Description
Heavy towing and stop-and-go use can put extra thermal load on a truck automatic transmission. Mishimoto MMTC-GMT-99 replaces the smaller factory cooling arrangement with a larger stacked-plate cooler for specified GM pickups.
Its quick-disconnect hardware works with the compatible factory lines, while the -6ORB ports offer an alternate path for custom plumbing. This kit must not be selected for trucks equipped with an Allison transmission.
