I have had a good tree weeks, changing the front and rear differentials, the oil and filter, the fuel filter, the transaxel fluid and the transmission fluid using the the "Hoot" method. Used synthetic in the diffs and transmission, GM's approved fluid in the transaxel, and dino in the crankcase. Saved the tranny for last. Do not, I repeat, do not take off the wrong cooler line. Don't ask how I know this. :eek: Thanks to this forum, I had clear instructions to do all of maitenance items and saved a ton of money. Now if I can just figure out how to get the fuel filter BACK ON without pulling the wheel well liner.
