We recently had a 2002 Ford Explorer come into our shop with a shifting complaint. The customer had noticed that it slipped or felt bumpy when under a fairly hard acceleration.
Our initial inspection consists of a road test to verify customer concern, computer scan for trouble codes and a visual inspection. On the road test, I felt what the customer was describing; it actually felt kind of like an abrupt engine misfire, something like you would feel with a manual transmission car or a misfire when TCC was applied.
