JO code trans were W31 only in 69-70 model years and not available for other power teams unless option W31 was ordered. Also, most people do not know that a high stall converter was used from the factory 2,600-2,900, W30 s had 2,300-2,600 stall. These "special" converters were not available "over the counter" at your local Olds dealer. Why? I do not know. These converters were actually "rejects" from the Buick trans line.
If VIN is stamped on LH side of case and matches vehicle VIN I would go to the bank that is a legit W31 F-85. Do not refer to the "governor cover" which has the trans coded stamped in the cover. The covers are held in place by a snap ring and therefore can be removed.
There are several items done when a W31 option is ordered that is not listed or discussed in magazines or Olds literature. I know them all and no I will not reveal these items/parts.

Things like this need to be shared somehow. Otherwise when you die, so does the information...

Geeze, you can't take it with you. It's not like it's for W-30's.
Or are there some things hanging out on those that we don't know about?

Another clue would be the punched holes for the W-31 emblems and factory markings on the inside, if original fenders.
