Okay, MKC was added for next time. There are 7 shift solenoids int eh valve body, which one are you changing? The solenoids are removed by using a pair of needle nose pliers to remove two roll pins which allow the solenoids to be removed. You generally do NOT remove the transmission to replace the shift solenoids, but you do have to get into the valve body/solenoid body area, which is accessed from the bottom (pan off).
This is the practical, “how the job really goes” sequence:
1. Confirm transmission type (most MKC are 6F35 6-speed).
If you’re ordering parts, look up by VIN so you don’t end up with the wrong solenoid body generation.
2. Disconnect battery (you’ll have connectors open; you don’t want a wake-up event).
3. Raise & level the vehicle.
Level matters because you’ll be refilling/checking fluid level properly.

4. Remove the transmission pan. Expect a mess; keep everything clean - valve body work hates dirt. Drain the ATF (catch pan, measure what comes out).
5. Remove/inspect the filter (if applicable) and pan magnet(s).
6. Unplug internal harness/connectors as required and remove the main control (valve body) to access the solenoid body.
7. Remove/replace the solenoid body / solenoids (many techs replace the whole solenoid body/leadframe assembly instead of individual solenoids, depending on failure/codes).
8. Reinstall with correct torque sequence. Example guidance for 6F35 valve body fasteners is typically around 89 in-lb (10 Nm) in sequence (don’t “feel it out” on these).
9. Reassemble with NEW gaskets/seals (pan gasket, separator plate gaskets if disturbed, etc.).
10. Refill with the correct fluid (commonly MERCON LV spec for this family).
Important: solenoid strategy/programming + adaptive relearn (if required).
The 6F35 uses a solenoid body strategy that must match/program correctly or you can create shift issues even after “good” mechanical work. Check out the images (below). Please let us know what happens. Ken
