Error Code Help

I have a 2005 LJ 4.0 Automatic. Check engine light came on and went off a bit later but got the error codes P0700 and P1755. Took it to auto zone and had them scan it the first says transaxle control system fault, and the second transmission throttle valve control circuit. Any help would be appreciated.

Check your trans fluid? When's the last time you did a transmission service (flush, fluid change, filter)?

Have the codes cleared and if the light comes back on check to see what code comes up. One of the codes may be old and not applicable any longer.

Thanks for the replies. Trans fluid level is good. I have noticed recently that the trans is slipping a bit in 1st when its hot. Looking at doing a fluid change on everything soon. Just wasn't able to find a lot of info on those codes from google.
