No issues are rated critical, indicating generally reliable ownership. Across all issues, repair costs range from $30 to $1,500. DIY maintenance guides at au7o.io.
On the 1991-1998 Volvo 940, the AW30-43 automatic transmission develops overdrive lockout, harsh shifts, and eventually complete failure. The solenoid and valve body are common failure points.
Begin by confirming fluid condition and level, then scan/inspect the overdrive electrical circuit, shifter switch, relay, wiring, and the AW30-43 overdrive solenoid for proper power and resistance. If overdrive is inoperative or the 2-3 shift is harsh, remove the transmission pan and inspect for debris, then service or replace the solenoid and clean/rebuild the valve body, as sticking valves and worn bores are common causes; fresh Dexron-spec ATF and a new filter/screen should be installed at the same time. If slipping, delayed engagement, or heavy clutch material is present in the pan, the unit usually needs a full rebuild or replacement transmission rather than solenoid-only repair. Typical costs are about $150-$400 for diagnosis/fluid service, $300-$800 for solenoid/valve body repair, and $1,800-$3,000 for a complete rebuild.

On the 1991-1998 Volvo 940, the PCV flame trap (crankcase ventilation system) clogs with oil sludge, pressurizing the crankcase and causing oil leaks from every gasket and seal. This is the number one maintenance item on all redblock Volvos.
Inspect the crankcase ventilation system by removing the flame trap, breather hoses, and oil separator/breather box under the intake manifold; if the flame trap is restricted or the hoses are soft and sludged, the system is overdue for service. Clean or replace the flame trap, all PCV hoses, and ideally the breather box and intake manifold gasket, then verify crankcase vacuum at the oil filler cap or dipstick tube at idle to confirm proper flow. If the engine has been leaking for a while, also inspect and replace pushed-out cam, front crank, or intermediate shaft seals as needed after restoring ventilation. Parts typically run about $50-$150 for a basic flame trap/hoses service or $150-$300 with breather box and gaskets, while shop repair is commonly $300-$700 depending on access and how many seals are already leaking.
