This wont be a fluid level issue.This is a fault with a component in the transmission.Since you can cycle the key off and back on again and it resets the fault this may be a fault with a component like the valve body or transmission shift solenoids needing replaced.You will need to have this checked/tested further to locate and repair this issue.

Hi PeteThank you for the information. I take it I will be able to connect a normal scanner or is it some kind of transmission specific device that is connected directly to the gear box. I also wondered if it might be an issue caused by a dirty transmission filter causing an oil pressure fault. Once again thank you, ***** ***** on this matter is really appreciated as auto transmission boxes like this aren't my bag although it's always good to broaden ones knowledge.

Your welcome

Usually a normal scan tool can be used but it has to be one that can read all computers in your vehicle to then be able to diagnose it fully.

Usually it wont be a dirty filter at fault here or dirty fluid.This sounds more electrical like a sensor or solenoid at fault.

If I do find fault with these components is it a job I can do myself or would it have to be dealt with by an auto transmission expert. The reason I ask is that I'm wondering if it would be beyond an economical repair for this age of car. I.e. Would the cost of the repair be more than the car is worth.

It depends on the component at fault.Some can be replaced with maybe $150 in parts and some can require over $300 in parts and the transmission/gearbox removed to then replace it which can cost over 8 hours labor time in which it may not be worth repairing.It all depends on your decision if the vehicle is worth repairing.

Let me know if you need anything else and feel free to rate my help here or above ( should be a link to click on ) as this is how I receive credit for my time, this can be done at any time and you can still come back here and reply if needed.Your 5-star rating is appreciated

Thanks Pete
