What is a sun shell in a transmission?

The vehicle sun shell, also known as the reaction drive shell happens to be the weakest link in all 700R4/4L60E models.

It is made of a thicker steel which happens to be 10x stronger than all OE shell

I have been able to use this shell in all my rebuilding, and have never seen any one of them failing. And this also includes a new plastic thrust washer.

So what does a sun shell do in a transmission?

Mostly, the sun shell avoids the weight that it finds in traditional, or heavy-duty aftermarket shells, this is because there is a unique combination of an improved looks and the production for a maximum strength shell which is only slightly bulkier than OE. 

However, to avoid thrust loads from overweighting the captured planetary bearing, your sun shell features a bigger bearing and custom roller clutch race. The components re-route some thrust loads via the carrier, perfectly bypassing the softer bearing;

1. Stopping spline stripping
2. Avoiding hub breakage
3. Terminate the planetary bearing failure

4. You will have a clean break without lots of metal shavings or filings
5. You will hear a big clunk sound

These are the symptoms you would likely observe, but in case these symptoms aren’t what you are seeing, then it means your sun shell is not yet bad. Normally, the 1st and 3rd gears will still be working well. Whenever your sun shell fails completely, you will normally observe a clean break without lots of metal filings or shavings.
