SELECTION PROB HELP!!!!!!!!!

[m.a.t.t]

i've got a 1.2i 5 speed 92 reg im having problems selecting 5th when car gets warm, i have no problems when car is cold, please HELP!!!!!

[mowgli]

OK you've got me, All I can assume is that something in the gear linkage needs swapping, or the exhaust is very close to something in the linkage, causing it to warm up & melt

Give us some more info to go on.........

[Chris LR]

SR always did that.

It will go in with enough force! (Well mine did)

[mowgli]

I've had a brilliant idea , just keep putting ice round the gearbox.....

Keeps it cool

Sorry, but the nurse only lets me have one brilliant idea per day!!!!

[mikeoxford]

hmmm follow the haynes guide to adjust / setup the linkages correctly.

i did that on my old nova and it worked wonders.

on my old car it seemed fifth was diagonal right if that makes sense.

i couldnt get it in gear if i went right then up :?

I had this problem a while back, like you it was only when warm and even then not always. When changing from 4th to 5th I just couldn't find 5th at all. You could get round it by going into 3rd then directly into 5th but I got fed up with that and changed the gearbox oil (the proper Vauxhall red stuff - Dexron III - I think) this did the trick and I never had a problem after that.

where do you do the gearbox oil???

[Evolution]

Im not 100% sure about doing a complete oil change on the transmission as i dunno how to drain the old stuff, and the haynes manual seems to be a little sketchy on details, but in chapter 6 it tells you about maintenance and tells you where to top up the oil.....if that helps.

[Aragorn]

yank off the bottom cover plate and it shoudl all pish out

[Dicko]

only way to get it all out is to take bottom cover plate off., which is about 9*11mm bolts.

[Manta Mad]

Yes thats right, only way is to remove the bottom plate - just unbolts and the oil drains out into whatever you have ready to catch it! Best to use a new gasket although I didn't and there were no leaks afterwards - just give the mating faces a good clean.

For some reason you must refill the oil through the breather hole on top of the gearbox - the breather vent unscrews with a spanner. Check the level by unscrewing the oil level plug - front passenger side, top right hand side of where the driveshaft comes out of the gearbox - if oil flows out, level is OK. Capacity is in region of 1.6 - 1.8 litres.

ok i've changed the gear box oil,adjusted the linkage, but im still having probs selecting 5th when warm.Im having to depress my clutch twice to get into 5th, anyone have clues?

[Manta Mad]

What type of oil did you use - normal brown gear oil or the red Dexron stuff?

[mikeoxford]

why is this so under publicised because surely transmission oil is as imprortant as engine oil............?

i think ill be checking mine JIC

[whitey]

ha, i get that but not when moving!

Just when tryin to go into reverse, can take three attempts! Also It really crunches into 3rd sometimes (like im a learner driver), I always have foot rite down on clutch but it still does it now and again!

Any ideas?

do u ease of the acclerator a bit?

[Manta Mad]

I think the Haynes manual mentions the oil types or rather 'special oil' - whatever that is but its a bit vague (strange for Haynes :wink: ) I only found out when I tried to top up mine with normal gear oil and out came red stuff - did a bit of research and found out what it was. I have had BMWs in the past, earlier ones had the gearbox fitted with normal gear oil and this had to be changed every 20000 miles - they often had a notchy gearchange. Later models had Dexron (red oil same as auto boxes) and the change was much better - guess Vauxhall came to the same conclusion.

[m.a.t.t]

I don't believe that its my gearbox oil , could it be that my box is knackered or my clutch ?If its my gearbox whats the the best 1 2 replace it?

[Manta Mad]

You could be right but really what I was saying was, what type of oil did you put in - if you have put normal gear oil in, it would be worth trying Dexron to see if it makes a difference (it worked for me) - certainly a lot cheaper and far less hassle than replacement gearbox or clutch although if the oil change doesn't work, I guess these things are next on the list.
