Difference between MT and AT calibrations

Post by thunderbt3 »

Just curious, what are the differences between MT and AT calibrations? Could a MT calibration be applied to an AT vehicle? If so, what items need to be checked or updated for applying to the vehicle?

From the website:

07-08 MT swap ECUs are hard to find for my 04-06 MT TSX. Can I use an AT ECU?
Yes. FlashPro Manager 1.7.2 or newer allows a MT calibration to be written into an AT ECU.

What AT ECU part number is supported?
37820-RBB-A71

Will the AT ECU work the same as the MT ECU?
No. Reverse lockout does not work in an MT TSX using an AT ECU. This means you will need to be more careful on 4-5 and 5-6 gearshifts as you can inadvertently move the gearshift into the reverse plane.

Can I drive my MT 04-06 TSX with the AT ECU before programming it with the FlashPro?
Yes after the immobilizer has been synchronized. It is not recommended though. There will be error codes as the ECU is looking for an AT transmission. Shifting will not work well as the AT shift logic also affects the drive by wire.
