Transmission or Brake Binding Issue on Cold Start
The vehicle is in gear but won't move when the engine is cold. This could indicate a transmission problem (e.g., low fluid, valve body issue) or a brake system binding (e.g., frozen caliper, seized parking brake). The cold condition points to fluid viscosity or component contraction as a factor.
Diagnosis Details
Possible Causes
Low or contaminated automatic transmission fluid (ATF) causing delayed engagement when cold
Seized brake caliper or frozen parking brake cable holding the wheel(s) when cold
Transmission valve body or solenoid issue due to cold fluid viscosity
