4L70E in CHAMPIONSHIP EDITION
Does anyone out there know if the the GM 4L70E part # 19260961 is compatible with the 2009 H3 5.3 Transmission control module. My research tells me that other than a pan swap, everything is identical mechanically, just conflicting information regarding "programming". Any input would be appreciated!- Ordieh
