You have to count the flashes. It repeats each code three times. Those flashes are the number codes. All of the codes are two digits. One flash is '1', then short pause and two flashes would be '2'.

It always starts with a code '12' to let you know it is in diagnostic mode and the last code is always '12' to let you know it is done flashing codes.

Yes it screws in on right side of tramission and you will need a 7/8 inch deep socket to remove it. You may be able to clean the old one once it is removed. There is a little ball thatgets dirty and may you can get by with cleaning it. Good Luck. Ed
