Is it common for the front seal to give up on heavy hauls? After arriving home from pulling my 32' travel trailer on a 350 mile highway trip I noticed a trail of fluid in the driveway. The leak appears to be coming out of the front of the transmission. I checked the fluid level and it was down just alittle so I don't think it had been leaking for to long. The trans temp never rose and the fluid is not burnt so I am thinking no damage to the unit???
