I would be driving along and all of a sudden the neautral light starts blinking and stays it top gear. I can only use 2nd and 3 rd by using it manualy. if I switch th engine off and back on it works for awhile and then starts again.
Hi,
Mitsubishi's electronic transmission has a built-in diagnostic....which is indicated via the 'N' (Neutral) light on the instrument cluster.
When the diagnostic computer detects 2 or more of the same fault (which does not rectify itself), then the transmission goes into "LIMP MODE' - this is to protect the transmission from further damage, but will allow you to drive in 3rd gear.
First, we need to ascertain what "sequence" the 'N' light is flashing:
If the N light flashes ONCE per second, then there is an abnormality with one of the transmission components, and will require accessing the computer for further trouble codes.
If the N light flashes TWICE per second, then the transmission fluid is overheating also - pull over, let engine idle in N for a few minutes to allow it to cool down.
Turning key off will only reset the computer momentarily, until and the transmission goes back into LIMP MODE again, so further diagnostic investigation will be required.
If you are technically inclined, i'm happy to explain how you can access the computer codes, without a code reader.
Let me know...
Cheers,
Hi Scott, I know this post is very old, but any advice you could give on how to access the transmission codes would be greatly appreciated!! I have a 2005 Galant which is doing exactly what you mentioned above.
Please tell. How do i access the computer without a scan tool
I have a 01 diamante that the trans is in limp mode. Need help
