Had problem with TIPM 2011 GC. Dealer price $1300. Replaced myself for $325.00 . It took me 30mins.
Good for you. Stick around, read and post. Losts of Pros and DIYer’s here. Welcome!
Is that a complaint or a brag:grin:
Did you install a brand new factory tipm . . . or a rebuilt or used unit?
I’m not entirely certain, but I believe the tipm needs to be programmed and set up after installation
