After about 5 hours of flawless highway driving, my Freestyle displays either AWD or transmission warning. Then, I can't go faster than 50 mph even with pedal to the metal. Any ideas? Thank you!

probably the oil rings on the pistons but might be one of the heads , not good either way

If you don't have a obdII code reader, I would take to autozone and have them check for stored obdII codes they do it for free even if check eng light is not on, and look them up on the net just type in the codes on the search ex ford escape p10442(whatever codes show up) and you should get problems associated with codes. It could be a number of things from a bad seneliod to the tranny pump, you would need to get a diagnostics test done to know for sure from dealer AMCO, or other facility that does transmission work it runs around $100. ope this is useful.

Maybe check for loose u-joints, transmission mount, or carrier bearing if you have a two piece driveshaft.

i own a 2003 vue. it happened to me and finally the tranny went. it was a sealed transmission(cvt)do you have a dipstick to check your transmission fluid.if you dont, get saturn to look at it.a new one is 6000.00.Just hope you have a warranty.
