How much HP can a stock 68RFE handle?
500rwhp

Why does the 68RFE fail?
The most common failure point of the 68RFE is the Overdrive clutches. The OD clutch assembly from OE has significant weak points, even at stock power levels. Add increased engine power, larger tires or a heavy load, and there is a very high probability this will be the first failure of the 68RFE.
