Where do i look for the year of the trans?
 
There are numbers on the edge of the casting right above the pan. You can cross reference your tranny numbers with some online databases of casting numbers. It should narrow it down.
 
There is a 10,000 day calendar date on the side by the oil pan rail. Yes, that is right, Mopar used a 10,000 day calendar for that. Why, who knows. Someone was having fun...
 
# is where by the oil pan? driver side? front? Where? thanks
 
Date coded case or what is inside it? Many older 727s have the '71 and newer pump/input shaft/stator support and wide band front drum

From a for sale post on a trans

I dont see a PK number or date code

Some sources claim there were no consistent date codes prior to 1969. The raised casting dates on the individual parts give a clue to the approximate year.
 
I don't know the date code numbers, but the reverse/neutral switch is a 1971 and newer type, which means the shift selector rooster comb would have to be compatible with the switch.
 
3 prong NSS is '69-up.
 
It looks like the numbers are removed or painted over on my transmission is there an easy way to tell which neutral safety switch I need? Trans is in the car so hope I can tell using these pictures.

Look thru the hole and see if u just see metal or plastic. Plastic is the 3 pin. Metal is the single pin. Ofcource it depends on the year of your vehical. 68 and back is single pin. 69 up is 3 pin. U may have to mix and match cause the valve body may be a different year also. Kim
