TH400

A 1966-68 CT TH400 code on the Passenger side tag is for series 10 & 20 Truck application.
In 1969-70 there was no CT suffix tag.The series 10 & 20 Truck became CJ.
Just to be clear,I am talking about the silk screened suffix tag on the Passenger side of the transmission.
If a Transmission shows CT on the Drivers side,with 5 non VIN# related digits after it,that is a SERVICE REPLACEMENT coded Trans.,& the same as a CE Coded Engine block was defined.
