I've read this form and searched, but I am still confused a little. Supposedly TM came out in 99, but was available in 93 with the 4l60e. So does my 96 Vortec 350 with the 4l60e with push button 4x4 have this TM crap? I know at times I wonder why my truck dogs for a second and then fires up like a beast awakened from a slumber under heavy throttle to accelerate.
