Smile I drive in NYC

When I am in the city the exhaust brake kiks in while driving slow and jerks the transmission with the engine braking on. So while doing city driving i turn it off bud... You can feel the exhaust braking power jerking the tranny. Maby it's because my Dodge has so much power...

Then you have bigger problems....... I've had 2 6.7's and drive the EB on all the time and don't have this jerking problem you are talking about so you have something else going on.....

The jerking is the converter locking up if it isn't already, usually in third gear. This can be fixed by easing of the go pedal.

2012 CCLB carli, firestone, H&S, flopro/magnaflow, h2s, coopers, b&w, and some Draconian tunes to wake it up.
Next: 2nd gen swap w/ s465 and maybe some more fuel to really make this tranny hate life

Are you running EB with Tow/Haul mode? If so, that would explain the tranny action.

Question No Tow Haul Mode

Not using tow haul mode when the jerks happen, only the engine brake. Only happens in city driving.
