many thanks, will do later today,thanks :)

ok more help please,
today i bought the trolley jack,axle stands etc and went to do atf check myself.
i done excactly as previuosly described and when i took plug out even with cat lifted a fair amount started coming out so i pushed in filler and got more in, i reckon i lost about 1/4 litre but got 1 in.
took it a drive, still wee probs,im no mechanic but now i believe its slipping gear rather than anything else.
the reason being when driving 3 times it did same it changed up gears all be it not really smooth but as i drove along revs went up and car now gone into neutral so i brought lever back to 3 and then put back in drive and off it went.
hope this makes sense to someone?
it drives ok using lever in 1/2/3 and when problems arise im almost 100% its going into neutral neutral.
thanks

the atf level needs to be at the correct hight, engine running car level, select all gears ,while stationary of course, let the fluid poor out of the level hole until it stops, that is then the correct level.

You cant just chuck any old amount in.

What oil are you using?

did you have the car level at any point with the level  plug undone so the excess can drain out?

its a level hole not a fill hole, so

jack car
remove level hole plug
start engine
slowly drop the car down via the jack until its level, or if the drive is level just let the car down slowly.
allow the excess to run out of the level hole until it stops and has found its own level.
switch off engine.
then re jack the car and refit the plug.
dont burn yourself on the exhaust.
level should now be correct

if there is no change, you need Hotel 21 and tech 2, and posiblly next step is to service the atf. remove the 2 sumps clean filter and check for debris etc refit anf re fill with new atf.

If the atf has got hot or is over 80k old it will probably be fubar. It does not last forever.

And potentially curable by topping up the atf

ok re read, he's not sugesting over filling, but that the level may be low, hence topping up (to the level hole)


What colour is the old oil coming out? is it black? or is it as red as the new stuff going in?

ok,once you have the level correct then there is no more you can do at this stage.

The fact the box is fine while changing manualy sugests the box is mechanicaly ok IMO, although you mentioned debris which is concerning.

Get the car to Hotel21 next, and go from there. See if tech 2 shows anything, hopefully a cam or crank sensor fault in the engine ecu or a bad solenoid in auto box.

good afternoon folks,
now then ,today i done again as directed down to the T.
i ran the car till temp up, jacked car up at drivers side, put tray underneath and undone plug.
there was about i guess 1 - 1 1/2 litres atf come out in total as directed i slowly lowered car till levelled out.
the atf stopped whilst waiting for it to stop i worked the gears back and forward using all gears. then jacked car back up and put plug back in.
i then took car for drive and seemed ok at first used auto then 1 2 3 gears but after about 10 mins whilst in drive the light came on and the car went into neutral as could rev but nothing happen, althoughh i could move gear lever and would go into 3 2 and 1. i then put back into drive and got small clonk from back and then obviously decided to go in gear but only 3rd limp mode,. i could still use 1 2 3 though,it only stayed in limp mode in drive.
i stopped car turned off and restarted car light went out and put into drive and away she went again.
to some this may seem abit strange to me its driving me to valium.
i have to say that before i removed the surplus atf the light had not come on since adding some,although the car still played up.
i am confused as to how come gears work 1 2 3 but not in drive?
does this mean more electrical than mechanical, h21 bruce when you read this can you let me know if you can put on tech2 again? see if any other codes appear.
many thanks.
last thing is although im in fife i will be going on job to ireland next sunday from carnforth in lancashire if there are any great mechanics out there i will be away for a week if anyone would like to fix this ? please !!!!
your views would be appreciated.
thanks to all!
