Be very careful of servicing these transmissions at a fast luber. The newer transmissions require different fluid,this is why it looks discolored. Outside shops do not have different machines to perform this so called flush and the fluid could be contaminated and cause internal damage. Go to the dealer and have them explain. It may only be a drain and fill procedure , and be cheaper. 150 k is alot,I recomend 60k.Besides this peticular trans has a built in screen.The trans must be dismantled to be changed.
