Clutch and gear box trouble


Recommended Posts

I have a 13 year old td5 defender 110. Recently the gear stick is grinding and struggling to get into gear.I've bled new clutch fluid through the clutch master cylinder and replaced the piston cylinder at the bleed, but it's getting harder to ingage the gears.I'm a bit worried about driving as I don't want to do more damage. And am worried that I'm at the mercy of a massive mechanics bill. Has anyone any ideas as information is king. Thanks for your time and advice. Cheers

Hello and welcome to the forum, You could try new gearbox oil? is it all gears you're having trouble will, How is selecting them when the engine is off?... try distinguish if it's a clutch issue ore a gearbox issue... what millage you running too?

It's good practice to replace both the master and slave cylinder when working on clutch hydraulics . Doing this will cover all the cheap fixes , if the dragging clutch is still there after doing this then I'm afraid you will need to consider clutch (and possibly DMF) failure . It's not a guaranteed thing that the DMF will have failed but it's worth being aware ..

welcome to the forum as well

cheers

I had similar problems but with individual gears. Decided to bite the bullet and was either a recon box or get original stripped and rebuilt with new parts for defective.

In the end went for a rebuild worked out slightly cheaper but not much as i had all original parts fitted (dont bother with aftermarket wont last).

As for the cost you dont really want to know ouch.

Runs great now like a new box worth the money, depends how long you plan to keep your pride and joy. As for me I wont be buying another so have it till I turn my toes up so worth it.

Couple of other comments I tried canging the oil but without success, changed both master and slave too without sucess. I supplied specified oil when box was reconditioned as I had some left from previous oil change and the second gear was still a pig until the oil warmed up. Took it back to transmssion specialist he said he uses an automatic transmission fluid usually and swapped it over. Never had a gear change problem afterwrds, the other bonus was all gaskets and seals where replaced at same time so no more nast oil leaks, which pleased my wife as my drive was looking a mess before hand.

Having an absolute feckin nightmare. I got the gears back up and running. Changed the clutch plate,fly wheel and installed full clutch kit. 700euro lighter but everything was running smoothly. The mechanic who did the work is a friend and has a good history with defenders and 4x4s.I drove it for 4days and after doing 300km or so started to get a weird dragging and grinding sound as if something was loose in the gearbox and dragging on the road.the noise is there through 1st 2nd and3 rd gear after that it disappears.my mate is on the other side of the country so he asked me to take it to mechanic.. Ended up in land rover garage..they have given me a diagnostic of complete transmission and gearbox failure. News is I can spend 10 k on new gearbox and transmission or rebuild for 3k but my friend the mechanic says very unusual for the two to go at the same time. Td5 160 on the clock. It seems ludicrous to everyone I have spoken to. Any advice? Frustrated!!

+1 for Ashcroft transmissions, we've used them for diy swap on transfer box then a drive in swap on the auto mainbox. (their drive in service price included a hire car and fluids). Which was a nice day out at bletchley park. Not sure if there is a garage close to you who could do the work (noticed you'd quoted euros)

If you put it in transfer box neutral when stationary does it still make any noise thru the gears ?

Is there any noise in reverse ?

I would tend to agree with your mechanic in that complete trans failure is highly unlikely .

Maybe drain the main gearbox oil and see what comes out ?

cheers
