Allison At545


New Member
Hey Allisonman I have A chevy C6500 tow truck with a At545 transmission. While driving down the road at 55 mph I lost everything. It was like in jus went in Nutral. Earlier that day I had an electronic break system put on it so that I could tow a trailer and have trailer breaks. Do you think that did something or could it be something else . The pto also does not work now and it is mounted on the side of the tranny. Is there some type of electical shut off? It does not move in any gear 1St 2nd 3rd drive or reverse. It is an automatic and the year of the truck is a 2000. All the linkage seems to be hooked up. Any help would be great thanks
