Hello All,
I purchased a 2006 Chevrolet Silverado 4x4 this summer with the 5.3 liter V8. The RPO codes show that I have an M30 transmission. This truck being a Z71 is a 1500 series light duty truck. What automatic transmission does this truck have? I assume it's related to the 4L60-E that my 99' Silverado had.
Also what I'm really writing about is does this transmission have a lock up converter? My old truck I could feel the transmission shift four times and then feel the converter lock, causing the RPM's to drop a little. My new truck I can feel the transmission shift four times but don't feel the converter lock. Does this truck have a lock up converter?
Thanks, Brian
