I had this same problem and it had nothing to do with the fan but the transmission. The dealership did some computer upgrade and fixed the problem The older model years should have had a PCM re-flash from the dealer. If this problem re-occurs after the fan-clutch is replaced then a reflash is needed. There are many cases where the reflash is the only correstion needed and the dealer is the only place it can be done unless you know a PCM tuner shop.
