Problem with Limited Hemi
 
The problem I have is when Jeep is warmed up I am not sure if the transmission is shifting from 4th to 5th and back to 4th. It fills like a rumble coming from the front. It starts to happen at around 40 to 60 mph. If I give it gas it stops, I am still new to this jeep and don't know if it is the MDS system engaging and disengaging or the transmission?

Sounds like MDS, though in comparison to most reviews, i find my MDS transition to be quite smooth.

Would the MDS system send a code if it's not engaging correctly?

typically it will... I do agree too though, it does sound like mds.

Mine used to do this and it was the U-Joint on the front drive shaft. when i gave it gas it stopped and when i let off the gas it stopped. They say the ujoints are not serviceabe but the shop I went to ordered the correct UJoints and were able to get the old ones out and replaced. Drives amazingly smooth now.

I now am sure it's the MDS system because I just got a check engine light for the 02 sensor. I have read that if there is a code sent that the MDS system will not engage. I have not had the problem since, am I correct in my conclusion?

What can be done to the MDS system that would stop this problem?

You can shut off the mds. Alot of people on here do that

You need a programmer

For one-time test: Push Tow-Haul button -or- shift from D to 5 manually. It disables MDS.

This will last until next engine re-start. Then it re-sets.
