Autobox headache

Something bad had to happen sooner or later I suppose 
My autobox has just suddenly started refusing to select 2nd gear  ....Pulling off from stop in 'D', the box just stays in 1st, ease off the accelerator & it drops into 3rd....or pushing down on the accelerator when in 3rd & it drops straight into 1st  .....Put the box in ice mode & it seems to pull off fine in 2nd
The ATF is at the correct level, smells good & is an acceptable reddy/light brown colour with no bits on the dipstick. I've not checked the MAF yet (bit late), so could possibly be a cause  ....Also, could a faulty TRS cause this problem ?
Any advice or clues as to what's going wrong would be hugely appreciated 
Please, please, please don't let it be terminal

JC.
St George's day was last week Is there a possibility that your shift problem could be a faulty shift switch,that big expensive looking thing on the left side of the transmission,they have been known to suffer from bad contacts.Talking as we all do about the MAF,on my return home from the FMD the other day,the transmission went into neutral by itself,the engine roared,I moved the stick down and it slammed into second,creeping home I was sure it was the end of the road for the box but yes you have guessed it,I cleaned the MAF and it resumed it's silky smoothness.Hope the foregoing gives you a little hope.
GOZZ.

Right then, tried cleaning the MAF & even replaced it with a spare, but no difference
I may have mis-diagnosed the symptoms though ....Although at first it appeared that 2nd gear was not engaging, I'm now not certain it is actually a fault with 2nd gear.
I have noticed today that when I give it some welly the engine is over-revving, so it seems that the autobox may be slipping for some reason.
Spoke to an autobox specialist today & he says possibly a servo fault but won't know for sure until he's road tested it. So it's booked in tomorrow morning for a road test, so should know after that how much lighter my wallet is going to be

Update....had the car road tested this morning by an autobox specialist & his professional opinion is that the 2nd gear brake band has had it (hence the over-revving (slipping) when it's trying to select 2nd) ....although he says, that as it happened so quick with no warning, then it could possibly be a servo problem ....but I could see in his eyes he was just trying to make me feel at ease with the latter theory.
It's booked in for Thursday & he said he won't know for defo until he drops the sump & has a good look. If it needs a new servo, then it can be done with the box in situ for about £80, but if it's the brake bands, then I'm looking at a £700 rebuild .......although, he said he may be able to adjust the bands to get a few more miles out of it.
But hang on....guess what I found today in my local motor factors.....THIS......miracle cure  , or just more snake oil jollup gunge ?
I've nothing to lose as the car is off the road, so what the hell....for £15.00, if it does what it says on the bottle, then I'm laughing...if it doesn't, then not too much lost

hmmm might be worth a try... where can you get it? it says on this website that you have to buy a whole pallet
let me know how it worked for you... i don't have a problem as serious as yours but it have a time to time leak/drip from under the seal. don't have time to sort it out and it's occasional and not bad... it says on the bottle that this magical liquid also sorts out seal leaks...
if it will work in your case that it might also help me out

just found it on ebay let me know if it did the trick for u. if it really can fix an issue like yours then it shouldn't be a problem for it to fix my inconsistent leak
after all it's harder to fix a worn gearbox then a leaking one

Jon. They also do a product for steering racks which I used. It did work for a while so I guess it has to worth a try. Good luck, Mike.

hi jon
just found this email from bill (stn) from 11/2003.......
Brake Bands shouldn't really need adjusting ..but of course
> not everything that is " supposed " to be ..actual IS .. The
> bands are a metal half ring mounted on a shaft .. and they
> " brake " the rotating " barrel " that holds the clutches ..to keep
> it simple .. obviously that can't be metal to metal so they have
> material on them as do the clutches ..and in turn wear in a similar
> way < not so much though > .. the premise that they shouldn't need
> adjusting is based on that if they do then they have lost material
> and therefore are contaminating ..as a clutch plate would be ..not
> entirely true as there is an amount of " wear and tear " and the

> hope it's fairly clear ......... regards STN .......... Bill ...
hope it helps. as you've said, nothing really to lose now.

Thanks for that Andy, I have had a good look & it's gonna be pretty difficult to get to the adjusters without removing the exhaust etc, but not impossible. I wonder if anyone on here has ever successfully adjusted the bands without removing the exhaust ?

Put the Lucas stuff in today & guess what ?....no difference .......it still slipping when it tries to select 2nd gear. I've not done many miles in it yet though, so maybe it takes a little while to work ....then again, it does say on the bottle 'Results Are Usually Immediate'.
But if it doesn't work, then that could mean good news. This stuff is supposed to coat worn autobox brake bands in a 'polymetric' film (whatever that is ? ) to stop slipping. The fact that it's still slipping could mean that there is nothing wrong with the brake bands & it's just a 2nd gear brake band servo problem.....which is a lot less costly than a rebuild.....
......I live in hope

Hi all. Have a Scorpio 2.3 Ultima. Had trouble with autobox, kind of slipping drive/ overreving engine effect. Looked on this forum and tried cleaning the MAF senser and to my delight it worked. Thanks for all your help. I wish all problems were as easy as this to solve

The problem is now fixed.....& only cost £97
The '2nd shift band servo' seal had blown & it was losing oil pressure in 2nd gear which was causing the slipping. The guy fitted a new servo & all is fine again
Phew, what a relief
