CEL light bank 1 sensor 1

ok my friends, I got a CEL light, took it to advanced auto, code says P0751, 02 sensor, bank 1 sensor 1 and shift solenoid. I've have seen on here to order the 02 sensors from ROCK AUTO (and REPLACE both bank 1 & 2).....but I have not seen much on the SHIFT SOLENOIDS...anybody care to share some advice on how/where to fix these issues?....instructions for replacing shifting solenoid and 02 sensors???....please????

thanks anybody!!!!

 

taken from another thread...."shift solenoids are internal, when you pull the pan off they are right there"...can anybody point me to some more detailed instructions?

 

I can't say anything about the shift solenoid but the o2 sensor just un bolts and follow the wire and un plug it. Than out the new one and plug it jn
