How to I.D. SM 465 tranny

I have a granny low 4 speed transmision out of a 1975 Suburban mated to a 205 transfercase. I'm assuming this is a SM465. How can I be for sure?

The numbers I found on the top shifter plate:

GM21
8901181
D285
The numbers I found on the trans. case:

11
GM
0175
6273212

This was all I could find. The next big question is what gear ratio does this transmission have?

As always thanks for all replys!!!

Re: How to I.D. SM 465 tranny

if its a 465 they are like 7.02:1 first, and even a biut lower for reverse.

I think the 420 and 465 were the main GM light/med granny 4 speeds, and I think the 420 was phased out in teh 60s.

but not sure, not quite my cup of tea, so I could be way off base, there should be photos and tech info on the orc website, you can look up there to figure out

Someone posted this link a few days ago where they adapt an AMC bellhousing to the 465. They have another page showing the different versions of the 465, but I don't think they have the tag numbers, but have a look anyway.

You have an SM465. It was the only 4 speed used in the light/medium duty vehicles, and was very common. It has a 6.55:1 first, and is nearly bulletproof. I swapped one into my Scrambler from a '72 dump truck.

I recently acquired the same combo myself. Can't wait to install it along will a 10 bolt front and 14 bolt rear. I'll check the numbers on mine and post them here in the next few days. I would do it sooner but the tranny is at the shop I work at.
