Hello, i have an LR3 HSE 2005 with VIN SALAG25415A331672. This car was working perfectly until yesterday morning on my way, the car is having diffculty changing gear and would appear it is only gear 1 & 2 that is being selected. When you switch on the engine, a message ''transmission fault' comes up for a second snd disappear and never come up again.
HI,

I am sorry that no one has helped you yet. I just came online and saw your question.

Ok, based upon the symptoms, the possible causes are shift solenoid fault, pressure switch fault, transmission rpm sensor, or internal fault.

At this point, the control module needs to be scanned with diagnostic scanner to retreive fault codes, which will tell us the area of concern. Once you do that, you can post the fault code and I can narrow it down more

Appreciate you for provide further insignt based on this information

Hi,

Ok, every cylinder misfiring, along with the lean condition points to either a weak fuel pump or air intake leak.

The fuel pressure needs to be tested and if under specs, replaced. If ok, then air intake tube, throttle body, intake manifold gaskets, and vacuum hoses all need to be tested for leak and repaired as needed.

Finally, there is the code for the brake switch, which is above the brake pedal. It should be tested and wiring tested and replaced as needed
