Genuine Allison Spin-on Transmission Filter #29539579

You chose Allison Automatics to get the most performance, reliability, and productivity from your Sierra or Silverado HD pickup truck. So, when it comes to their care and maintenance, protect them using Genuine Allison Filters. Allison maintenance schedules are specific to Allison genuine filters, so don't risk using the aftermarket or look-a-likes, which may not filter the same size debris nor have the same debris holding capacity. Compare our prices to your GM dealer, and tell your friends! Don't forget to save your magnet from your old filter, clean, and reuse on your new one.
