Hello, thanks for posting

The shift solenoid E is for the lock up torque converter, it locks the torque converter at higher speeds, most of the time it's not the solenoid that is the problem but it could be contaminated transmission fluid that has distributed metal particles or clutch material into the fluid, the first thing to check is the fluid level and the fluid condition, if the fluid is dark and dirty it may be a good idea to have the transmission completely flushed using a machine, this cleans out the torque converter and replaces the fluid completely, to me it's worth a try instead of taking things apart to replace the solenoid which may not even be the problem. If the transmission is shifting normally and is not slipping this may be all that it needs right now.
