I have an overdrive sol with 4AR10B-62 stamped on the cover. Can anybody tell me if that is a 6 volt or 12 volt unit?
Thanks for reply , hopefully somebody has an application chart , I believe thats the Borg-Warner number.

Not trying to be smart but have you tried it on a battery? I had a solenoid on a 53 trans I picked up that I thought was bad, after finding a replacement I tried the old one on 12v and it worked ever time. Someone in the past had replaced the 6v with a latter 12v solenoid. The one I'm using now is a delco, as long as the shaft length is the same all manufactures should work.
 
A 12 volt solenoid will have 12 volt stamped into the end bell (cover).
6 volt will have have nothing.
 
yes I did test it with a 12 volt battery and it works fine, however not sure if it will respond with 6 volt power source. I don't have a 6 volt battery to test it with. So I thought someone on FB might have an application chart to just decipher the part number stamped on the cover.

The part number is likely Borg Warner since it has R10 in the number. I have no idea what the dash number means. Ford wasn't the only company that used the R10 overdrive. The length that the operating plunger protrudes is the most important dimension when dealing with these solenoids. Older 6-volt units will generally work on 12-volt but I don't know if a 12-volt one will work all that well on 6-volt. It has to push out enough for the holding coil to kick in so that it will stay in overdrive without using too much current.
 
I agree with post #4. The ones that I have seen are stamped 12V and a part number and the 6 volt ones just have a number on them.
