorporate heel and toe braking, although this isn't necessary for the road. Quote Link to comment Share on other sites More sharing options...
scotty_82 Posted November 29, 2012 Report Share Posted November 29, 2012 (edited) Blipping the throttle on every down change does mean more petrol getting used though, kind of a trade off.Cooper i think youre jumping the gun a touch too, defcon was asking him to do that action a few times to help diagnose where the problem may lie, if it goes in without a problem whilst doing it there is probably i think a syncromesh issue.

smithysmoo Posted November 29, 2012 Author Report Share Posted November 29, 2012 (edited) Well when I take it out I'll have a look.I'm definately pushing hard enough,...Had alot of cars Mk1 and Mk2 golf Gtis a G40, polo 1.9tdi, T4's, caddy's so never really had a problem before so would rule out driving style and pushing hard enough.I notice from the receipts it had a new cable not so long ago so am wandering if it may be needs readjusting, but as I say goes up the gears fine, and only into 3rd thats a problem.Was thinking bout changing the gearbox oil as doubt thats ever been done and its getting on for 140k.

smithysmoo Posted November 29, 2012 Author Report Share Posted November 29, 2012 (edited) Just been and tried it hit the throttle when clutch is dropped and still don't go in. Any more ideas....

Cooper_GTI Posted November 29, 2012 Report Share Posted November 29, 2012 Synchromesh i'd guess at.Throw another box in it.Lack of gear oil shouldn't really affect the engaging of the gears i wouldn't have thought, it's just there to lube/cool the bearings.

smithysmoo Posted November 29, 2012 Author Report Share Posted November 29, 2012 I thought doing the rev match thing above would suggest then that it wasn't a syncromesh issue??Cooper, was trying to go down the easier options than throwing another box in at this point.

Cooper_GTI Posted November 29, 2012 Report Share Posted November 29, 2012 Matching the revs will just help it slip in and i thought you could maybe use it as a permanent fix to be honest. You can actually change gear without a synchromesh at all using the above method and dumping the clutch between shifts.Although a dodgy sychro normally shows itself by crunching gears.

scotty_82 Posted November 29, 2012 Report Share Posted November 29, 2012 Rev matching is not a fix, something is still broken or worn which that will eventually need sorting. Quote Link to comment Share on other sites More sharing options...
Koop Posted November 29, 2012 Report Share Posted November 29, 2012 I thought doing the rev match thing above would suggest then that it wasn't a syncromesh issue??That's how I interpreted it too. Could need the linkage adjusting if it's just doing it on one gear. Quote Link to comment Share on other sites More sharing options...
Cooper_GTI Posted November 29, 2012 Report Share Posted November 29, 2012 I doubt it's a case of adjustment to be honest. If it were, you'd be struggling with 1st, 3rd and 5th, as there is only one rod that moves the selector forwards/backwards.Time for a new box imo. No biggy really, they're fairly cheap, easy to change and it's a god time to stick a new clutch in it too. Quote Link to comment Share on other sites More sharing options...
scotty_82 Posted November 29, 2012 Report Share Posted November 29, 2012 Yep i think Coopers diagnosis is probably right, maybe a new box time. Quote Link to comment Share on other sites More sharing options...

smithysmoo Posted November 29, 2012 Author Report Share Posted November 29, 2012 Seems strange every other gear is absolutely sweet as a nut and slick... and third is fine going up, actually found it coming down a little more on last drive out. Is it possible it could be clutch cable or would this mean that all gears were dodgy.If I need a box any suggestions for places to go to get one?? Don't help theres no haynes manual for this model.

IlsonDanni Posted November 29, 2012 Report Share Posted November 29, 2012 Before you go mad, try changing your Box oil; mine used to put up a bit of a fight at times, put fresh oil in and it's running fine now. 1 Quote Link to comment Share on other sites More sharing options...
smithysmoo Posted November 30, 2012 Author Report Share Posted November 30, 2012 Did you use the vw stuff or get some from somewhere else. Quote Link to comment Share on other sites More sharing options...
Cooper_GTI Posted November 30, 2012 Report Share Posted November 30, 2012 Did you use the vw stuff or get some from somewhere else.Doesn't have to be VW.Be cheaper to get it from a motorfactors. Can't remember what oil it takes, think it's EP80/90. Make sure you use the right one! Quote Link to comment Share on other sites More sharing options...
Defcon5 Posted November 30, 2012 Report Share Posted November 30, 2012 (edited) I believe most Lupos use 75w90You may as well try some Forte gearbox additive in there too Edited November 30, 2012 by Defcon5 Quote Link to comment Share on other sites More sharing options...
smithysmoo Posted November 30, 2012 Author Report Share Posted November 30, 2012 Is it likely the clutch cable might just need adjusting or would I be finding all gears hard if this was the problem. Quote Link to comment Share on other sites More sharing options...
