XJ code monster
Hey all I pulled some codes after my auto trans only had 1st and 3rd gear, if anyone knows anything about these feel free to speak up
The list:
P0123 TP sensor circuit high input
P0107 MAP sensor circuit low input
P0320 no crank reference signal to pcm
P0138 o2 sensor 2 circuit short to voltage
P0700 read fault memory of control unit etc
P0753 A/T 3-4 solenoid/trans relay circuit failure
P0715 A/T input speed sensor circuit malfunction
the last two seem to be the most important, I'm not sure if any are related, I would really appreciate any help 98 XJ auto trans 4.0

Honestly, you need to clear your codes and start fresh. See which one returns first and go from there. What were your symptoms before the transmission started acting up?
P0320 no crank reference signal to pcm - Extremely Important btw!
