Was going to get the trans. flushed on my wife's '99 Olds Aurora. 4.0L Northstar engine, 4T80 trans. According to alldata and the factory manual, the trans. oil cooler is in the right hand side of the radiator and the eng. oil cooler is in the left hand side. My radiator only has a cooler in the left hand side, nothing in the right. Jacked it up and followed the lines back to the trans. So the trans. cooler is definitely in the left hand side and no lines from anywhere going to the right. If there's any GM techs out there who've worked on these cars, does this engine even have an oil cooler? Is it the one that is a small water to oil heat exchanger bolted to the block like on the 3.4L DOHC engine? The factory manuals and alldata are both incorrect on this installation. Thanks for any help.
