Understanding your Automatic

Garage shifts

While selecting gears first thing after starting the engine, take note of the engagement time between moving the selector lever and feeling the engagement. There can be a longer delay in reverse, when compared to drive (due to the extra internal components applied and the higher oil pressure required).

An engagement time of more than 2 seconds should be checked out by a technician.

Variation in shift feel

Shifts feel different from transmission to transmission even within the same brand of vehicle. Soft and firm shifts can be acceptable and considered somewhat normal.

Flare

Watch out for a “flare” which is a partial neutral between one ratio to the next as the transmission shifts. A flare shows up as a momentary rise in engine rpm during the shift and will accelerate clutch wear if ignored and can lead to early transmission failure.

Testimonial

"Hello, I just wanted to thank you for such great service. My car, Audi A4, was serviced by your team. We were unsure of what could be wrong with the vehicle but it is running so much more smoothly and we are very happy. Reluctantly, we will now sell it to our son, but with it running so well, would prefer to keep it. You may recall me talking about this."

Regards,
Margaret Fowler
