While driving on the freeway I noticed that I could only go 45 miles per hour and when I gave it more gas the rpms would increase to 5000 but the speedometer would not move at all past that speed.

Another thing....The exhaust in lower gears sounds kinda like those ricer hondas with those mufflers. The sound of the exhaust seems to have change a bit.

Maybe it is not associated...not really sure.

Auto trans was purchased from Everdrive (used) and replaced like 2 months ago and seals and filter changed etc....And got a nearly new T-Case.....These are the only changes that I did!

Was wondering if it could be the timing belt?????

There also seems to be a general lack of power from the whole vehicle in any gear.

What do y'all think?

Thanks
Mike
