Title: autobox acting oddly
Post by orsts2 on Apr 18^th, 2006, 11:59am

hello

i have have 2.0 16v automatic -95 model scorpio and i was wondering what is wrong whit it´s gearbox...

when i drive 75 mph there should be around 3000 rpm
but the gearbox changes to smaller gear and back to bigger geat and then again back to lover gear an the revs rise and drop rise and drop... seems like it cannot keep the final gear on it always drops tote smaller one...

i changed the gearbox oil and filter, that did not help...

Hi, Get the powertrain computer read first to see if there are any codes present , if not Im afraid its transmission rebuild time. Regards, David

hi there

work your way through the fault finder list, but first of all, give the MAF a clean.

first off welcome to the site

second. first off clean the MAF (like scorpio_man said) it's the bit where the multi plug goes in the air tubing from the air box to the engine. you'll need to remove the air box to get at the bit you need to clean (using somthing like carb cleaner)

third. what colour is the auto box oil? if it's red it should be fine, brown means its over heated and possible costly damage has been caused

i cleaned the MAF and now it revs nicely to the redline and doesn´t missfire at all as it used to do... so one problem solved thanks to you guys.

the gearbox is still acting oddly on motorway speeds..

gearbox works fine when you are accelerating 100% it changes gears like it should and works fine. But when you drive normally like steady 70 mph the engine is reving about 2600 or so... suddenly the gearbox kind of changes to neutral... then off course the revs rise and when the revs hit 4000-4500 it thumbs the gear in and the revs drop then this hapens again revs rise and then thumps gear and so on and so on...

the oil in the gearbox is new and the old oil that used to be there was pink

Might be something as simple as the VSS playing up worth having a look at the wiring and checking that. The EEC gets all the informationabout speed etc from the VSS on the side of the box .

Also check the wiring loom from the box.
