My '05 TJ started slipping out of gear. It's an automatic. She has 130,000 miles.
She's going through a wear cycle and has many codes:
-----
P0871 - Overdrive hydraulic pressure switch circuit.
P2096 - Downstream post catalyst fuel trim system 1 lean. (TSB?)
P2098 - Downstream post catalyst fuel trim system 2 lean. (TSB?)
P0700 - Transmission malfunction present.
P0871 - Transmission fluid pressure sensor / switch C circuit range / Performance (pending).
-----
I was working on 2096/2098 when the transmission slippage began.
I changed the transmission fluid and filter, but there's no change.
Maybe it's a common problem? I'm hoping someone here can assist by cluing me in on what to check etc.. I have fairly limited tools.
I prefer to start with the simplest things first.. For instance, could it be a hole in a vacuum line or a loose sensor connection? I just don't know where to start looking!
