Transmission or Brake Binding Issue Preventing Movement
The vehicle is in gear but won't move when the engine is cold. This could be due to a stuck brake caliper, a frozen parking brake cable, or a transmission issue such as low fluid or a faulty shift solenoid. The cold condition suggests possible moisture-related freezing or fluid viscosity problems.
Diagnosis Details
Possible Causes
Frozen or seized brake caliper or parking brake cable due to moisture or corrosion, causing the brakes to drag and prevent movement when cold.
Low or contaminated automatic transmission fluid, leading to insufficient hydraulic pressure when cold.
Faulty transmission shift solenoid or valve body issue causing delayed engagement in cold temperatures.

What You Should Do
Check if the vehicle rolls freely in neutral with the engine off (safely on level ground).
If not, inspect brake calipers and parking brake cables for binding.
If it rolls freely, check transmission fluid level and condition when warm; look for diagnostic trouble codes with a scan tool.
Consider having a professional diagnose transmission engagement issues.
