automatic transmission shifting procedure
Just checking my methodology to see if "all" agrees. I am towing a 5000 lb TT with a 2006 Chevy Trailblazer with the 5.3 vortex v8. I tow in 3rd. When going up a steep hill, I wait until the comput...

Bryan, I am curious, do you know what gears the 6R75 locks up in? I know when I am going slow like through a parking lot, it FEELS like it is locked. It will "chuck" some with throttle tip in and out like when driving around my car in 1st. Same if I am driving in 1st or 2nd going up a hill and feather the throttle, tip in and out is not as smooth as I would think if the converter was unlocked. If in 2nd or 1st and I let off the throttle, the tach drops in a linear manner with the speedometer until I am almost stopped where it will pop up a little like the converter is unlocking.
Whatever it does, I really like how they drive. I just wish I had the full manual control like the later ones, I would love to lock out 6th but NOT 5th for towing on the flat.
I believe it does. I think all of the Ford with drive-by-wire lockup in all gears. The "pop" you notice during deceleration is probably the fuel injectors firing again. Normally during coasting your T/C is locked and the engine is completely de-fueled until it drops below a certain RPM.
If you get a 5-star Tuner, you can have a 6th-gear lockout enabled for towing. I know some guys like this feature for the 5R110 behind the V10, because it also does not have an overdrive lockout.
