Shift solenoids for 6l80e in '04 Denali.

[AR2007denali]

Is there a cheaper place to order the shift solenoids than going through the dealer? Does anyone out there make an upgraded solenoid? Any info would be appreciated.

Did you swap a 6L80 in? I thought the 04s had a 4L65 or something. GMHTP has a good article about how Circle D builds up their 6L80Es to handle more power
