Hey all,

Our MKC has been having a lot of problems lately. For the past few weeks, the car would refuse to accelerate, even with the pedal half way down or more. I thought that it was because the transmission was cold: Boy was I wrong!

Few days ago the wrench light came on and stated there was a powertrain fault. Took it to the dealer the next day only for them to realize that the transmission was tearing itself apart as there were metal shards everywhere.

Get this: our powertrain warranty expires in 10 days! If we didn’t do this sooner, we would’ve had to shell out a lot of money.

But still, 68k miles?? My 2009 Focus is at 135k miles and the transmission is great! Then again, the SelectShift transmissions were known for their problems.

Has anyone else had to get their transmission replaced or have they ever had the car just not accelerate? I forgot to note that sometimes when the car did accelerate, there would be a sort of grinding sound. It might’ve been the transmission, not 100% sure.

92,000 miles and I tow a boat right at the rated limit. Maybe twice a year at a light the trans will spin like neutral then pop in, but no other problems

Wow, funny this is at the top of the "Recent Discussions" list.

Yesterday morning, our 2015 2.3 Reserve had a rough day. My wife backed it out of the driveway as she normally does and put it in Drive. She felt big THUD and bang sound. Then the car would barely move on it's own power. She barely got it in the driveway and took my car to work. When I got home, I took it for a drive.

First, I checked for codes, none were stored. Then I took it for a drive. Wow, the range of noises, feeling and symptoms was crazy. They ranged from full on power loss, to shudder, RPM Surging, to slipping and finally slipping then like I neutral dropped it. Even sitting at idle it felt fine, then BAM the whole car shook with a THUD and RPMs bounced from 1500 to almost stalling.

I dropped it off at the dealer last night and awaiting diagnosis.

No CEL, no Wrench.

This is the only thread where I've found a failure of the transmission. I found the TSB for the Torque Converter (which this definitely feels like a failing TC), but that's not for a failure, but a noise on 2nd and 3rd shift.

It only has 30K on it.

Thank goodness for an extended warranty, as you know Dealer's find ways not to cover things under the Powertrain warranty.

Finally got repaired! Picking it up today. Going to have to get rid of our loaded Nautilus loaner sadly..

They ended up rebuilding the transmission. I’ll update if the transmission feels better.

UPDATE:

Transmission feels a lot smoother! It also feels like the car accelerates faster now... Let’s hope this one lasts...

Transmission dead at 37500!

Glad to hear I’m not the only one. Last week, as I was leaving my house for the mall, my car lurched at a nearby stop sign and the wrench light came on. I was a few blocks from my house, so I slowly drove back home at 5 mph, coasting mostly thankfully due to a slope toward the house. The next day, I tried to drive the car to the dealer but the car accelerated, lost power, lurched, etc. so I immediately pulled over and called a tow. No wrench light this time, nothing. The dealer first said it was a solenoid three days ago and ordered the part (I doubted it but they had my car and were dictating the diagnosis process). Called today... the solenoid was fine. The transmission fluid was “burnt”. They have to take apart the transmission, diagnose/repair and rebuild it. At 37500 miles! I bought it used so who knows what the previous owner did or if this is a Ford issue. I did all of my maintenance on schedule. At least it’s covered under the powertrain warrantee, and my extended warranty got me a rental car for 10 days. But they say 2-3 weeks for the repair. Very unusual for me with Ford/Lincoln. Not sure if I’ll trust my MKC afterwards. ☹

I Have A Transmission Shop And.....

This transmission series has been around for a while and was a joint venture between GM and Ford. The GM version, 6t70 had an issue around 2009 of broken wave plates and premature failure. Ford had thicker wave plates inside the unit. I think it was 2010 GM fixed the issue. Anyways, the 6F50/55 unit is not that good. My 16 MKC has 30k on it and the fluid is really dark, not burned but just excessively dark. The first time I changed it it had 18k miles and was dark then too. It shifts okay but I am not taking any chances. I have a rebuilt title so no warranty. My solution is to run the BG products in my transmission and go as long as I can. Since I am under 50k miles, if the unit actually fails I will get $4k towards transmission failure coverage which will fully cover retail cost of a rebuild. Also, if I service it every 30k and the coverage stays active forever.



I think the domestic units built these days are garbage. The only manufactures seeing high mileage without major repairs are Toyota, Hyundai, and Kia. It's sad. Honda is getting better but they were plagued with trans issues at one point, Nissan CVT's are still junk, Mitsubishi, Subaru, you don't see them often but not as many out there either. BMW has issues prematurely, Mercedes is great but the service cost is high. Anyways, the MKC unit is 100k mileage unit if you are lucky.

2ND time for me

Total rebuild (took 2.5 Weeks) at 40K miles. Now again at 59,333 and three months left on the warranty and it is starting to do the same thing again. I want to push for a new trans but due to internal ford policy, they fight it to death. But now I have no confidence that a rebuild will fix anything long term. Don't want to be in the same situation at 18 k more miles later and be looking at a 3/5K bill to fix it again.

It looks to me like the BG coverage for transmissions (for plan 1 - where the initial service is performed before 50k miles and every 30k thereafter) is coverage up to $2000 if you have a failure on the transmission. That is a good amount of coverage - but I do wonder how cooperative they would be about paying out in the event of a problem. Anyone know of someone collecting on a failure?

I can’t speak from experience with Ford/Lincoln but my Jeep Wrangler developed a leak in the oil cooler that required an immediate repair. The repair cost is roughly $1000. My Wrangler was 2 years out of powertrain warranty and I was concerned. I decided to call FCA customer support and explained my situation and I nicely asked for an accommodation. I also pointed out to the person that failure of that part was fairly common. The customer service person took my VIN and said I will be contacted in a few days. I had my jeep regularly serviced by the dealer including all oil changes. I got a call back asking me to take it to the dealer for inspection. Basically she wanted the dealer to verify the issue and inspect my vehicle to verify I maintained it well. A day later I get a call from the customer service person and I was offered the repair for a $100 deductible. Moral of the story try other options beyond the dealer. A bit of persuasion and your enthusiasm for the brand (whether real or not) can go a long way.
