I am not 100% sure that all TH400's have an electric kickdown, but everyone I have seen does. Make sure everything in the system is operating properly.

Play around with a google image search of TH400 kickdown and it will show you where the sensor is located on the transmission and also look on your throttle linkage to see if you have a switch. If you do have all of this, make sure it is operating properly.

This may not be your issue but you can rule it out if it is functioning properly.
