Is it Possible to Swap 4-Speed Automatic Transmission for 5-Speed in Toyota Belta?

I have a Toyota Belta with a 2NZ FE engine and a 4-speed automatic transmission. Its an AWD model. I want to swap the gearbox for a 5-speed automatic to reduce engine revs, lower noise, and improve fuel economy. Is this possible? And would it be a simple swap, o r would I need to replace any electrical parts too?

Yes, swapping to a 5-speed automatic is possible, but it may not be a straightforward bolt-on swap. You’ll likely need to modify o r replace electrical components like the ECU and wiring to ensure compatibility with the new transmission. It’s best to consult a mechanic experienced in such conversions for proper guidance.
