Frequently Asked Questions

Is delayed engagement dangerous?

Not immediately, but a delay before Drive or Reverse can end in a sudden lurch and usually signals growing wear.

It only happens when cold. Does that matter?

Cold-only delays often mean worn seals and low pressure. It typically gets worse with time.
