The transmission was rebuilt in Oct. 1999, the transfer case in Nov. 1999, new motor in Aug. 2001. I thought I was good to go. No more problems for a couple years any way. Shortly after getting the engine in I noticed very rough shifting between 2nd and 3rd. Took it in, they opened it up and split the filter and found CHUNKS!!! Best case senerio $500 to $600. There goes the new tires. Had to share. Blazer has a new name. PIT (money pit that is).
