Does your speedometer and tach still work when the CEL is on? You need a better mechanic or one with a better diagnostic tool. Usually when the flashing arrow happens AND the CEL is on, the tranny found a fault and signaled the ECM to turn the CEL on because it is severe. Not just a throttle position sensor.

The MAF, air flow sensor, could promt this or the PNP switch could be faulty and not supplying the vehicle speed to the TCU.
