Fifth gear keeps jumping out.......

Mark II Golf GTi 8v standard.

Hi all,

She's sick again........

Recently, my Golf has been jumping out of fifth gear on the motorway. This usually occurs after I have covered about 70 miles plus, then it tends to do it every 2 to 4 miles.

This does not happen under harsh acceleration - I have tested it this way and brutal pumping of the gas on the motorway is fine.

The car has covered over 180K. Four questions:

1. Would a transmission oil change help?

2. I am thinking of redoing the linkages, as shown by Rubjonny, what are the GSF, or VAG numbers, I think GSF have stopped this?

3. Where can I buy the gear alignment tool, I cannot find it on Ebay anymore?

4. Is this a more serious problem than linkages and oil?

Thanks again.

Sounds like the box is low on oil, and that 5th gear end is overheating and playing up. It might already be mullered, but change the oil anyway first, it'll only cost a tenner.
Bet you'll only get a cup full of oil out of the thing!

 

Thanks

Dear Hotgolf,

I did as you said and you were right!

I grabbed a beancurd tray and an empty large can of Jolly Green Giant sweetcorn. Just about filled the sweetcorn can and the oil was a horrible murky muddy brown.

Two litres of Grandville hypoid 80-90 later, I was tooling it down to Brighton and it worked sweetly. Mind you, it was -1 degrees and snowing, so who knows? I am going again tonight and will hope for the best.

Many thanks.

I have a 5th gear set lying around if it is mullered!

 

mine did this and then about a month later it just exploded 5th as if you had the clutch on in 5th lol

i advise getting the number off the guy with 5th gear for sale! lol

 

jesus... sounds like it was on the original oil. thats just asking for trouble

 

Thanks............

Dear Matt,

Thanks, if you could get in touch with me via my private message, that would be much appreciated.

Thanks...

Dear Matt,

Yes, you could well be right.

The guy I bought it off specialised in VW Golfs, raced them and seemed to know his stuff. When I asked him any other stuff I should keep in mind, he advised regular gearbox oild changes.

Whether or not he did it to that actual VW, I question.

hmmm @ regular changes. maybe because it was leaking it?

i did mine when i got the car at 144k and there was plenty in there but it was black as a black thing. i changed that again after another 60k miles and it came out clear

worst case youll need a replacement gearbox. second hand, the one i bought once cost about 100

 

VW don't specify a service interval for the gearbox oil - just keep it topped up. Changing it won't hurt though.

 

Thanks..

Dear Matt,

Thanks again. No, the bottom of the gearbox has always been dry and when it has been MOT'd in the past, the mechanics have always commented on how dry it was for a Mark II Gti.

It was more the point I was a prize *rick and did not check it, like I do everything else.

Have covered 700 miles since and it has been sweet and returned slightly better fuel economy.

Thanks...

Dear aminder,

Thank you for chipping in and suggesting this oil.

Would you be so kind as to tell me where I can buy this?

Hi rubjonny,

Thank you for your thoughts on the MT90 oil.

Is what I put in,(Grandville Hypoid) appropriate for the my 1989 Mark II 8V Gti?

Secondly, I am going to do the linkages on my Golf soon, but cannot find the alignment tool! The link you sent me for Ebay does not seem to work, either. Can you help?

Thanks for the link . Thanks Club Gti for pulling me out of the *hit again.
