My tranny broke this week and I need a new one asap. Looking to buy a level 5 4l60e or maybe a 4l80e. I know that most of you guys recommend an 80e but they rob a lot of power and it seems most people have pretty good luck out of the level 5s. PM if you have any suggestions. Need to get my truck rolling again because I need my truck to pay the bills. Thanks guys.
