are you sure its shifting out of third. My check engine light came on about 2 months ago and it was due to a problem with my ignition. The symptom was that my truck would simply refuse to shift out of third gear. This created very slow take-offs and high rpm @ speeds over 45 mph. Mine was luckily a quick fix... hope this helps...
