too high of gear bogging engine

While doing 45-50mph(ish) crusing, itll go into 7th gear and the rpms will be around 1100-1200. Theres almost a groaning type of sound coming from the cabin because the rpms are so low. If i down shift into 6th, the rpms go up to (about) 1500 and it smooths right out.

Our 14 has 48k miles on it. Mainly highway driven, but for the in town comutes it can be annoying. If i drop it down to 6th i have to remember to up shift after i come to a stop.

Anyone else notice this?

Re: too high of gear bogging engine

Every owner notices it... some are bothered by it more than others. It's designed that way for better fuel economy.

I'm not bothered by it and I don't really notice any engine bog.

Re: too high of gear bogging engine

Figured it was for mileage. Looks good on paper but wait until these thing get closer to 150-200k miles. The cabin will be a rattle trap all to save a 1mpg lol

Turning off ECO will help a little, and this software flash TSB below can help the low speed lugging a little also. It doesn't totally get rid of it but it does lessen it. The wording on the TSB is terrible and confusing( there are a few threads on that) . But cutting through and deciphering what they are trying to say it is supposed to improve shifting. I had it done thinking it was going to fix the ECO button retention which it didn't but it did help the lite throttle low speed lugging.

If you don't have it have your dealer do the flash the next time it may help you out some.

Re: too high of gear bogging engine

Likely the MDS kicking in -running on 4 cylinders instead of 8.
