B4 Transmission problems - help

[Guest]

Hey,

I've been having a few problems with my transmission in my 99 B4, when it's cold it takes a couple of minutes to beable to change it into drive, reverse is fine.

When it does change it clunks into gear, also second gear does the same. I have topped up the transmission fluid before I get it changed next week and levels are still good.

Thoughts please? do you think changing the fluid will fix the problem? or could it be major?

Thanks,

Nicky

I changed the fluid in mine and found bits of metal in it. Changing it really did help the smoothness of the changing, but yours sounds like the gearbox is on the way out

Common fault. Way down deep inside the transmission, the low clutch seals are worn. The parts themselves are about $100, but there's a good 8 hours labour to replace them. In fact I did this exact job on Monday just gone. It's a good time to replace all exterior seals and gaskets to stop any fluid leaks too.

Thanks for your help

Hey,

I've just got a couple of quotes to repair the worn seals in the auto transmission, $1500 - do you guys think I would be better off buying a second hand transmission and can you recommend someone to fit it for me??

Cheers

1500 isnt 8 hours labour!, id say take it to boostin in auckland.

A secondhand box is an unknown quantity. At least you know whats wrong with yours. Just shop around for quotes. Just make sure they know what they're talking about. If they sound a bit vague, walk away.

I'd be suspecting a sticky valve given the symptoms.

If the clutchs are worn there is a lag going into gear but it is measured in seconds... not minutes. If it's taking minutes to engage gear then the clutches would be non-existant and there would be no drive!

Worn clutches don't "clunk" into gear.

I reckon there is some tiny speck of something(rust, metal, warpage due to loose bolts), causing a valve to stick in it's bore, then when the aluminium warms and expands after a few minutes the valve frees and moves to allow the fluid through to the clutch pack.

If it isn't a sticky valve it could be the OWC slipping.. then locking up with a "clunk".

Those would fit the symptoms... worn clutches dont.

As it has been said above its worn low clutch seals, common as.

Where did anyone say anything about worn clutches?

As boostin says, common as fault ! forward clutch seals worn out

Would have replaced atleast 50 sets of these in the last couple of years
