Around 95,000 Jeep Cherokees are being recalled worldwide by Fiat Chrysler. The company said the recalls are to fix a transmission problem which can potentially lead to loss of power. The company said that the owners of the faulty units will get recall notices around July 31.
The company issued a statement saying, 'A review of customer data prompted an FCA investigation that discovered a driveline connection may, in certain circumstances, slip. Should this occur, it may lead to loss of propulsion and prevent the transmission from engaging PARK when the vehicle is stationary.'
The Jeep Cherokees that are being recalled have been produced between 2014 and 2017, mostly sold in United States and Canada. However, there have been no major incident so far with Cherokees yet due to this problem. The company documents posted by the US National Highway Traffic Safety Administration says it has one report of a crash with no injuries. It also has 829 warranty claims and three field reports due to the problem.
The Jeep Cherokees being recalled are mostly all-wheel-drive models produced between 2014 and 2017. They all have a two-speed Power Transfer Unit, also known as the Active Drive II or Active Drive Lock. The system simulates the sort of two-speed transfer case found in many part-time four-wheel-drive trucks and SUVs. The features are optional on multiple trims and standard on Trailhawk models.

Fiat Chrylser said it will install updated software in the faulty Cherokees to ring an alarm when such malfunctions occur again. It said that when the SUV is on the move, the system will automatically shift power to the rear wheels to maintain propulsion. If a malfunction is detected while attempting to shift into park, the system will also apply the parking brake automatically to prevent roll-away.
Fiat Chrysler also said that only one per cent of the Cherokee SUVs face this issue, and most are covered by five-year powertrain warranties. For 2014 and 2015 models, transmissions are covered for 100,000 miles. For 2016 and 2017 models it’s 60,000 miles.

American Motors Corporation (AMC) and Jeep used a variety of transmissions and transfer cases.

- ^The 'M-10' is not the actual Borg-Warner designation. This is a variation of the M-8 that uses a TV (Throttle Valve) cable instead of a vacuum modulator to control internal transmission pressure. The TV cable also serves as a 'kick-down' control when fully pushed in under a predetermined speed. Most parts interchange, but the case and valve body are different to accommodate TV cable or vacuum modulator.
- ^The M-36 and 37 have provisions for an external oil/water or oil/air cooler. Heavy-duty and towing package configurations came from the factory with oil/water cooling instead of air cooling. An aftermarket air/air cooler can be added. Some were added by dealers at purchasers request. Extra internal parts may be required for an external cooler.
Early Jeep Automatic (1970-1971)[edit]
- Jeep Wagoneer/Grand Wagoneer
Kaiser Jeep was purchased by AMC in 1970.
The Buick 350 cu in (5.7 L)V8, AMC 232 I6, and AMC 327, 360 V8 engines in the FSJ Wagoneer and trucks used a 'nailhead' pattern TH400—also known as a 'unipattern,' as it was used by many other manufacturers (including Rolls Royce and Jaguar) with an adapter ring—from 1965-1972.
The Buick 225 cu in (3.7 L) V6, available with an optional automatic transmission in the Jeepster Commando, used the same 'nailhead' pattern TH400. Starting in 1973, AMC discontinued the use of the adapter ring, as it sourced a TH400 case from GM with the AMC bellhousing pattern already cast. The TH400 AMC case was used until the end of 1979 model production.
The 232 cu in (3.8 L) I6 used in 1970-72 Jeep DJ 'Postal Jeep' was backed up by the Borg-Warner T-35 3-speed automatic. At the time of the acquisition, Kaiser-Jeep was using a GM 2-speed Powerglide transmission in the DJ-5A (with the GM-sourced 2.5L I4).

Jeep Transmission Parts
AMC phased out the use of the Borg-Warner Shift-Command transmissions when the company transitioned to using the Chrysler Torqueflite. AMC branded the Torqueflites as the Torque Command using the previous naming convention - both the A-727 and A-904 (including the later 999 derivatives) were used with the addition of the Aisin-Warner 4 (AW4) used with the Jeep XJ series. Jeep vehicles throughout the 1970s used the GM Turbo Hydramatic 400 - the use of the GM transmission goes back to 1965 where Kaiser-Jeep installed it in the AMC 327 cu in (5.4 L) V8 in the full-size Wagoneer and J-trucks.
The TH400 was phased out for the 1980 models, when the A-727 replaced the TH-400 as the only automatic transmission option for both the SJ Wagoneer/Cherokee wagons and the J-10/J-20 trucks. Internally similar to the Chrysler A-727, the case was one-piece, cast with an AMC pattern bellhousing (not interchangeable with a Chrysler pattern A-727).
