Hello all, I posted this on another forum with little luck so far. Does anyone have a slight jerk when they let off the gas around 20mph? It's very minor. I've driven it past 20mph and the upper speed range doesn't have this issue, even higher rpm's so I'm starting to think it's not a motor mount issue?
It's like a manual car, when your in first/second gear it's really sensitive and bucks because it's in a low gear perhaps? Thanks!

Minor jerk when releasing gas? At least it will get a lot of reads just on the title alone!
But seriously, we need to know year of MDX for any return of suggestions.

07' MDX

I'm thinking it just maybe nothing as I was watching it, it seems the jerk was just the transmission shifting, I don't get why it would shift up when I release the gas.

It has to be the trans cooler!

^^^ negative, it was doing this before the transcooler. What made you think it was that? It's at the dealership now so I'll update when I get it back.

Sounds like it downshifted to engine brake when you let off the gas.

Ok, had the dealership check it out, they couldn't find the problem, they said everything was great and the only thing they did to it was a software update to the transmission. Ironic thing after I got it and started driving the rpm's were bouncing like there was a vacuum leak. But it drives fine now, disconnected the batter overnight to see how it will turn out in the morning.

I really don't think it's a torque converter issue, had the dealer checked it out. I'm thinking it's a simple mount or throttle body position sensor.

Update, this seems to be the characteristic of the car, i've driven two others and still noticed the same issue, went for a ride with the shop foreman and the service manager, all stated that it was normal.
