Hey everyone,
Just wanted to make a quick post to clear things up. In my older threads about my LJ71 3RZ-FE swap with the A343F auto, I shared a lot of info before I was 100% sure about it. I’m still learning, and I’ve realized some of that info wasn’t fully correct.
For months, the biggest...
Hey everyone,
I’m stuck and need some guidance:
• I’ve swapped a 3RZ-FE into my LJ71 and kept the original A343F trans + 2L-TE ECT ECU (PN 89530-60050).
• The TPS on the 3RZ-FE is plugged into the engine ECU, but the trans ECU never sees it.
• Without TPS input the...
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...

Thank you so much for sharing your experience — I really appreciate it!
My issue is a bit different though. The engine feels like it's struggling or under heavy load even at low speeds, like it's "out of breath" or being held back somehow. So it might not be just an idle control issue in my...
Thank you so much for the detailed reply, I really appreciate your help and the information you shared — it gave me a much clearer picture of how the system works.
After going through all this work, I’m actually starting to consider getting a 1998 Prado (J90) with the factory 6-cylinder engine...
Do you know where I can find the factory workshop manual or wiring diagram for the 70 Series in PDF format? I’ve been searching online but haven’t had much luck
Thank you very much for your kind and informative response — I really appreciate it.
Honestly, I wasn’t sure whether my transmission had a separate ECU or not. Your explanation helped me understand things much better, especially about the 4WD ECU and the vacuum system.
I’ll start checking the...
