This is a quick follow-up to my last post about swapping a 3RZ-FE into my Prado LJ71 (originally 2L-TE with A343F auto trans).
I’m still stuck. I used a manual 3RZ ECU and didn’t replace the transmission ECU. The car runs, but shifts feel off, torque is weak, and I don’t know what’s wrong exactly.
Biggest confusion now: is my A343F (from the old diesel setup) the same as the A343F used in petrol 3RZ/5VZ trucks? Do they have different valve bodies or electronics? No clear answers yet.
I’m still learning as I go. Any help from someone who’s done this before would mean a lot
