I have had mine for over 2.5 years now and about 1yr into owning it i felt this hard shifting between 2nd and 3rd and my lights were dimming (it happened late at night) when u turn the engine off its ok...but it came back every week then every month then disappeared. just last week...it came back...so i pulled over shut off the engine turned it back on and went on with my day...the problem hasn't returned...should i replace the mode position switch? it seems to be a very common issue...
