I have a 5R55S with a Trick Flow deep pan and dipstick for sale. Trans has 60K miles on it. The pan adds 2 more quarts of fluid to it. I also have a 4" Axle Exchange 1 piece driveshaft for sale . You will need the coupler / adapter for the rear end as I used it for my swap.

Asking $600 for the trans / pan
Asking $500 for the driveshaft
Asking $1000 for both of them.
