Delayed Drive or Reverse engagement
A noticeable delay after selecting Drive or Reverse may relate to fluid pressure, control systems, wear or adaptation issues.
Jerking, slipping or unexpected gear changes
Harsh shifts, engine revving without matching acceleration or unexpected downshifts require scan data and mechanical checks.
Warning lights, overheating or fluid leaks
Transmission warnings and leaks should be inspected quickly because low or degraded fluid can contribute to serious damage.
Diagnosis before repair
A proper process may include fault-code scanning, live data, fluid condition, leak checks, adaptation values and a controlled road test.
