If you guys ever did and oil change and added laucs oil to help stop your oil pan gasket from leaking you will also experience as if your cam sensor is no good...so if you have done an oil change recently and you are having the issue to where your rpm gauge isn't working and your transmission isn't coming out of 1st...try changing your oil 1st...the whole reason is because the lauc oil is way to thick for the sensor to get an reading off the cam gear...
