Vortec MAX Posted October 31, 2007 Report Share Posted October 31, 2007 AWD is the 4L65E. 2005-06 2WD is the 4L70E. This is my understanding as well. And, the 4L70E comes with a 14 bolt semi-float rear axle in the Silverados. Mike Quote Link to comment Share on other sites More sharing options...

Rausche Posted October 31, 2007 Report Share Posted October 31, 2007 Wow I always would've assumed that I had an RPO M30... I'm pumped to find out that it's actually a 4L65 (even if they're nearly identical transmissions!!) Sorry to thread jack, but does anyone know if the SS ever came with the RPO G80?

Fireman31 Posted October 31, 2007 Report Share Posted October 31, 2007 (edited) I thought that I had a 4L70e being RWD, but I have the RPO M32 in the glove box, which means a 4L60e according to the GM Truck website??????
