Hello, just lately when I let off the throttle after cruising on the highway for a while, it like lets off hard (kinda like I touch the brake for a second) and then it seems to coast normally. It happens in about a second. Do you think it could be the torque converter clutch sticking a little? It only happens occasionally (for now).
Thank You, for any and all replies.

 

any chance you are in tow mode?

 

Update....just took it on a 600 mile trip....it never did it once...I just don't know. It's not the Tow Haul mode, that seems to work fine.

 

I am no tranny knowledge. What you described sounded like when you let off the throttle in tow/haul mode. The tranny is programmed to act like an engine brake to help slow heavy loads.
