Ok i have a 700r4 in a 92 chevy 4x4. I have put in a corvette intermediate servo, a overdrive super servo. an 3 quart oversize pan. A temp. gauge. I also put on a torque convertor lock up switch. It also has a tranny cooler on it. My problem is when i tow in overdrive i'm loseing some tranny fluid somewhere. It is coming from around the front of the tranny. I believe from the vent hole. It is not getting hot. I towed my boat over 300 miles this weekend and it never got over 125 degrees unless i was sitting at a stop light then it would go up to 150 and back down when i started going again. The truck has plenty of power and pulls just fine. The only problem is the mess it makes. I know alot say you shouldn't pull in overdrive, but it has also been said it is ok if your torque convertor isn't going in and out and your tranny isn't getting hot. Plus i added the overdrive servo which is suppose to be for towing. What could be wrong to be causeing this mess? I always thought it was getting hot but the gauge says different. The sensor is in the pan btw. thanks in advance for your replys.
