rritch01 Posted January 26, 2021 Report Share Posted January 26, 2021 2007 Ford Edge SEL. When its cold, the transmission seems to take longer to shift. All gears seem to have the issue. Worse in cold weather it seems. Ideas? Quote Link to comment Share on other sites More sharing options...
Perblue Posted January 26, 2021 Report Share Posted January 26, 2021 Depending on how cold, cold is where you are. It's -30C here so the transmission fluid is super thick and not moving around well so the transmission will shift slower. You could also be low on transmission fluid or the transmission could be worn and have said issues showing when cold. Quote Link to comment Share on other sites More sharing options...
rritch01 Posted January 26, 2021 Author Report Share Posted January 26, 2021 Not that cold here in Kansas City that often. I'm thinking of changing the fluid and see if it helps. Quote Link to comment Share on other sites More sharing options...

The transmission in my Malibu was a little slow shifting this morning. Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted January 27, 2021 Report Share Posted January 27, 2021 Change the fluid completely, and use Valvoline Maxlife MultiVehicle ATF (red jug). It is basically Mercon LV viscosity but perfectly good in Mercon V situations. If it works for brake fluid, why not trans fluid Quote Link to comment Share on other sites More sharing options...
rritch01 Posted January 27, 2021 Author Report Share Posted January 27, 2021 I'm a bit hesitant to use anything but manufacturer's fluid. The reason is that a friend of mine had his changed on a Honda minivan at a Jiffy Lube and ended up needing to get it rebuilt. Looks like you have a lot of responses on Edges, though. Guess you know your stuff! Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted January 27, 2021 Report Share Posted January 27, 2021 My reliable source on this is MACT (you can see his videos on YT under the MACTFORDEDGE channel). He has been running Valvoline fluid for the longest time. But yes, you should go with what you feel comfortable. New fluid is the important takeaway here.

enigma-2 Posted February 4, 2021 Report Share Posted February 4, 2021 This brought to mind problem I had with a rental years ago. I was in Central Wisconsin and it hit -40°f (no wind chill) that night. Everyone else had their car plugged in except me (rental). Think this wad around Rhinelander. Went out at 7am and cranked. And cranked and cranked. And cranked. Wentbin twice to let tbe started cool and me to warm. (Did I mention it was 40°F)? Probably near burnt out the starter. (rental). Finally it fired on 3 cylinders. The 4. Then 5, then after running for a couple of minutes, 6. Let it warm up completely while I sat in my motel room and shivered in front of the heater. Finally got on the road and headed to my first inspection. Reverse was like it had syrup in the tranny. Heavy on the gas and jussssst moving in reverse. Now into drive and it refused to shift out of low. I'm heading down an empty, dark, snow-covered highway, floored, doing 25 mph. Engine red lining, still no shift. So I figure either it blows or it shifts. (rental). It took about 15-20 miles to thaw out and shift. I began to think it would never shift. Just how hot does the tranny fluid have to get anyway? Unrelated, but the tires never thawed out. They took a "set" on the bottom from sitting on the ground. So, thump, thimp, thump down the highway. They were still deformed at the end of the next day when I turned the car in at Minneapolis a/p. Damn -40° is cold. I was never that cold even in northern Quebec Provence. 1 Quote Link to comment Share on other sites More sharing options...
rritch01 Posted February 15, 2021 Author Report Share Posted February 15, 2021 Update - changed the fluid, but slightly differently. Our daughter is in school for auto maintenance and her transmission instructor said to drain and fill, drive it for two weeks, drain and fill again. Its shifiting much better. Thank to everyone for their help, especially WWWPerfA_ZN0W for the reference on fluid! 1 Quote Link to comment Share on other sites More sharing options...
