general problems of the 2004 GMC Yukon

Trying to stop slowly and abs system move my Yukon to a point I almost hit the car in front of me. It happens when I try to stop under 10 miles per hour. Also 2wd drive drops to 4wd on highway and lose power. This is dangerous on the highway.

Tl-the contact owns a 2004 GMC Yukon denali. The contact stated that while driving approximately 60 mph, the vehicle stalled. After several attempts the vehicle restarted. The failure recurred numerous times intermittently. The vehicle was taken to a dealer for diagnostic testing. The mechanic replaced the tac module and electronic throttle body. The failure recurred. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 120,000. Ak.

As I slowed exiting a freeway about 35 mph, I heard a screech & a bit of loss of power. When I attempted to put into reverse for parking (later) it was apparent it was the transmission. As I investigated on line it was an ongoing transmission problem due to "less than robust parts" inside the transmission. Gm dealer-service rep. John at zubor agreed with this and told me to contact gm since it was, just over the 100,000 mile powertrain warranty. It took gm two weeks or more to reply & return my calls & emails, when of course I was told a gm dealer must diagnose the problem--vehicle was already repaired at that point by my own mechanic. I do not have another form of transportation & since it is out of warranty I had no promise of gm assistance, I took it where I could! I paid $1850. 00 for a new trans with warranty. I would not be writing except this is an ongoing problem & the gm tech on line said there was "nothing you could do to prevent this from happening since the interior parts are weak". Gm tech commented gm had began using more "robust parts for replacement, but due to high labor costs (interior parts) he suggested to replace trans so you would have a warranty". This is also what our mechanic advised. Please advise.
