Overdrive

kamzack

 Recently overdrive quit in my 50 Commodore 8. I've swapped both governor and solenoid, no change. Bench tested gov I took out and it works. I can hear relay click in and out. I drive it regularly but not  w/o overdrive, too many rpms. Help, please.

Go to my website - see signature block for url. Select, transmissions, multiple OD manuals there.

Look at a Hudson Mechanical procedure manual, they have about 16 checks to perform to troubleshoot the Overdrive.
