Ive been getting a hesitation between 40 and 50. Hooked up scanner and p1740 code was shown. So I put a new tcc solenoid in and it did nothing. Still hesitation between 40 and 50. Also no misfire was detected. Could it be the overdrive solenoid or something else. Yesterday after I replaced the solenoid it did great for a 30 minute drive home. Today it did great on a 15 minute drive in town. But on the way home it started doing it again. Any ideas on what to look for now.

 

That code seems to be for a transmission fluid pressure sensor/switch. I would check transmission fluid levels and replace the TFP.

 

Do you know which engine you have ? Take a picture, someone here should know.

 

Its the 5.4

 

You still have a low grade misfire. The count isn't high enough to register In the KAM yet.

 

Ok my friend has a good scan tool. I usually take it to him when it acts up. It reads the misfire when not throwing codes
