Use an OBD-II scanner to check for "P" codes (e.g., a TCC code). These will tell you if the computer has detected specific gear ratio errors or sensor failures. Common Solutions
If the transmission shifts but fails to "lock up" in higher gears, it can generate immense heat very quickly, eventually leading to smoke. This is often an electrical issue involving solenoids or valves.
Assuming you are referring to automotive issues with a (often colloquially called a "tranny") that is overheating ("hot") and emitting smoke , this is a serious mechanical problem that requires immediate attention to prevent total failure.

Once the engine has cooled slightly, check the dipstick (if your vehicle has one). Low Fluid : Can cause friction and overheating.
: The most common first step if the fluid is burnt. Use an OBD-II scanner to check for "P" codes (e
: If the fluid is black or smells burnt rather than bright pink/red, it has lost its lubricating properties and must be replaced. Expert mechanics at JustAnswer note that smoking often occurs after a short period of operation if fluids are severely degraded or leaking.
: If the smoke is caused by fluid hitting the exhaust, replacing the leaking seal is mandatory. This is often an electrical issue involving solenoids
If you see smoke coming from your vehicle or smell a burning odor (often like burnt toast), follow these steps:
