Reading through the proceedure for the test I realized there is no manual switch on the shifter. I did the test anyway but the light just stayed on the entire time. On the website with the proceedure it says newer models "may" require a scan tool. So I'm going to borrow one from a friend and give that a try.

Ok I got you now. Its a similar thing on my Land Rover but you jumper the connector to get the number of flashes to retreive the code. When I do the handshake proceedure I'll then have the code for the problem. Thanks for clarifying.

Unfortunately it doesn't have the code for 16 flashes which is what mine is indicating. I have a code reader on the way so I'll try to check it that way. Thanks for the info.

I know this has been beat to death in this forum and I have searched through the old forum topics and can't find a definitive answer to my problem. My friend has a 1997 Legacy wagon with an auto transmission that has an AT oil Temp light that flashes exactly 16 times when the car is started. It also seems to have a shifting problem but not all the time. Shop says tranny is bad but they never addressed the flashing light. Do I need to download the OBD II codes to figure out the issue or is there a proceedure to figure out what may be bad on the transmission without downloading it? I cant find a list of codes that addresses the 16 flashes directly. All my Subaru's have been 1990 or earlier and manual transmission. Thanks.
