960 Transmission shift prob, blinking up arrow, code P0500

Having A 960 Transmission shift prob?

Just bought a used 1996 960 and it’s started having a transmission shift problem. Sometimes when I drive, the transmission suddenly changes gears, usually downshifting, and seems to have a hard time staying in high gear (overdrive) with steady (slight) throttle.

I get blinking UP arrow on dash, the blinking W S E lights, and Check Engine light. The code reader at Autozone gives code P0500 Speed Sensor.

From what I can tell by searching the forums, the P0500 is many times treated as an ABS problem, but in my case, I don’t have ABS light and my ABS works. Other threads seem to indicate P0500 is PNP switch on gear selector. But I don’t have any problems getting the shifter out of Park and it seems to select lower gears (3 L) just fine.

Bonus! More on the Volvo 960

Autumn 1990 saw the launch of the Volvo 960, in time for the 1991 model year. The new Volvo 960 replaced the outgoing Volvo 760, which had been on the market since 1982.

The Volvo 960 was powered by an all-new in-line 6-cylinder engine, with a displacement of 3 litres. It was an advanced power unit featuring an aluminium cylinder block and double overhead camshafts allied to 4 valves per cylinder. This engine represented the first stage in an entirely new generation of in-line engines, which eventually extended into the creation of a new series of 5-cylinder and 4-cylinder Volvo engines.

For the Volvo 960 a number of new safety features was also unveiled, among them a three-point inertia reel seatbelt and an adjustable head restraint for the middle of the rear seat. Further enhancing the new car’s safety profile, an integrated child seat built into the rear seat’s middle armrest could be specified as an optional extra.

These and other safety developments gained the model considerable international accolade, not least among them the “Prince Michael Road Safety Award” and the “Autocar & Motor” prize for the best safety features.

For model year 1995, the Volvo 960 underwent a comprehensive redesign. The front was given a new appearance; the chassis was almost totally new, including a further developed version of the multi-link rear suspension with a transversely mounted leaf spring of composite material. A new 2.5 litre version of the 6-cylinder engine supplemented the previous 3-litre version.

In 1997, the Volvo S90 replaced the 960 Sedan.
