Replying to: beachgirl11 (Apr 06, 2008 10:51 am) I just got my car back after a week at Aamco. They tested just about everything and determined it was NOT the transmission as the dealer had suggested.   They tested the computer and it was fine. Since they re-installed the computer, they could not replicate the problem(s).   I am hoping it was a connection issue. So far-so good.   Let me know how your issue turns out.

Replying to: tharroun (Apr 09, 2008 4:12 pm) THey kept my car for 2 days & told me it was the Fuel Pump. I recently ran in to a friend w/ a Mercury & she had the same issue & hers was the fuel pump as well so I am hoping it is repaired for good. It has been fine all day but I have only done local travel. Good luck. fyi- at 50K miles I had to have the transmission replaced so I really cant wait to get rid of this car!!!! but it does ride well when all is ok and I love all of the storage.

Replying to: beachgirl11 (Apr 09, 2008 5:12 pm) The fuel pump might be a good idea except for the bucking when braking. Hopefully, all is good for now.

Replying to: tharroun (Jan 11, 2008 4:55 pm) My 2005 500 had this problem which was caused by a sticking valve in the transmission which had to be replaced. I had an extended warranty and my Ford dealer covered the deductible to keep me happy. This is a known problem - something to do with the transmission fluid.

Replying to: adams430 (Aug 13, 2007 3:52 pm) Can you tell me if this problem happed again and what they did? I was just told they reprogrammed the board and the problem was back in a day now I am being told I need to replace the whole dash cluster. Which is 500.00 for a car that is 3 years old.

Replying to: 500gal (Apr 13, 2008 12:14 pm) Since they reprogrammed the computer, and are now telling you it's the dashboard - they clearly do not know what the problem is and are guessing at your expenses. If they are sure the dashboard is the problem have them give them you money back if it doesn't work. FYI - I had this very same issue with a Ford Contour. NO ONE (even some of the best diagnostic shops in my area) could figure out what it was.   I got rid of the car.

Replying to: wtkjd (Apr 13, 2008 11:27 am) Did you have the same problem, ie vibrating while braking and when accelerating at high speed?   Also, do you have any other details about the fix? If I was going to relay this info. to my transmission guy-which valve would I refer him to?   Thanks. Replies to this message: user777 (Apr 15, 2008 9:07 am)

Replying to: tharroun (Apr 15, 2008 5:01 am) is it possible you have an EGR valve or clogged EGR port problem? google.

Replying to: wtkjd (Apr 13, 2008 11:27 am) Which transmission are we talking about? The 6spd or cvt? Replies to this message: yak2 (Aug 07, 2008 4:54 am) tharroun (Aug 07, 2008 4:16 pm)
#112 of 182 Ford 500 Transmission Problem by theelee Apr 24, 2008 (5:25 am)
My 2005 Ford 500 down shifts for no reason at highway speed. At 70+ on cruise control, in traffic when you tap the brake to slow when you touch the accelerator again, lightly, the car down shifts really hard with a loud sound. The Ford technician who rode with me to trouble shoot was really impressed with how hard it is. They say I need a new valve block for $ 1,000 parts and labor. Any one else have this happen.
