hi there

if the light flashes, then it indicates an issue with the gearbox. you need to check it out asap.

check the level/smell of the fluid. get the 'box up to temp. with the engine running, cycle through the gears 3 times each. again with the engine running check the level.

you also need to get it scaned as an error code will be stored.

ok so this morning i take out the maf sensor and find that both the wires have a black coating on them that is about 1 to 2 mm thick in the middle covering about a 1/3rd of the wire dose anybody think this could be the problem and if so how do i cleen it without breaking the little wires!!!!!
i also looked at the g/box oil the leval seems to be ok after priming it 3 times the colour after wiping on a white lint free cloth is a very light brown like new engin oil{not like old burnt oil} smells like g/box oil from what i can remember from my old granada auto
it has no bits in it ie it is clear
thanks

get your self a can of carb cleaner and spray into the hole where the wire is, this will clean the wire, as for the fluid it should be red not brown
red------------------good
brown----------------bad
black----------b****red

hi there

a light brown colour is an idication that it's at/past it's sell by date. a change of oil/filter is about £100 at a auto box place.

ok went to halfords and got a can of carb cleener and .............................well lets say it drives like a new car the gear change is crisper and tickover is better
i did notice that the gear change between 1 and 2 is ok but from 2 to 3 the revs rase slightly and it seems to slightly slip in to gear can this be adjusted bye the tension bolt on the box

hi there

i wouldn't adjust anything just yet, wait a few days. the o/d light flashed because it saw a problem. as i said, wait a while and see if it was just a dirty MAF that caused it.

re the slip in gear changes. it's does a sort of slip as it changes, to make the change smoother.

oil and filter change is only £59 at the mo, from most auto garages, i think they are all fighting for trade
