GMC 4L60E, 4L65E, 4L70E Valve Body 2003-2008, Sonnax Updates, Dyno-Tested

Costs are just too high to make that realistic. Granted a used part may last you 100,000 miles depending on it’s previous use, or it may last you a month, you just don’t know. This valve body is better than OEM, it features many Sonnax upgrades to increase reliability over the standard OEM valve body.
