Thread: T/C leak,has anyone got a guaranteed fix.

Is it leaking gearbox fluid or transfer case fluid?

Either way, are you replacing the the sleeve that both seals run on?
Its cheap and not difficult to replace.

Daz,the Tdi has been leaking for 15 years and the TDCi started about a month ago,I have a feeling both are leaking from the intermediate shaft or T/C input seal.I don't want to remove the T/C's because they are an awkward PITA on your own in the driveway so I'm thinking of sliding them back on longer bolts and a trolley jack enough to either get a good bead of sealant in between or a gasket.The best fix is a sleeved casing but that's not going to happen at the moment.

I'm also interested in this issue. I got the T/C re-sealed and a 'new' reconditioned R380 fitted 18 months ago. Already something is leaking. On my list today is to find out which one.
Then comes the job of pulling stuff out and fixing it, so I don't want to do it again for a long time.

Awkward you say??? .....and.... its a Defender.
Your talking about the standard transfer case leak, good grief dont bodge it up with goo, sheesh..
The old Defender is prolly due for a rebuild by now anyway?
And the "new" Defender has done what 100 - 150K? so hrmm same same

For goodness sake, just pay me the big dollars and send both to me to fix

From what I've read and experienced the leaks is usually the intermediate shaft O rings.
There is a modification where the housing is machined and a sleave inserted the stop the leak.
Ashcroft Transmissions
There are members on here who have done this modification locally too.

Rebuild Pffff,she's only done 507K,just bedded in.All the improvements such as sleeved housings etc only work for a year or two before they start again,the reason I'm thinking of sealing the two halves together.A few hours work with a good flexible joint sealer is worth the effort if successful.And yes the T/C is awkward for one person lying on their back in their driveway,we don't all have a hoist in the back shed .

No no no... that wont work! because the intermediate shaft is just about clear of the gearbox adapter housing so sealing between the two wont work.
And if you mean sealing between the two as in from left to right, in between the two housings...... then well thats just a disgusting thing to do to a Defender..... and it still wont fix the leak


If you persist in complaining about ur leaking Land Rovers, do this...
Remove transfer case.
*undo retaining nut on intermediate shaft and tap back a wee way and remove o-ring.
*clean end of shaft and as much of the transfer case face around the shaft as you can with brake clean and a brush.
*replace oring, and then use your sealant (I use Dow Corning 732 white on transfer cases) apply sealant around shaft (yes round the o-ring, all very incorrect).
*refit, apply sealant over the end of the shaft, you will see that the shaft once fitted back will sit a few mm below the case face, fill this with sealant and use a flat tool/scraper as like a putty knife and trowel it flat.

If you have been squeaky clean this will work.

I've done the O rings and seals in both vehicles,as have many owners,what your saying is similar to what I was looking at doing.It's just annoying that the intermediate shaft is covered by the gearbox housing,another half inch more clearance you could do the o ring without removing the T/C.
