Just an update... received my complete refund on Monday, down payment, payments, payed off my loan. When I went to the dealer to sign all the papers, they now had the cab removed to reassess the fix that did not help. The first time they removed the front end, motor etc to add the shim and the new reluctor wheel; but then the truck would not start at all--it would just turn over. The GM engineer had them remove the cab to figure out what happened--so basically the whole truck has been tore apart--sure glad I am out of that rascal.
