Sorry, Bruce, but that casting number does not translate directly to a part number that can be crossreferenced! But, my parts catalog doesn't have any 901/911 transaxle pics in it, anyway.
And, about that differential, the '69-'71 spec book does not have any differences in the ring gear setup page! Presumably, that means no changes over the '69-'71 span of the change to go to the pull-type pressure plate for the 2.2's ... the linkage changes for the 2.2 clutches is the only real change that warranted the designation change to the type '911' transaxle! ------------------ Warren Hall 1973 911S Targa |

Thanks Warren, How can I determine what the gear sets are in there?

Look for the Sreial Number and 'Type Number' on or near the bottom rib ... 901/xx or 911/xx, where the xx will be listed in the spec book with ratios equipped from the factory. That is, except for custom ordered gearboxes designated by a special prefix code in the serial number!

Bruce,
That would be a four-speed, standard ratios, for a '69 912 ... the ratios, for a 902/14, from my service manual chart are: 1st -- 11:34 (3.091:1), 2nd -- 19:32 (1.684:1), 3rd -- 24:27 (1.125:1), 4th -- 28:24 (0.857:1) ------------------ Warren Hall 1973 911S Targa |

912 and 911 transmissions are basicaly the same thing correct? The differential from this 4 speed should work in the 5 speed correct?

Bruce,
Yes, on both counts ... originally, the 912's were only going to have four speeds, and a special version or the 901 was developed and named the 902. But then the planners and bean counters got together when the cost-reduced 911T was built, and there have been 902 transaxles used in 911's and 901's used in 912's. Confusing!!! ------------------ Warren Hall 1973 911S Targa |
