Transmission Clunk from 2nd to 3rd

[Y33TREKker]

Hi guys.

Im Gutted....
I only bought my vx a few weeks ago and driving home from work this morning (I work nights) I felt a clunk going up through the gears, then the red CHECK ENGINE light came on. My heart sank and i thought ohh... s#!t.
I'm not going to pretend I know anything about the mechanics of a car. I'm a nurse for God sakes, I fix people not cars...lol

Anyway, I carried on crawling about 30mph as i only live 5 miles from work. 1st to 2nd was smooth but 2nd to 3rd felt horrible! A large clunk while it jolted into 3rd, same going down from 3rd to 2nd.
Got home and straight away on here searching to find out what's wrong.
More than likely looks like its the mode position switch (whatever that is) but you guys seem to think the LEDs should flicker or go dim etc etc when I change gear mine doesn't? Everything works spot on.

Worst thing is I live in England, United Kingdom. So the chances of finding a mechanic that even knows what a vx is never mind how to fix one is rare!!!
Eg I phoned my local this morning and he was like, "what's a vehicross?"
Omg, doesn't matter thanks for your help...lol

Any ideas?
Anyone
:-(

You might have your local give this place a call and ask if anyone is still there who knows the Vehicross who could offer some insight. They used to always have at least one or two VX's on the lot, and I even sold them a few spare parts a couple of years ago.
