Part Number Cross Reference

[Alan Nicholas]

Gents & Ladies.
Is there a cross reference table for part numbers for transmission gears? In that GM/Chevrolet parts have different part numbers than gears that have been manufactured by the Perfection Gear Company (and I assume any other after market parts manufacture). I assume that somewhere there is a conversion table, because to manufacture after market transmission parts for various vehicles makes and models without a cross reference table would be madness.........wouldn't you think??
The reason I ask is because I have C15A parts book that tells you all the part numbers of the transmission in Chevy/GM numbers, but on eBay that isn't always the case. Often I will find a gear that sounds correct in the description (size, number of teeth etc) but has a Perfection Gear Company or some other manufacture number. When they are asking, at times, some steep prices for these items, I can't bring myself to purchase the said items, especially if there is a no return policy as a lot of these sellers do have.
Any help would be appreciated

Hi Alan-

I don't know of a direct cross reference from Chev CMP numbers to GM but I do have a copy of the MapleLeaf GM parts book that gives all the civilian part numbers. Depending on the part you will find that the CMP part number is the same. Also some of the CMP parts books also list the Proprietary Numbers.

If you have particular parts you want the Mapleleaf numbers for let me know.

Now my Question are the MapleLeaf part numbers the same as the Holden part numbers. I've found that some MapleLeaf part numbers are different that the US General Motors Parts numbers.

Now as to transmission parts, I have found that GM civilian part transmission parts are interchangeable with CMP transmissions. So far I've used the civilian bearing numbers, top spline shaft that the shifting gears slide on.

Hope that helps a little.

Cheers Phil
