Description of the problem | When driving down hills and manually downshifting to maintain the legal safe speed the transmission will freewheel for several seconds around 45 mph and will not downshift until 53 mph. At first service visit, dealer updated shift programming for the transmission, with no improvement. At second visit, jeep service wrote on invoice "6886 normal vehicle characteristic. Verified customer concern. Going downhill and manually shifting, engine and vehicle speed may increase before down shifting. This is due to a dog clutch being used for that gear, and requires engine speed to increase in order to engage that clutch. No fault codes, no service bulletins or star cases for this concern. Tech and shop foreman road tested vehicle confirming normal operation as compared to like vehicle." several times when descending a moderate hill in san diego, a hard brake application is required to bring the vehicle under control so as to avoid a rear end collision with a vehicle in front. This is an unsafe design fault of the zf 9-speed transmission. More than 500,000 zf-9 transmissions have been recalled since 2014, and safety problems continue. |
