Overdrive Transmission Replacement

Q:     I have a question about a transmission. Is it possible to take out a 1973 four speed transmission and replace it with a transmission with overdrive? Other than an electrical connections of course.

Tommy K.
Virginia Beach, Virginia.

A:     The simple answer is YES!! The drive shaft is the same length. The gearbox mounts are the same. The reverse light wiring (Green and Green/Brown) is the same. You can move your seat belt warning switch from one remote control housing to the other (if you wanted to – most wouldn’t bother).

The BIGGY here is to test the 3-4 lockout switch TWENTY times to ensure it goes continuous in 3 and 4 (or, if it’s a later gearbox (sidefill) maybe just 4th).

Change the front and rear seals and ALL the O rings before you install it.

Hope this helps!
