ah yup, that's gonna be way more of a PITA. I'll try to find one with the transmission for sure. thank you!Yes and no, the 80 a343f uses a TV cable for line pressure, and the newer a343f used with the 2UZ controls pressure electronically via the ECU and has an additional sensor. It is possible to retrofit, just more work. You would also need to swap valve bodies from a donor tundra/Sequoia etc. It's just a lot easier to use the 100 trans the way it is, if you can find one. Check This thread for some more info on using the 80 trans.
