Default NIce set of pictures Keith....

Tranny picture reminds me of the Chev tranny I removed while the engine was suspended from the bucket of the tractor.....made it easy forme to reach underneath and remove the two largebolts that holds the tranney to the bellhousing and can only be reached form the underside.

Never occurred to me to check for any liquids inside..... first bolt came off and at least 2 liters of clear water poured out..... not to concerned to get out of the way its only water..... but all the tranny black thick oil was floating above it......... needless to say I was well lubed.

Even with all that water inside the tranny it seems a lresidual light coating of the black tranny fluid remained on the shafts and bearing and all was salvageable after years of soaking...... they sure build them well in those days.

What is the tranny called? I have a 420 and it isn't the same as that.

I don't know of the CMP Chev transmission having a name, it was simply the 4 speed truck transmission.
For a while I was looking at trying to find a SM420 to put into my C15A. In the end I decided it wasn't worth the effort. Although the SM420 is compact by today's standards it is still quite a significant bit larger than the CMP transmission. Putting one in would mean either shortening the already short driveshaft between transmission and transfer case or moving the transfer case and as a result the mounting crossmember and shortening the rear driveshaft. Life would be simpler for someone with a 2 wheel drive CMP, only one driveshaft to shorten.
