Update: Ran scan tool on Truck. Trans is commanding for fourth gear but seems to not have line pressure enough to engage overdrive . Turning into a real headache.

 

That's true. I bought a K&N filter for a K-2500 and it zapped my MAF with oil. It was pre-oiled BTW. I cleaned the MAF off with brake cleaner, and its still running fine to this day. Personally I dont think the the K&N oiled filters should be used on a car driven on the road in normal non-dusty condition, as its just a waste of time and money, but they are great for lots of dust/sand when off-roading, as long as you oil it yourself and let it sit for a day or two to drain any excess oil off the filter.

 

2003 should be fully electronic

 

I am going to test Servo housing travel today to see if there was any internal damage done to transmission, oil looks good . Wish me luck

 

It might be a shift solenoid
