Initially there was a rattling sound when the gear selector was pushed a certain way. The Mitsubishi tech's would not even look at the problem till I figured out how to reproduce the noise for them. Then on long trips the a/t lamp would come on. I would pull over and let the engine cool the proceed until the next a/t incident. Some of the problem was caused by the transmission having bolt heads rattling around inside the trans housing. Other problems were caused by porosity of the trans bell housing leaking trans fluid. Mitsubishi 'fixed' the leaks and bolts rattling around inside the trans, but now on trips of 100 miles or so when you accelerate from a stop during the rev up to shifting around the 2nd to 3rd gear shift the tach will indicate a high rev then fall back when the shift is accomplished by the trans. The vehicle will 'buck' in response to this shifting anomaly. This effect will not happen unless the engine has been running for an hour or so. I now no long take this vehicle on long trips unless compelled to do so.
