I've ordered a new governor pressure solenoid, governor pressure sensor, filter, and tcc solenoid for my 99 R/T. I was going to have my transmission shop change them out. I noticed some leakage on the driver's side area right above the nss which appears to be the shift shaft seal. I was reading the fsm and there's no specific instructions to just change the seal. But it's listed in when removing the valve body to check the condition of the seal and replace if necessary with a 15/16 socket. I'm guessing you have to have the valve body out for sure? If I end up having the shop replace the tcc solenoid I may as well replace that seal. I just hate having them take out the entire valve body when I just need a governor solenoid and sensor. But they told me since it's not a 99 transmission and the pressure sensor is different it's not communicating with the computer so I need to change all three parts.
