99 3.2 TL w 102k miles. Yesterday the CEL came on and today Autozone pulled 3 codes: P1456 - Evap System Leak (usually gas cap)
P0401 - EGR System Fault
P1739 Slip solenoid AT 3rd clutch pressure switch circuit fault.

Is it possible these are all related since they all came on at the same time? I find it nearly impossible that 3, or even 2 unrelated problems would surface the same day like this.

I would appreciate any insight that could be shared on this unlikely situation. Thanks.

Clean the EGR port. If you look in the DIY thread there are directions to cleaning it. Double check that the gas cap is tight. Neither of those would have caused the trans code. Trans failures are a problem on these cars so its possible its about time. Pull the clock backup fuse and reset the ECU and see what codes come back after doing what i mentioned.
