Never saw those temperatures after installing the 6.0 tranny cooler on my 99 Superduty 7.3 towing a 38’ fifth wheel. That 4R100 transmission is certainly not one of fords better transmissions . Google the fluid change on that 4R100 its very easy , and save yourself some money , I did it a few times during the nearly 16 years I had it .
There is a great transmission builder in Arkansas that specializes in the 4R100 that will put your transmission problems to an end . Brian’s Truck Stop
yes i have heard of him,,, at the time i got the john woods,, supposedly john woods was the west coast expert and brian was the east coast expert,, sadlly i am on the west coast so arkansas is long drive. it soundslike you have done fluid change yourself? how do you get the fluid out of the converter and cooler? never mind, i will google it. thanks
Before I decided to trade in my 99 Superduty, I was going to go with the BTS , instead of the John Woods, from everything I read the BTS was the better tranny build. I actually talked to him about a shifting problem, that was intermittent , and he sent be a valve body, thinking that was my issue . Every rebuild he does he puts in a new valve body regardless, so the one he sent me was supposedly a used one ,but okay. All I paid was the shipping. Never got around to replacing it, seemed to start shifting okay, so I just let it go. As far as tuners again ,probably one of the better ones ,and the one I ran was the DP tuner. It had a tow tune ,as well as others, plus the stock tune as well . I also went with the AIS air intake ,4" exhaust turbo back. The truck ran very well, but short of changing turbos ,injectors etc ,it just didn't have the power in the mountains for a 38' fifth wheel that I would like.
As far as the fluid change ,yes just google it ,its easier then me having to explain it, but yes the old fluid gets pumped out of the converter, and as well as the cooler, its actually as said very easy.
I totally agree, even towing just a 33 foot toy hauler in the mountains is a struggle with my 2001, almost any grade above 5% and I’m in second gear going about 43 miles an hour, one time on a little Highway Inn between Benton California and mammoth, I couldn’t even do that, I was in first gear I barely made it over that little summit. Although I love my truck, I like how easy it is to work on, I like the fact that it doesn’t have all of the smog **** that every other truck has, and I like that I don’t have to put in that exhaust fluid
But I do get a little jealous of the newer trucks in the way they blow by me doing 85 mph up a grade pulling a 40 ft trailer
Yes, there were grades that it was 30-35 in second gear , it had more , but the EGT temperatures would get too high . Didn’t know what I was missing when I bought a new Ram Cummins in 2014 .
