Did I toast my tranny? 99 F250 7.3 4r100

By my instruction, my wife was following me up to camp (I was driving a bus w/ 40 kids) in our 99 F250 7.3 w/ 104K on it. She was pulling a 14' trailer w/ a quad and some luggage (probably @ 1500 lbs total). Anyways, about 40 miles into the trip (uphill all the way, with hill climbs at @ 10-20 mph because of the bus) the tranny overheated, and @ 10 quarts of fluid "escaped" from the tranny. I had it towed home, and then when I returned from camp, I replaced the fluid, and I've been driving it for the last 3 days. The only thing different that the tranny does now is kind of slam into 1st gear- and only when I goose it. If I just ease into it, the tranny is smooth. It doesn't slip in any of the gears. Is this a repairable problem, or do I need a complete rebuild??

Also, anyone hear of Charles Farland in Olivehurst, CA? He says he's been rebuilding trannys for 30 years.

Thanks for your advice.

My wifes truck is an early 99, I mention this because the tranny fluid goes thru a real small trans cooler and does not even go thru the radiator. Not that the radiator is much help but some of the 99's have a real small cooler. Actually all the 7.3 trucks came with small coolers. (I believe) But my 01 goes thru the radiator too. My wifes coworker had the trans dump all its fluid out twice(also early 99) But 50k later it still works. MAybe give it a fluid and filter change and get a trans cooler from a 6.0 truck?

I was wondering about the transmission cooling system... I can see a cooler that is behind the first radiator (I assume the first radiator is the a/c radiator). It sits low... It is about 4 inches tall and about 30 inches long. I guess this is it????? It doesn't seem like much of a cooler. And like I said, my wife was going pretty slow... So, an aftermarket from a 6.0 would be better? Does it bolt right up?

that is the power steering fluid cooler I think, the one behind the license plate. the trans cooler is behind the radiator down low. A after market or a 6 liter trans cooler would be a great up grade for your truck and I believe it does bolt in. Do a google search for it. Its a popular up grade.
