hi all,

can someone please tell me if the autobox which appears to be staying in the lower gears, rev high and then go in gear with "automatic gearbox" on mfd, would this indicate ie, low transmission fluid or maybe worse the box being knackered?

any help with this would be greatly appreciated

Checking or changing the transmission fluid would be the first call, see the Maintenance Guide for more info for this.

Isn't the order of play to top up (or change) fluid, clean the selector switch.... then replacement if none of that works??? For us non-gearbox specialists that is?

(Ps, I'm not suggesting you do that.... just wondering out loud if there's much more that can be done with a naughty gearbox

Here goes yet another auto box playing up. I swear they are made of cheese.

Don't bother changing the fluid. Just check the level and read the trouble codes.

Could also pop the front sump to check for remains of thrust washer..

The auto box ar35  packed up on my irmscher 3.2 elite whithin 10 minutes of buying it of a guy on eBay, 
It kept losing drive and then  would be ok for a few miles,  I tried the selector switch and fluid and
filter change, both sumps spotless,   and it still played up. Cheapest option was a second hand box,
Now all sorted,

That's hardly fair James. If serviced they do go on to do serious miles. I think the main issue is Vauxhauls stance, refering to the box as a sealed unit, when it clearly isn't and needs the fluid changing every 60/80k.

Most shift quality issues with these are fluid level/quality or solenoid related on the v engines and also include cam sensor issues on the 4 pots. Sadly if these aspects don't help they are not economical to repair.

I hate to agree with Gixer, but they are pretty robust if maintained properly. Actually, they are pretty robust even if they are not

Of all the Omegas I've had, and all the miles I've done in them, I've suffered the usual AR25 in a chipped TD problem and a huge oil leak on my beloved MV6 when a (relatively new, pattern) sump gasket failed. The latter also highlighted bits of thrust washer.

My MV6 is now well over 200k, has had a hard life since I got it at 88k, and had its first ATF change at 150+k, so you can imagine the state of what came out  . Its had another ATF change since, due to the leak it developed, and that was obviously a nice, deep red.

Reminds me, come the summer, I ought to do the 82k TBE
