great - after nearly 3 months my 350i is back on the road with newly rebuilt gearbox. 1st, 2nd, 3rd, 4th are lovely....smooth and quiet and lovely. But put her in 5th at 60mph and the car vibrates and rumbles. Terrific. Any ideas anyone? (other than buying an Escort/Mondeo/Panda...)

You say gearbox is newly referbed? First thing I'd do is take it back to whoever refurbed it and get them to repair it (and get it out the car).
No ideas what it is / could be though I'm afraid...

yep that's what I think - but of course the gearbox repair shop doesn't remove/refit so I imagine getting them to pay the dealer to do that will be like getting blood out of a stone....

In that case, you give them the car, for a reasonable amount of time (maybe a few days?) and advise them that it is their problem - not yours.

Do you have anything on your receipt reagarding warrenty etc?

Would be great if they look into it but it's doubtful. Their liability will be limited to the gearbox and it's repair, not with the rest of the vehicle or box removal. Unless of course, they initially removed and refitted the box.

In that case, can they find you a garage (maybe they know a local garage owner) who will remove and refit for "mates rates"???

My garage charged £175 to change the box and the clutch including Vat! - The gearbox refurb and AP clutch kit on the other hand cost considerably more.....

Time to find out where, methinks...

Near Cardiff I think!

Sorry to hear your woes Sprev. Have you rang them yet? Seems strange it's only in 5th

thanks dickymint - no not rung yet as I want to rule out any other cause. As you say, odd that just in 5th and only realllllly noticable at about 50-60mph. When it does it, if you drop to 4th the vibration goes so it can't be propshaft or wheels. I'm just checking that it isn't a misfire under certain load conditions as it does seem to run rough at low revs at the mo, but failing that it must be in the box. I think 5th runs on a separate layshaft so it could be a faulty layshaft or bearing methinks...

Could be loose prop - check the bolts. Disappears in 4th because the torque output changes. I've seen the same on mine. Fingers crossed.

If the bolts are good and tight, undo the gearbox end and put it back on 180 degrees turned around, it might be better one way than t'other.

thanks adam - the dealer already turned it 180 so the bolts should be good an tight but I will check - you never know...

Put it this way - I had mine in the same place many years ago and they failed to tighen up the driveshaft nuts after replacing same! Luckily I spotted it pretty quickly and torqued them up.
