The smell of burnt oil in an automatic transmission may indicate the following problems:
Mechanical faults:
* Wear of friction discs, metal parts or bearings
* Damage to the housing or internal components of the transmission
* Torque converter malfunction (if equipped)
Fluid problems:
* Fluid overheating due to low level or poor cooling
* Fluid contamination and debris accumulation
* Using the wrong type of transmission fluid
Electronic problems:
* Malfunction of solenoids responsible for gear shifting
* Problems with the transmission electronic control unit (ECU)
What to do if you notice the smell of burning oil:
* Stop the vehicle: Immediately stop the vehicle and place the transmission in Park (P) mode.
* Check fluid level: Check the transmission fluid level using the dipstick and add fluid if necessary.
* Check the color of the fluid: If the fluid is dark or burnt in color, it may indicate contamination or overheating.
* Contact a specialist: Do not continue driving with the smell of burnt oil. It is necessary to contact a transmission repair specialist as soon as possible for diagnosis and repair.
Until the source of the odor is identified and corrected, driving the vehicle may cause further damage to the transmission and even cause it to fail.
