Got a 99 mini facelift elite 2.5 V6 automatic, and it has give up the ghost.

When I engage the gears(doesn't matter which), it doesn't go anywhere....well it does but you haver to rev the tits off the car to move 1 yard.

Any idea what could be wrong?

Check the fluid level first, if ok then try changing the box filter and fluid, then if no better a 2nd hand ar30 will do the trick, and before you fit that change the trust washer to make sure everything is tip top and dandy.

[PaulyQ]

cheers mate. Seems a bit more severe than filter/fluid but could be wrong so will check it out.

2nd hand AR30's .... are they the standard box or better?

[ffcgary1]

AR30 WAS THE BOX FITTED TO THE 3.0, AND THEREFORE ABLE TO TAKE MORE POWER AND THE AR25 WHICH YOUR CAR HAS GOT IS A BIT WEAK.

[PaulyQ]

just need to find somebody to fit one or to play about with mine, autobox specialists are extremely thin on the ground up here.

[Marks DTM Calib]

Its an AR35.....there is no AR30.

The fault sounds like a lack of fluid or a lack of pressure which is affecting the torque converter operation.

[ffcgary1]

Sorry my mistake, your quite correct mark as usual,  Whata mistaka to maka.

[PaulyQ]

Had car in for a major service last week and have just been on the phone to the geeza and he reports that there was no leaking at all from gearbox and he didn't know how to top up gearbox levels, which is fair comment since he never works on them. To be fair I don't think the box will have ever been topped up since new apart from one of the vauxhall services at maybe 40,000 miles.

Anyways, will report back

[PaulyQ]

How would I change filter box and does it need special tools?

Asking as my mechanic hasn't got a clue how to do it.

found out how to check the autobox level via the guides but have a question... where is the oil level plug? When it comes to auto's both me and the mechanic are complete noobs.

cheers

Did it just happen or has it shown signs of failure, i.e. losing drive when going round a roundabout, up a hill etc... trying to define if it's a fluid level issue or not...

[TheBoy]

If you've really let the autobox slip, its will be knackered.  If it has only just happened, and you haven't let it slip too much, you may get away with a fluid change

[Dave-C]

Fingers and toes crossed for you, however there's an AR35 in Shropshire....  I've tested it on a scrapper prior to it being stripped..

1st thing... went around roundabout and it went. Was getting a tad lumpy on changes as well, so am definately erring on the side of caution and thinking it's the levels.

@theBoy: It did around 10 maybe 20 yards or so with it slipping. Had to do that so I wasn't on roundabout....think that will have killed it?? It still "clunks" when I put it into gear, just doesn't go anywhere.

After reading a bit I understand it's best to top up the oil when the oil is warm.... hows that going to happen if I can't take the car for a drive to warm it up?? Would it be best to top up the oil as best as possible.... take it for a drive(assuming the gearbox isn't a goner) and then re-top up?

As for filter box etc.... any links on removal/replacing?

Cheers chaps.

Thanks Dave C for the link.... will give him a phone if new box needed.

No expert me .. but if it was mine I'd drop both sumps and throw away any remaining fluid as well as changing the filter, then replenish the fluid, run it for 500 miles - if it works ok - and then change the fluid again. Damned sight cheaper than replacing the box IMHO  

Level check how to :

Thanks Entwood.

Location of sumps? Tools needed? No expert myself and need to try and explain this to the guy that is going to be doing the car.

Just hoping that the box is not dead.
