Hello again -

Thank you for your reply.

Ok - this fault can be caused by one or more of several causes...

So - start by checking what you can on a DIY basis - and that is the transmission fluid.

Check its level - if its low - you meed to top it up and re try... After you top up ( if you do ) re drive it - and re check the level - top up again if needed - and re do..

First though while checking the fluid - it should be a nice red / brown ish colour - If its black.. and / or smells bad.. ( other than a nice oil smell ).. then that indicates faults in the transmission....

The way forward then would be to drain - flush and refill the transmission ( this is best done at a Auto specialist as they have the equipment for the flushing ).. and then re try.

Bad fluid changed - or just topped up if too low, will often cure what you have...

IF not - then you have an internal fault in the trans... torque converter or solenoid faults , clutch band issues and so on usually especially if you have no fault lights on which would normally indicate an electronic / command / control issue... at this point again - you really would be best advised to use an Auto Specialist to check it out - you can do nothing more on a DIY basis Im afraid.. They have the test equipment needed - and the knowledge to properly check and effect a repair.. rather than replacements which general garages tend to do - so its a much cheaper way...

So work through as above on this one.. let me know how you get on.

Do let me know if you need anything else at all -

Kind Rgds - MIKE.
