First pull with mod'd '05
Picked up a new-to-us travel trailer and got the chance to pull it about 100 miles last night. Was running with dfuser's towing tune. Ended up with a couple questions you folks might be able to help with:
1. Tranny temp made it's way to about 180, and pretty much stayed there, even when I spent a fair amount of time with torque converter unlocked. Is there some type of valve that opens up more flow to the cooler at that temp to try and maintain that temp? I have been able to push it up to 200 pulling a liquid fertilizer trailer (~ 15,000# in and out of farm fields), so I know the gage will go higher.
2. How bad would the shift quality be if I asked dfuser to put together a tune that locked up the TC in 4th, 5th, and 6th? Some of the hilly roads around here aren't too conducive to pulling in 6th, but whenever it drops down to 5th, it unlocks the TC until I get up enough speed to get it locked in but not fast enough to shift to 6th. Maybe it could briefly unlock the TC during the shift, but then lock it right away.
Was fun putting the girl to work (though I never got over 1000 deg on the Pyro, so I really wasn't working it), but burning $4.50 fuel kind of hurt.
