Todd2018 Posted August 9 Report Share Posted August 9 Hello Everyone New to the forums. I recently purchased a new to us 2018 Ford Edge sport. Love the Edge, but I am having a particular problem. Originally it was a slip from 2-3 gear and less pronounced between 1-2 gears. I've done 2 drain and fills on the transmission but now it seems like it slips/flairs between 1-2 and 2-3 but intermittently. I'm wondering if I should be considering a reset of the transmission adaptive values? Looking for opinions. Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted Saturday at 07:00 PM Report Share Posted Saturday at 07:00 PM Possible Causes could be worn Transmission bands, a problem with the TCM or software and low or worn out transmission Fluid. It's possible the torque converter didn't have enough fluid to transfer power properly. Also transmission solenoids control fluid flow and a faulty solenoid can cause erratic shifts. Possible easy fixes are doing another drain & fill and/or reflashing the TCM. My suspicion is the previous owner didn't change the xmission properly. Which makes me think that they may not have done any maintenance. I'd be cautious and CHANGE ALL FLUIDS. •Have you checked for transmission codes? (Might narrow it down if a code was set.) •How many miles are on car? Quote Link to comment Share on other sites More sharing options...
Todd2018 Posted Saturday at 08:05 PM Author Report Share Posted Saturday at 08:05 PM 87,200ish miles. I haven't checked for codes but I will and report back. I've done a total of 3 drain and fills. Do you by chance know the proper procedure for checking the transmission fluid level? I've seen some things on line state hot with the engine off but others state hot and running. The owners manual doesn't state that it has to be running, just hot. I'm skeptical of checking it running because you have to remove the air box to get to the dipstick.

enigma-2 Posted Saturday at 09:34 PM Report Share Posted Saturday at 09:34 PM The procedure I've used since a teen back in the 60's: park car on level ground, start the engine and let it run (until fans come.) Shift into each gear. Hold for a few seconds between shifts. Return to park. Shut the engine off. Remove the transmission dipstick, wipe, reinsert, remove again and check level. On some current Ford models, you'll need to partly disassemble the engine to reach the dipstick. (OK, that's an exaggeration, but it just kills me how stupid some engineers are. On my 3.5 its easily accessible and prominent. It screams "here I am, pull my finger". On others, "nothing to see here, move along".)

Todd2018 Posted Saturday at 09:50 PM Author Report Share Posted Saturday at 09:50 PM Would you recommend the level be at max after checking it this way or just in the cross hatch area above minimum? I've been taking a quick drive around town to a couple stores and back. Shutting it off and then going through the process of removing the air box and then checking the fluid level.

Todd2018 Posted Saturday at 09:59 PM Author Report Share Posted Saturday at 09:59 PM Of note possibly, if I'm easy on the gas pedal up until after it shifts into 3rd it seems to shift fine Quote Link to comment Share on other sites More sharing options...
