Hi, im a newer member and i just recently bought a 2000 25004x4 auto, with 47k miles. Already the lift pump was replaced (on the 5th day with truck) and now the truck is acting up if speed is any higher then 60mph. It acts like its hitting the governor no slip but, like a bog whenever it hits 2k rpm, is this a transmission issue? Also the truck has the banks ottomind box and bighead wastegate actuator.
