Technical Service Bulletin


Some 2019 Ranger vehicles may exhibit a vehicle buck/surge during low-speed operation and/or an engine that runs rough after cold start. This may be due to various software parameters within the powertrain control module (PCM). To correct the condition, follow the Service Procedure to reprogram the PCM.


Follow the Service Procedure steps to correct the condition if the vehicle meets all of the following criteria:

  • 2019 Ford Ranger
  • Vehicle buck/surge during low-speed operation and/or an engine that runs rough after cold start

Eligible under provisions of New Vehicle Limited Warranty (NVLW)/Service Part Warranty (SPW)/Special Service Part (SSP)/Extended Service Plan (ESP) coverage.

NOTE: Advise the customer that this vehicle is equipped with an adaptive transmission shift strategy which allows the vehicle’s computer to learn the transmission’s unique parameters and improve shift quality. When the adaptive strategy is reset, the computer will begin a relearning process. This relearning process may result in firmer than normal upshifts and downshifts for several days.
