Dana 20 question

[14Justice]

I'm going to be using my stock Dana 20 I separated from my 3 speed. When I pulled them apart I started thinking about the need for marry it to my 4R70W. I know I need the Advance Adaptor kit and I'm picking that up while I'm in Oregon. When I look at the photos of the kit, it confuses me that there is no gear set that was still attached to the output on 3 speed. There is a void in the transfer case. The photos of the A.A. kit doesn't show any gear set with the kit. Is there something else I need? Is there a Dana 20 input set made especially for an auto? Or did I seperate the two wrong? Thanks in advance for the help... Brad

There is a spud shaft that runs between the trans and xfer case inside the adapter. No gears or what not, now as for output splines on a 4r70 vs 3spd I don't know but if a new one was needed than AA would include it in there kit.

When you split the D20 from your 3-speed you need to pull the snap ring and D20 input gear off the 3 speed tailshaft. This gear will go on the new spud shaft that comes with the kit before bolting up the D20.

Thank you, I'm sure that's what I didn't do!

I was working on the build today and looked at the output shaft and couldn't see the snap ring. Where would that thing be? Like an idiot, I didn't take a photo...
