Hi,
ECU in my 1992 Patrol TB42E with 4 gear automatic transmission is not working properly.
The current ECU is 23710-34J10 MECM-P740 AG.
I found a used one 23710-34J05 MECM-P710 AE.
I heard that J10 may mean automatic transmission?
and what about J05?
P740 and P710, I suppose that it may describe the software version in ECU ?
After reading different posts, I'm still not sure if there is any difference between ECU for manual and automatic as there is a separate TCU for auto transmission.
What do you think?
Do you think that these ECUs are interchangeable?
Best regards,
Marcin
