D3 Gearbox Woes?
Noticed when driving through Germany a slight vibration every now and again, dismissed it as just the road surface & thought nothing of it.
Heading on a long haul todaya when heavily laden (don't as Farmer Chalk ) it was back so paid a bit more attention. It happened when driving up hills on the Mway at 60, up a hill that was not steep enough to change down a gear. Vibration rather than a rumble or wobble. This happened a few times when my brain switched on and when it was happening I dropped a gear, it dissapeared. Ah ha me though, gearbox!!
On the 550 mile haul it was happening on steadily less steep gradient to the point that it happened once or twice going round a bend on the flat on the Mway, plus happened twice in 5th gear so had to drop down to 4th. Spending more and more time dropping down to 5th.
As per SWMBO's brainwave, checked the wheelnuts and all spotty dog on, things are never that simple.
Any thoughts oh learned sages out there?

Del, was this New Dee. Thought you had new TC so presume it was not the Judder. Is the rear propshaft donut still original? Could it be that or the middle bracket.2005, TDV6 S, Auto, 190k miles, owned from new, V8 Brake Upgrade, Nancom Evo, RLD protector, BAS EGR blanking & Remap, separate ATF cooler, changing all the fluids ahead of time.

Sorry, good point. Old Dee, D3, that had a new TC fitted Jan 16/20k miles ago. Different from the dreaded judder, much more of a higher pitch vibration. Trim was resonating with it.
New rear prop shaft couple of years ago and nothing noted in MOT couple of weeks ago. As propshaft speed wouldn't change with gear change, how would the vibration dissapear on gear change? Question asked as non techie.

Whilst driving when you get the vibration, knock the gearbox into neutral and see if the vibration goes away.
Don't worry nothing will happen to the gearbox while coasting in neutral as long as engine is running.
You can put back into drive whilst rolling as well.
This may give an indication if it is the gearbox.

Like when shifting down a gear, the vibration dissapears immediately when sticking it into N as soon as the vibration starts.
Spoke to chap at a well recommended autobox specialist and he thinks it TC related again. I accept it's difficult to diagnose over the phone. Well out of the Bristol Transmission's 12 month/12k warranty, I'm in two minds whether to phone them, I know it'll be a case of "bring it in and we'll take a look at it", plus if their TC has only lasted 20k not sure I'd want another in there.

Agreed, not like as before when original TC was on the way out. No rumble through 20 - 30mph band, just high torque/high gear situations like going up a hill in 6th. And vibration rather than rumble.

When you had the TC done did you also get the stator bush done?
Could it be under a certain load the worn bush is vibrating?05 V8 HSE Bonatti Grey

Couple of bits of the puzzle that I haven't mentioned. No fault codes on the car and the gearbox was filled with proper ZF fluid when BT fitted the new TC. Doesn't get us any further but bits of the puzzle are bits of the puzzle.
I am kind of assuming it is autobox related, not something in the engine that doesn't like load at low engine speed that goes when it spins up on a gear change.

I think i get something like this. Generally only on motorways, perhaps when going slightly uphill that is not steep enough to change down. If i change down to fifth, it disappears. If i take my foot off the "gas" pedal it disappears. Considered it to be EPB related, or perhaps worn CV joint somewhere ??
