2007 5.7 trans problems

Hello every one i am new hear so please bear with me. i recently purchased a 07 grand cherokee limited 5.7 litre. i am new to this MSD and other functions of this vehicle. my questions are: 1- at between 18 and 22 mile an hour in traffic my jeep seems to be shifting in and out of overdrive,had jeep to dealer and they flashed the system,whatever that means,this did change the length of times between shifts, but in slow moving traffic the jeep still seems to go in and out of overdrive,also now there is slower responce when i push on the gas in need of more speed(passing gear)
anyone have any ideas. thanks people

Re: 2007 5.7 trans problems

Sounds like MDS is having some fun with you. You could always try to disable it to see if you get any better performance.

2 quick methods to disable:
1) Hit your auto-stick to the left, putting the gear in 4 or 5
2) Press Tow/Haul

I typically disable it by means of method 1, but i have a Diablosport Predator now, so i can disable MDS permanently in there.

Re: 2007 5.7 trans problems

thanks for the comeback. i got in my machine and took a ride up the avenue using tow haul-no difference. put the jeep in 4th and also 5th gears-no difference. this is making me crazy
