Code P0976 Acura Description

When shift solenoid valves A, B, C, D, and E are turned ON, the hydraulic pressure circuit opens. The hydraulic pressure circuit supplies/discharges hydraulic pressure to/from each clutch according to the combination of the ON/OFF status of the shift solenoid valves. The Powertrain Control Module (PCM) commands the driver circuit to turn on the shift solenoid valve. The circuit diagnoses malfunctions such as a circuit short or open, and sends back a return signal during the PCM's command. When the return signal does not match the PCM command, a malfunction is detected by the PCM. When the return signal does not match the PCM command to turn ON the shift solenoid valve, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).

If the light is flashing, it means that there is a problem with the transmission. The next step is to check the transmission for codes. If you got the P0976 code, then you may have a problem with the Shift Solenoid Valve 'B'. Before replacing any parts make sure the transmission fluid level and condition is OK. Change the fluid if necessary.

P1148 and p0325. What would be the first step? Change both front 02 sensors correct? Will I need to also change the single downstream sensor?

For the P1148 code I'll start by cleaning the MAF and changing the air filter. For the P0325 you more than likely have to replace the knock sensor.
Also, before replacing any parts, try using high octane gas and if possible a fuel additive.
