I have a 98 XJ Classic.  The check engine light is always on with these codes-P0135 O2 Sensor Heat Circu1t Bank 1 Sensor 1- P0700 Transmission Control System (MIL Request)-P0715 Input/Turbine Speed Sensor A Circuit.  I did the dumb thing and took it to a local shop (Hampstead Performance)  I'm naming mane because they charged me $276.23 for 1 hour of diagnostic time, 1 hour of labor, 1 oxygen sensor.  Check engine light is still on and the P0135 code shows back up.  Step 2 I bought the O2 sensor and put in on myself, reset the codes with my scanner and the same fault came up P0135.  I also bought a speed sensor and replaced it myself, with the same 2 codes coming back after I reset them?!?!?!?!  My problem is that I have to pass emissions or my tags will be suspended.  And I know about the spending the $450 rule in MD.  Im about $100 away from the $450, but would like to know why the HELL I cant fix the F$#%ing problem and get rid of the codes!!!!!!!!!  HELP
