CVT overheating--auxiliary cooler?
It's been REALLY hot in CA lately, and on long drives (long for me, 30-50 miles), my CVT is overheating. I'm wondering if anybody's added an auxiliary cooler to keep the CVT from overheating. And if so, how does it perform in the cold winter months?

But, how many miles on car, ... on tranny fluid, ... how many miles since CVT fluid level has been checked? If all's good, think back, has your CVT tranny fluid been last serviced by a non-Ford shop? Even a while ago? If so, step 1 - comes to mind - replace the tranny fluid with assured new Ford 500 CVT fluid - which is pale blue-green color out of the bottle. Here's why, in my experience. On a Subaru, I had a tranny overheat warning come on when it was 22F outside and I was doing steady 65 mph in Montana. So like you ... I thought WTF? Then I recalled that the last Subie tranny fluid service had been performed at an independent shop. I took car to Subie dealer and had them do tranny fluid flush; the overheat warning has never been seen again; I still have the car. So the independent shop put in the wrong fluid, and it showed up, a long time later, as tranny temp overheat. |

So you're talking a 2005 - 7 Ford 500...? Mine's a 2006 with CVT - seems strange to me too.

2006 Ford Five Hundred Limited AWD w/ CVT. Has about 120K miles, according to the owner's manual, the CVT is a sealed unit.
When I got my F500 I looked at the color of the CVT fluid; it was medium/light brown. So I right away did two drain and fills, separated by a bit of driving, when I purchased the car. Each drain and fill of the CVT fluid replaces 5 qts of the listed 10 qt capacity (50%); so two result in 75% new fluid (assuming you use the tranny for >5 miles in between for mixing) and three would result in 87% new fluid. |
So I have a question in regards of this thread I have a 2005 mercury montego same draivetrain and all as the f500 mine is FWD with CVT does this over heating result in the transmission locking itself in gear while you are driving usually check transmission light comes on when it happens cause mine has red fluid in it instead of blue green fluid if so this will help figuring out whats wrong with mine

Check your fluid level and color.
Pull fault codes. Report back. |
Suggest also confirming that your FWD tranny fluid is same as spec'd for my AWD tranny. Ford part number comparison of the fluid would do, or maybe a call to your Ford dealer parts desk. I'd expect the same fluid, but ...
