NHTSA Complaint #10242906 — 2001 VOLVO V70XC

TRANSMISSION DISENGAGES AT LOW RPM (AT ABOUT 20MPH) WITH SLIGHT PRESSURE ON THE ACCELERATOR PEDAL - FEELS LIKE THE CAR WANTS TO UPSHIFT TO THE NEXT HIGHER GEAR (POSSIBLY 2ND GEAR), TRANSMISSION THEN DISENGAGES...THE ENGINE RPMS SURGE TO 3,000-4,000 AND THEN THE TRANSMISSION ENGAGES WITH A HUGE CLUNK AND SURGES FORWARD. WHEN COMING TO A STOP WITHOUT ANY GAS PEDAL PRESSURE, TRANSMISSION DOES NOT DISENGAGE, BUT SEEMS TO SHIFT INTO THE LOWEST GEAR AND SURGES FORWARD WHILE TRYING TO STOP THE CAR AT A TRAFFIC LIGHT OR STOP SIGN. AGAIN, THERE IS NO PRESSURE ON THE GAS, THE CAR AUTOMATICALLY DOWNSHIFT MAKING A LOUD CLUNK AND THEN THE ENGINE SURGES AND PULLS THE CAR FORWARD. AFTER A FEW SECONDS OF THE CAR TRYING TO PULL FORWARD WITH THE BRAKES APPLIED, THE TRANSMISSION DISENGAGES THE GEAR AND RETURNS TO A "NEUTRAL" SETTING WHILE THE CAR IS STOPPED. TRANSMISSION DISENGAGEMENT AND ENGINE SURGING ARE CONSISTENT WHETHER THE CAR IS HOT OR COLD AND THE PATTERN IS CONSISTENT - ALWAYS AT LOW RPMS WHEN THE CAR'S AUTOMATIC TRANSMISSION EITHER WANTS TO SHIFT UP OR DOWN IN GEARS. IT SEEMS LIKE THE ISSUE IS ALWAYS BETWEEN 1ST AND 2ND GEARS. AT HIGHWAY SPEEDS THE CAR SEEMS FINE. *TR
