NHTSA Complaint #11627324 — 2020 FORD EXPLORER

Oil change and service check was completed on 20 Nov 2024. Maintenance record shows transmission fluid levels passed inspection. Issue started on 23 Nov 2024. Driving at speeds of 65, 55, 45, and 35mph on a highway. When accelerating to the speed limit, a hard shift was noticed at around 45mph. When decelerating to stop light or to reduce speed due to traffic, a very hard shift was noticed. Around 25mph is the hardest shift. On 25 Nov 2024 while increasing speed from 42mph to 50mph, a very loud metal clanking sound was heard at the same moment a hard shift took place. A check engine light came on briefly and went away within one minute. I took the vehicle to a transmission repair shop to inspect the codes. Two transmission over temp codes were shown without the check engine caution light on. The codes were cleared and the vehicle was taken for a two minute test drive. Upon returning to the shop, when the vehicle was put into park, a rough gear shift was heard and felt throughout the vehicle. The two transmission over temperature codes were populated again after the test drive.
