Does the transmission hard shift into 2nd under heavy acceleration?
How's the fuel economy?
I'm thinking MAF.
The ECU and TCU work together to give smooth shifts.
The MAF is vital to the ECU for this as it gives information on engine load and torque based on throttle position and airflow.
When my MAF went I got a very bad shift 1st to 2nd under heavy acceleration.
