Transmission was supposedly rebuilt back July 26, 3021. Now transmission has had a new dual clutch replaced but other concerns are still there jerkiness on accelerations. In 2021 the transmission was not fully rebuild as per recall. Only clutch assembly was done and not the back end. Which now could be the problem. Second, colonial Ford sated transmission rebuilt has lifetime warranty which a lie. Colonial Ford doesn’t offer lifetime. The service advisors lie about this all the time. Now the car jerks on acceleration after clutch replacement. Dealer and Ford still take no responsibility over the product! The car has 145,000 miles still under the 150,000 mile warranty isssue by you!

Around 50,000 miles I noticed the car would jerk when trying to shift gears , this issue persisted and would only go on to get worse. It started taking forever to accelerate regardless of pressing on the gas, now at 70,000 miles it won’t shift out of 2nd gear when driving over 40 mph, it’s a huge safety issue .
