Volvo P2 R 90k Service Item Checklist

Volvo P2 R 90k Service Item Checklist -

I bought a 2004 V70 R in 2010, and I needed to “baseline” it, get it back to Stage 0. I wanted it to drive like it came right out of the Ghent, Belgium factory like it did in July 2003. After the 90k service listed below, I gave her some Seafoam and new tires.

Troubleshooting 2001 and 2002 Auto Transmissions

Neutral control bump is the result of the pulsed solenoids getting bore wear and the pulsed signal outputted by TCM is not really getting the pressure regulation desired. There is no pressure sensor so the TCM infers pressure through its adaptive shift control, i.e., if the shift is completed within the target time with X% solenoid signal then .5X% should be the right signal to reduce clutch apply pressure to let it slip during N control and not have slam engagement when brake is released. With worn solenoid or valve body spool valve bores the pressure with that reduced signal is not what is inferred via software.
