Your going to have fun with this lol!! Youll also need the driveshaft out of the manual truck too cause the automatic tranny is longer then the manual & the automatic shaft wont work!! Oh & try the computer thats already in your truck too before you swap it because I didnt have to swap my computer when I did the conversion!! Oh & not sure how many miles are on your truck, but another good thing to do while the tranny is out & you have access to it is too replace the rear main seal!! Other than that you seem to be heading down the right path! Hit me up if you have anymore questions!
*Here is a pic of what TAP-Toyota Auto Parts sent me when I told them I was doing the manual conversion!
