Shift solenoid e is solenoid SL in the valve body and controls the torque converter lock-up. If the solenoid fails, it fails safe so that you will end up with a 4 speed transmission without a lockup torque converter. To check the solenoid, you will need a replacement transmission pan gasket and some replacement ATF (Check to be sure, but I believe your car takes Dexron III). Drain the transmission pan, remove the pan. If you are in the rust belt, be careful removing the pan bolts as they may be rusted. If they are rusted, apply a rust penetrant like PB Blaster, wait an hour, apply again, then carefully loosen the bolts. Remove shift solenoid SL from the valve body and measure resistance between the two terminals on the wires connected to the solenoid. It should measure between 11 and 15 ohms. If that checks out, apply 2 volts to the 2 terminals and see if it makes a clicking sound. If the resistance is not correct or if you do not hear clicking, replace the solenoid. Before you replace the transmission pan, take a look at the screen. It will probably be clean, but while you are in there, looks are free ;-) When you replace the transmission pan, tighten the bolts finger-tight, then tighten in a star pattern and refill with ATF.
