3.0 chrysler
Dan, that 3.0 motor in the Chrysler minivan was not a genuine Chrysler built engine...it is actually a Mitsubisi engine, and that engine had all sorts of issues in the Mitsubishi branded products too. There was a multivalve model of that engine that was installed in the 3000GT that turned out to be a total nightmare of issues. The 3.3 liter Chrysler designed engine replaced the 3.0 after all the trouble it caused
Many of the Chrysler products have trouble because of their optical crankshaft sensor according to my next door neighbor who is a mechanic. The front seal of the engine leaks and throws a little bit of oil out once the engine ages slightly. The oil gets dirty, and so does the sensor that is now coated with it. Since the sensor cannot read the crankshaft, the ECM does not have the proper information to determine shift points. The vehicle starts shifting erratically, but most people keep on driving it ignoring the problem because they think a transmisssion issue would be too expensive to repair. At this point however the transmission has not failed yet, but is on the way. Most people end up waiting until the vehicle will not move under it's own power anymore until they get it repaired, but by that time, the transmission is damaged by improper computer operation. Vehicles with bad / dirty crankshaft sensors will also experience poor running conditions too with hesitation, and poor fuel consumption. The sensor is about $50 and costs about $100 in labor to change if you catch it soon enough!
