Buyer's checklist

What to check before buying a used transmission control module

  • Match OEM hardware and software part numbers exactly, as shift schedules and solenoid driving algorithms differ between gear ratios and engine sizes.
  • Determine if the module is standalone, integrated into the PCM/ECM, or mounted internally on the transmission valve body (mechatronic unit).
  • Check if the module requires VIN programming, clutch adaptation relearns, or flash updating before normal gear engagement will occur.
  • Inspect connector pins for fluid wicking; leaky transmission harness seals can force transmission fluid up into the TCM connector plug pins.
