GM WONT REPAIR MY TRANSMISSION

[Hummertech]

One other piece of advice for when you have your trans rebuilt. If they replace your 2-4 servo(which is what actuates your 2-4 band) with a Corvette servo, you'll get a much firmer more positive shift. That would help make the band more durable. The only downside is a firmer shift when just cruising around town, but your trans will hold up better. Remember, when your trans is actually shifting, things are slipping, and that is bad for the trans. The faster and harder you can make it shift, the easier it is on the trans.
