This is a 450es, I have checked everything over, did all diagnosing of the es and cant figure it out, it will shift fine through all gears and back down to neutral, the only problem is when you go in any gear and are reving high, not to the limiter though, it will have 3 dashes across the gear indicator and then wont shift down untill you turn the key off and it seems like it resets itself. Please help

I just took it for a test drive, ok I dont need to be reving the quad to not shift down, it seems like more in fifth gear about half throttle for approximately 30 seconds or more than it will not shift down, the gear position still reads 5, but it will not shift down untill I turn the key off then on. I dont know if it makes a diffrence that it is a Canadian model or not, but the speedometer only reads km and it doen not even work, it reads 0 all the time, Any thoughts on why it does not shift down.

Ok here are my thoughts, I seen a guy ask if the speedo works properly, it does not work properly, it does not read mph, it reads 0 even at high speeds. I did all test and the test results say I need to replace the ECU, but I think I should put a speed sensor in it because it is the cheaper way to process of alimination.
