OEM computers?

Can anyone tell me what the ECT unit is for? Is it the transmission computer or traction control?

Electronic Controlled Transmission.


Traction Control is TRC.

also, on newer models they may have what is called ECT-i which is merely "Electronic Controlled Transmission with Intelligence" and on my car, TRAC would be Traction Control though I'm not sure what the A would mean.

The ECT button changes the shift schedule. The throttle cable to the trans merely raises line pressure, and the TPS and speed sensor determine shift timing. On a standard hydraulic unit, the throttle cable would raise, delaying an upshift until governor pressure overcame it, and forced an upshift.
