Regarding my previous post, I appreciate everyone's comments. Had my burned oil changed this morning, drove about 10 miles so as I could get an accurate reading when hot, trans still works fine, but I won't say for how long. Shifts are soft when hot, harder when cold, IMO the soft shifts may be the 1st indication of slippage, but the shifts are still crisp with no increase in rpm. Actually, of the 83000 miles, only about 1000+ are with a loaded trailer, 5 times at 2-300 miles each. But, I think 1000 miles all at once against the typical 20-30 mph Kansas headwind would have killed it. Another 1000 empty. I always keep the fluid changed. Transmission guy says a lot of the heat comes from the lockup torque converter unlocking, he says there is more fluid flow with it locked, that's a new one on me, it locks and unlocks in both 3rd and overdrive, so driving in 3rd doesn't help as much as I thought. -- someone said there is a kit for that. What I am going to do for now is--nothing. Once I get the urge to buy another distant tractor, I am probably going to get the gears changed to 3.73's, rather than 4.10, from the current 3.42 (the original salesman mentioned that to me 13 years ago, but I didn't like the way the 3.73 truck I should have bought was equipped, and at that time had no intention of towing). Will probably get a bigger oil cooler. The 3.73 ratio will probably improve mileage because of less shifting, even empty, the 350 TBI is a little underpowered for the way I drive (empty or loaded) it should help that some. I have no desire to trade the truck, the truck is in better condition than many 3-5 years old that don't get the care this one does, if the trans gives up, it is simply bullet biting time, and a rebuilt transmission. As the saying goes the vehicle has served me well, it is far from dead.
