Its a toss up. If your motor is stock--sometimes they last 200k miles, sometimes they last 20k miles. But if you start throwing decent power at it (330+rwhp), they tend to loose the 3-4 clutch pack quickly and the bands wear. I would not be scared with a 65e, HD-2, and servos. If that tranny can;t hold the power--its obvious you need to step up and have a 65 built to LVL 5 specs. If you blow that--time for an 80e!
