Where is the TCM located on my 2006-2009 Pontiac Montana?
On the Pontiac Montana, the Transmission Control Module is typically located on the LH (driver’s side) strut tower in the engine compartment. Always disconnect the battery before beginning the replacement.
Will this part fix a P0700 trouble code?

Ignoring a failing TCM can lead to progressively worse shifting, poor fuel economy, and eventually, could cause internal damage to your transmission from the constant harsh engagement. It can also leave you stranded if the vehicle gets stuck in limp mode.
