2010 Nissan Pathfinder Transmission Problems

While driving at 35 mph through a busy intersection, your car suddenly shuddered, all dashboard lights came on, and the engine shut down completely—leaving you without power steering or brakes. You were able to coast to safety, but this loss of control in heavy traffic created a serious hazard. The dealer diagnosed failed camshaft sensors and a faulty crankshaft sensor as the cause, and replaced all three components.

Coolant leaked from your radiator into your transmission, causing the transmission to fail. This required replacing both the radiator and transmission at a cost of $6,000. The manufacturer has not acknowledged this as a known issue.

Your radiator developed an internal leak that allowed transmission fluid and coolant to mix together, contaminating both systems. Your vehicle suddenly lost power and stalled while driving on the highway at 50 mph, with no prior warning signs despite regular maintenance. The transmission and radiator were replaced at a dealership for $5,086, but the owner is concerned the same defect may recur. Fixing this issue will require radiator replacement and transmission service or replacement to address the fluid contamination.

Your radiator developed a leak that went unnoticed for some time, allowing coolant to mix with your automatic transmission fluid and contaminate it. Even after replacing the radiator and flushing all fluids, the transmission has been damaged beyond repair. You'll likely need a complete transmission replacement or rebuild to restore your vehicle to working condition.

After you drained and replaced your coolant and radiator fluid due to a milky fluid leak, your car now revs at high RPMs before shifting into gear when you press the gas pedal, especially after backing up. This delay in shifting creates a safety concern because your car takes longer to accelerate, putting you at risk if another vehicle is approaching. The transmission may need inspection or servicing to resolve the shifting delay.

Your engine coolant (antifreeze) is mixing with your transmission fluid, causing a yellow milky sludge to build up in the radiator while your transmission fluid runs dry. This happens when the radiator develops an internal leak that allows coolant to seep into the transmission system. The fix will likely involve replacing the radiator and flushing both the cooling and transmission systems.

"TAKATA RECALL"; WHILE DRIVING ON THE CITY STREETS IN LOS ANGELES, CA THE POWER TRAIN (AUTOMATIC TRANSMISSION) FAILED AND THE RADIATOR FAILED. THE GASKET IN THE RADIATOR THAT SEPARATES THE OIL AND WATER FAILED IN THE RADIATOR WHILE THESE FLUIDS ARE COOLED WHEN THE VEHICLE IS RUNNING. ONCE THIS GASKET FAILED, THE WATER AND OIL MIXED TOGETHER. SENDING WATER MIXED WITH OIL INTO THE TRANSMISSION. THE WATER IN THE TRANSMISSION RUINS THE TRANSMISSION VALUE BODY, ELECTRICAL PARTS & GEARS ALSO OVER HEATS THE VEHICLE ENGINE. THE TRANSMISSION NEEDS TO BE REPLACE, THE RADIATOR NEEDS TO BE REPLACE, FLUSH OF COOLANT SYSTEM, FLUSH OF TRANSMISSION AND REPLACE ALL FLUIDS (TRANSMISSION OIL & COOLANT FLUID). I REPLACEMENT OF TRANSMISSION OR REBUILD. I HAD THE TRANSMISSION REPAIRED AT A COST $3000.00 PLUS A RADIATOR AND FLUIDS/OIL AT A COST $500.00 FOR TOTAL $3500.00.

I BOUGHT THIS VEHICLE NEW IN 2010. WE ARE A VERY TYPICAL USERS WITH A FAMILY OF FOUR (CURRENTLY WITH ABOUT 120K MILES). I'VE HAD REGULAR PROBLEMS (SERVICE ENGINE LIGHT WOULD TURN ON). STARTED WITH SPARK PLUG REPLACEMENT A FEW TIMES, ENGINE CONTROL MODULE REPLACEMENT, AND NOW LATEST ENGINE REPLACEMENT. I'VE ALREADY SPENT MORE THAN $6K OVER THE LAST FEW YEARS ON THESE ISSUES. THE DEALER IS NOW QUOTING $12K FOR REPLACING THE ENGINE. I SIMPLY CANNOT AFFORD THIS. PLEASE LET ME KNOW RIGHT AWAY WHAT OPTIONS I CAN PURSUE (INCLUDING A LEMON LAWYER, ETC.).

TRANSMISSION FLUID MIXED INTO RADIATOR. VEHICLE STALLS, OVERHEATS, VIBRATES, TRANSMISSION DOES NOT FUNCTION RIGHT. VEHICLE WAS DRIVEN ON CITY STREET.
