First heavy load evaluation

[OBJDOG]

Hello all!

I just put my 05 King ranch to it's first real work. She's my daily driver so she spends a lot of time unloaded so I wanted to run my data by you guys on today's 3.5 hour drive with about 500lbs in the cab, 1,000lbs in the bed and 5,500lbs in tow.

Outside air temp: 100F
Roads: Rolling hills on back country roads.
Speed: 45-60 depending on hill.
EOT: 203-217
ECT:198-210
TFT: 169-172
MPG: 12.5

One thing I noticed is that even in tow/haul mode, the tranny would still go into O/D on long straight stretches. I thought in T/H mode it wasn't supposed to go into O/D at all. The only diff I noticed in T/H mode was that the shift-point was moved up to about 2,500 rpm which definitely helped getting her up to speed from a stop.

So do these numbers look good?

Numbers seem ok to me. I too was under the assumption that the T/H would turn off the OD but I may be wrong.

[MikeThompson]

Tou/haul does not turn off OD. What you noticed about the shift point is what it does. That keeps it from dropping in and out of OD so much.

Thanks for the info! Spending a little time in O/D definitely helped with the MPG so I'm not going to complain! I just thought T/H mode kept the tranny from going into O/D.

It was pretty fun to watch her pull that trailer and act like there was nothing there. Only really noticed it when I had to stop since the trailer didn't have brakes.

Good info to know

tow haul locks the TC in earlier gears as well, while i dont know if id call 6500 lbs heavy, the numbers look good for what it was pulling

Yeah, I really don't enjoy the shift points of the Tow/Haul, but the engine brake when braking is very helpful! It works really well in conjunction with a custom tune with a Jake Brake!

I towed my travel trailer over a mountain pass for the first time with my edge insight. My trailer is a 25'. The only mods I have are exhaust, intake, and 1 size larger than stock tires. Max temps were 235 eot, 215 ect, 1175 egt, 175 trans. These were the max temps and were not sustained for more than 15 minutes at a time.

I was curious about the transmission as well, one of my first posts on here but some good info if you're curious BASIC 5R110 info please

Those numbers are very good. your oil maxed out at 217 and coolant at 210! and the transmission is nothing. There is nothing to worry about at all.
