Give final opinion on 2nd gear braking

[Mark Kovalsky]

I dug up this thread because I had a PM a couple days ago asking me to comment. I didn't notice that this was an old thread.

The coast clutch will activate anytime the OD is turned off, or the shifter is in the 1 or 2 position. It can NEVER be on when the trans is in fourth gear.

From actual measurements having the torque converter locked adds about 10% to engine braking.

The shift schedules with the cruise active are a bit different, but the cruise does not force downshifts or modify engine braking.

I have towed about 60000 miles with my Montana(10.5K) and used the TC Lock and DIY exhaust brake and never a problem going down steep grades. So I recommend an exhaust brake with TC Lock. Many brakes to choose from.

Maybe my brakes are dragging really badly slowing me down on descents even though I am not touching the brakes.
