2008 Mazda 3,2.3, AT, PO720 code
Hey everyone,
First post so have a little patience with me. I am not a mechanical or proactive person. Not a lot of preventative maintenance on my ride. Too broke.
Anyway, Tranny having issues while driving. All speeds. It is having difficulty staying in one gear. Engine light will come on and AT light comes on... the lights will go off after it is shut off. I had a shop run the codes. It came up with PO720 VSS circuit malfunction. They recommended these two sensors, (FN-21-551 & FN01-21-550).
My question is...Before I change those out should I change the fluid and filter ? The vehicle has 170k on it. Never had fluids changed. Color of fluid is dark. Not red
Am I too far gone ?
Thanks for the feedback. David
