Hi All

I need a bit of advice please

I will try and explain this major palaver the best i can, so please bare with me.....

I have a 2004 Auto TD5 Disco.... About a month ago my Auto Gearbox started slipping and i lost reverse, so i went out and bought a 2004 Replacement gearbox for £600

I got in touch with my local garage who does all my service work to see if they would fit it, unfortunately it wasn't something they wanted to do....so they recommended another local garage who they send all there big jobs to.... i dropped the car off along with the new gearbox only to get a call 4 days later to say the box was no good and had no drive!!!

To cut a long story short.. it Turned out they had Knackered the gearbox oil pump and the flywheel when fitting it!!!

So i found a local Land Rover specialist, dropped the car off to them.. along with ANOTHER Auto Gearbox & Torque converter bought from a breakers with 30 days warranty

The local specialist said that the previous garage had bent and Knackered the flywheel when trying to fit the first box....So they charged me £100 for a second hand flywheel and fitted the second GearBox £400 in total

I went and picked it up yesterday...The first thing i noticed was a vibration on tickover that definitely wasn't there before!! it gets worse around 1200rpm then sort of clears but i can still tell it's there even though it's not vibrating the car to bits i just know its not right!

I Spoke to the mechanic who fitted the box about the vibration and he said "it's probably your crank"!!! (crank was fine before)

"or your second hand gearbox"

The new gearbox changes gear smoother than the original box!! its silky smooth... you can't even feel it changing gear.

When in neutral with no drive it vibrates....and when pulling away up to 12 1300rpm it vibrates very slightly

The Gearbox supplier is saying it's nothing to do with the gearbox....and its more than likely the second hand flywheel they have fitted..?

And the landrover garage is saying its 100% noting to do with the flywheel ......
(although they told me if i left the old one on the car would vibrate its balls off)

So im stuck in a bad situation.....the landrover garage are saying they will take the box back off...run it with a dummy bell housing and see if its the flywheel...If it is the flywheel they will change it at there cost and re-fit the gearbox....if its not.. ill have to pay them the labour to put it back together.

The Gearbox breakers are saying they won't change the box as its a tested working box...
" if it's changing gear fine and only vibrating on tickover and they have fitted a second hand flywheel its not the gearbox"

I've been on the phone all day to land rover and Auto Gearbox specialists, both saying it's more than likely the flywheel some saying it could be the Torque converter.....

So im stuck in the middle and gutted after all the trouble ive had to get my car back and Have this problem....

any suggestions or likely problems would be much appreciated

Thanks

I would be looking at the engine mounts. These are known to get tired and cause vibration transmittal . After all the pulling and pushing from the two gearbox changes I'm sure they are now ruined. Only get genuine replacements.

drive plate or its fitting,would be my guess ,dont people measure depth of t/c and protrusion of drive plate before fitting

You're about the 10th person that has said its the drive plate, but the garage are having non of it!!

There saying its the output drive bearing of the Box or Torque Converter out of balance....

Is there any chance it could be the Torque Converter out of balance?

If i get them to take it back out and its not the drive plate ive got to pay them the labour, which is fair enough as it wont be there fault, im just worried about using it incase i knacker something else

Sorry to say but you've dropped £1000 on what sounds like shoddy work, any reason you didnt have it done at Ashcrofts for £1250 supply and fit?

gap between t/c and drive plate is essential when box is pulled up to the engine(there are 2 reasons for knackering box pump 1 fitting t/c to engine then fitting box or there was no gap and so t/c is forced too far into pump which will damage pump and bend drive plate) , there are no support bearings in the auto box, there is a bush supporting t/c in pump housing but youd have a leak of box oil if that was an issue, if t/c works ok and locks up i doubt its that

Something worth checking, not directly related to the autobox. When Turners so called experts fitted my manual box in Jan, they bent the clutch plate etc. But they also damaged the CPS and the oil pressure wiring. A damaged CPS (crank position sensor) has been known to cause rough running.

If these people have already damaged the first autobox, theres a chance they knackered some wiring as well!
Have a look over the wiring ontop/around the back of the engine.

Thanks all ...

Obviously now i wish i would have just gone for a recon box, but cash was tight, so buying a £600 2004 box with 79k on it and spending £250 on fitting was my cheapest option....

I personally don't think its the T/C and the box changes gear fine... but im not a mechanic so i cant say....its going to an auto specialist on monday to have the box out again, its like driving on a cobble road !!

Hopefully not by the same people who are trying to "sort" your gearbox!
Call me a cynic, but its not in their interest to find a simple fault....no profit in that!
If you can, try to give it a quick check over visually using a torch first. Diagnostics dont always pick up intermittent faults.
Good luck!

Thanks.... Mark.... I'll get the torch charged!

Check that the harmonic damper on the transfer box is securely torqued down, if they come loose you can get some right vibrations.
