To those who helped with the engine mating process, thank you. I pulled the transmission out and reattached it that way and the whole assembly is now back in the truck. I have looked around on the internet to how people have installed the dipstick tubes with no solution to the 20Rs or 22Rs. Some Chevy engines have o-rings on them but the Toyota ones seem to just “slip” in. Should I use RTV or some kind of sealant to reinstall?
