NHTSA — Power Train: Automatic Transmission: Control Module (Tcm, Pcm) Problems

CarComplaints.com Seal Of This Might Hurt

CarComplaints.com Notes: The 1999-2003 Acura TL has a known & widespread defect with the transmission.

Honda fixed some vehicles with a recall in 2004 by changing the oil cooler return line. To settle a class action lawsuit in 2006, Honda extended the transmission warranty on some of these Acura TL's to 93 months / 109,000 miles.

Now these vehicles are past the warranty limit, so buyer beware.

problem #2

TL 6-cyl

  • Automatic transmission
  • 81,400 miles


Transmission began to slip during normal driving, I then researched this problem on the internet and learned that this was not an isolated incident and I became concerned for my family's safety due to descriptions of other peoples history with this car. I took car to dealer and they determined that a replacement was warranted. PCM unit was also replaced. They replaced transmission with a re-manufactured unit, old part is not available.

The PCM control module malfunctioned, causing transmission to down shift at random times. Shifts while pressing the accelerator, and without warning the steering wheel locked up.
