Just got this car and was told that the gear change from first to second takes a bit of time which it revs upto 4000rpms before changing into second....but i also have another problem and that is that it does not seem to want to change into 4th, any reason why this could be. Also the overdrive light on dashboard is always flashing even tho overdrive is off

thanx in advance

Don't know who told you, but they're talking bollocks to put it bluntly.
I/my dad have ran a 2L ghia mondy auto mk1 for around 7 years now.
When cold there is slight bit of 1st gear "hang" as it's called, but not to anything remotely like 4K, ours is around 1600/1700 rpm, once warm is fine.
Not changing into 4th(overdrive) is normal for yours, as the O/D light is used as a reporting feature for gearbox faults, that fact it is flashing shows it has a fault.
In your case it may be the usual stator(turbine) speed sensor issue, the plugs break on the sensor, the sensors go duff, around £50 fitted for a new one,(if mk1/2 mondy).
Then it may have another fault as well, the gear change points, when the stator speed sensor is working are electronically controlled by the control unit situated under the main large connector of lecky wires on the box, the good news is these are around £40 new, and a doddle to fit, no setting up, but when faulty these usually cause a massive issue with jumping up/down gears at any speed, rather than what you have.
The best thing you can do is to drive along to a auto box repairer who will drive your car and then give you a likely better definition than over the air so to speak, will save you money long tern.

if it's a mk3 and i'm assuming it is, press the o/d button on the gear selector to see if it goes off or not

then get the fluid changed

if it's not either of these then it's a fucked box, anything over about 80,000 miles and things start to go wrong with them

another mondeo auto box failure,

dizzy-daz

its on an R reg so i think it is a mk3, the overdrive light does not switch off at all, gonna have a look at the fluid today to see what colour it is, how much of an easy job is it to replace?? and how many litres would i need to put in it as i dont have a handbook or haynes manual for it.

thanx darren

im afraid it sounds like its had its day mate, usual mondeo failure mate, new an second hand boxes are few an far between an go for good money so prob not even worth repairin mate, also on a r its a mk 2, sorry to be the bearer of bad news

to be honest mate if the oil is shitty an water like the damage is prob terminal but give it a go u never know, afaik there is no filter

dizzy-daz

whats the easiest way to drain out the old fluid and fill up with new??

liam-rst

iTrader: (1)

there should be a drain plug on the box, usually at the front an usually an 8 mm allen key an im sure u have to fill them thtough the dip stick but dont quote me on that, its a long time since i touched one lol

dizzy-daz

thats cool ive read about needing to fill them up thru the dipstick, just gonna have to search for the drain plug lol like hunting for a needle in a hay stack lol

R reg is a mk2 mondy, if the fluid is as you say brown this indicates the brake bands are breaking up, the boxes are not as bad as everyone says, the early boxes, ie earlier than your one did have many problems, 95% of which were sorted under warranty when new.
Very unlikely that a fluid change will help, a lot of the problems can be cheaply sorted such as the turbine speed sensor, and change switch unit.
Stop wasting your time and go to a trans specialist.
99.9% of failures are caused by excess heat, or neglect, best thing you can do to any auto is to fit a oil air cooler, I've known mondy auto's looked after hit 130-140,000 miles so comparable with a manual, and needn't cost that much more for full recon, obviously dependant on faults, my T5 box has just cost me £580, would have been another £100 or so if he hadn't cut the 5th gear bearing to sort out cheaper.
