Hi all,

In my 2004 suburban, my tranny is gone/ or going out. When putting D or R....sometimes will move, most times not and when going down the road will slip out of gear.

Any change a fluid flush will resolve? Assume I need a new tranny.

Can I use pretty much any 4WD 4L60E or does it have to come from a 2004 truck or suv?

thanks!
