Transmission selector not working

[dickinsond]

After towing a large trailer with my Model T onboard, the 4x4 high and 4x4 low warning lights flash for 2 or 3 times every few minutes, and the Auto, 4x4 high, 4x4 low selector switch doesn't work has anyone come across this before? The car is a right hand drive U.K. model if that makes any difference.

The transfer case has a problem, it could be the shift motor or an internal problem. Could be electrical also.

Try disconnecting the NEG battery cable for a while. If that no good pull the sensors (IIRC they are magnetic, and can become fouled with metallic fines) and clean them.
