Thread: TD5 Discovery II stuck in 3rd gear

Hi, are the M & S warnings working on ignition self test?

Yeah, they come on fine as the key turns and disappear once motor starts.

Then it's or a mechanical fault or the ECU is missbehaveing cos that 3'rd gear thing is classic limp mode operation but in this case the warnings should be on intermittently...you should do a proper oil and filter change though

I have the beast booked into Wyong Automatics which is where English Auto sends all their gearbox problems to, on Monday.

It appears from speaking to English Auto, that they believe one of the gearbox "controllers" in the box itself may be the culprit.

Does anyone know anything about these? Are they accessible from through the sump without removing the box?

Are these like the solenoids in a ford auto, which can "burn out" and simply need to be replaced?

Just trying to work out if this is something I can do or whether it's just easier to let the professionals do it.

Cheers, Pete'

Usually a component failure within the valve block would give you the flashing M+S and log a fault code, that's why i asked about the self test... it is accesible without removing the box

Well the saga continues....

Rod at Wyong Automatics have been through the box, checking all the solenoids (they have a machine that they hook up to them), and they are all fine. They checked the XYZ switch (they called it something else but I can't remember), and that's fine too.

I was sorta hoping it was the solenoids....

Update soon. Hope this will eventually help someone else as it's a nightmare for me!!
