    Scanned my "Check Engine" light and shows B1/S1 O2 sensor is bad. I went to change it out the other day and it appears the connection is made at the top of the transmission. I have tried from every angle I can think of and can't seem to get my fat meat hooks in to access the connection. Any advice on how to make this happen. I really don't want to take it in and have to fork out $100+ in labor to have someone else do it.
