was no longer able, due to age and deterioration of that facility, to be further modified to handle the expected increase in production for the company in 1955 and beyond. A new facility was therefore planned and built for use by
Packard as a transmission and engine facility in Utica, Michigan. This facility was actually built on the N/E corner of Packard Proving Ground Complex on Van Dyke Rd. The facility was sided by both 22 Mile Rd, and Mound. After completion, Packard moved the machinery, and production line for the Ultramatic, as well as its yet to be introduced V-8 engine during the summer and early fall of 1954. This facility therefore produced all 1954 "Gear-Start", 1955 "Twin-Ultramatic", and 1956 Ultramatic derivatives through the fall of 1956 when this facility was deactivated and sold as part of a corporate buyout deal with the Curtiss-Wright Company.

timed high clutch application and low band release over much of the allowable up-shift range resulted in many premature high clutch failures. This situation resulted in an unusual sensitivity to individual driving habits determining useful clutch life. Therefore, while the transmission was designed to physically accept a high torque V8, its control system needed further development. Packard's plans for upgrading the
Ultramatic Drive further were in development for 1957 and beyond. These plans were shelved, however, when Studebaker-Packard was taken over by

In this new DRIVE range, it would use the low ratio and torque converter to start off, switching to the high ratio and ultimately to direct drive as the car accelerated, effectively automating what many Packard drivers had been doing manually with the older Ultramatic Drive.

better to compete with the Dual-Range Hydra-Matic. Functionality was the same; the first Drive position, to left of the 'D equated to High on the Gear-Start
Ultramatic, while the second, situated to the right of D', was equivalent to the Drive position on the Gear-Start, giving the driver the option of starting in either High or Low with automatic upshifts, ending with Direct Drive engagement of the torque converter, thus the

turbine torque converter (actually a total of four turbines were employed) was used to reduce gearing for starting off. At a speed of 15–56 mph (24–90 km/h) (depending on rear axle ratio which affected the rate of governor pressure rise), hydraulic pressure overcame the opposing throttle pressure, as determined by carburetor linkage position, causing the Direct Shift Valve to apply the
70:. The Hydra-Matic was available starting in 1941 and became very popular during the 1946–1948 time-frame, pushing along Packard's release of its new automatic drive. Packard at that time (1946–1949) offered only an Electromatic Vacuum Clutch option, which required manual shifting otherwise. As with most vacuum powered shifting and clutching devices, Electromatic was overall generally unreliable.
187:, and their team had not been satisfied with the improved pick-up of the Gear-Start Ultramatic, and modified the angle of the converter "pump" to allow a higher stall speed thus increasing the torque multiplication better suited to the torque curve of the new V8 engines. In addition, a slightly higher stall converter was produced for the sportier
98:. This "locked" the torque converter, giving direct mechanical drive from the engine to the rear wheels. This became the Ultramatic's definitive feature, eliminating the power-robbing slippage of the torque converter at cruising speeds. On the highway, the Ultramatic delivered the same economy and power as a

breaker; electrical contact problems, wiring problems and other issues were prevalent even when new, and worsened with age. Later models saw system improvements. When the contract was cancelled after
Packard production ceased, Auto-Lite destroyed the tooling, making spare parts for the system unobtainable.

With no
Packard V8s or Ultramatic transmissions being made thereafter, Studebaker would replace the 1956 Golden Hawk's Packard V8 with a supercharged version of its own 289ci V8, and its accompanying Ultramatic Drive was replaced by Borg-Warner's Flightomatic transmission, beginning in the 1957 model

During 1954, and into 1955, Packard Motor Car
Company, later Studebaker-Packard, went on a modernization spree of its aging facilities. It was decided by Packard President James J. Nance (1952–1956), and his manufacturing Vice-President, Ray Powers (1954–1956), that their East Grand Boulevard complex

Despite the problems of later versions, the transmission worked beautifully under the use conditions it was designed for. Packard's Gear-Start

In 1954, Ultramatic underwent a major upgrade to both the power transfer and hydraulic control components, which were reconfigured to give low gear starts automatically in the newly added "Drive" (D) range. Many
Packard owners had complained of lackluster acceleration with the earlier Ultramatics,

Ultramatic were being tested and designed by Packard from 1935 on,

Packard decided to offer a push-button gear selector for the 1956 series called "Touch Button Ultramatic". Mounted in a rectangular control pod at the end of a thick arm stemming from the right side of the steering column, the Touch Button Ultramatic gear selector used six buttons in two rows of

Packard's successful development of its own automatic transmission was unique, as no other independent automaker managed such a feat. The company's worsening financial situation, particularly after its merger with Studebaker, made keeping up with competitors' automatic transmission developments

The Twin-Ultramatic suffered many "teething problems" when introduced, which did significant damage to Packard's reputation for quality and reliability. However, over the years it's become clear that Packard's initial Twin Ultramatic problems were not out of line with any other new contemporary

The original Ultramatic did not switch automatically between high and low gearing ratios. The driver selected "high-range" or "low-range" ratios through the column shift lever. The intention was that in normal driving, the high (1:1) ratio would be selected at all times, and the two stage, dual

The system was electrically actuated, rather than Chrysler's very reliable mechanical pushbuttons, and was troublesome from the beginning. The electric shift motor, essentially a modified starter motor, proved insufficient to move the car out of Park on a steep hill, and would pop the circuit

In addition, small but important changes to shift linkages, better build quality, and stricter tolerances restored Packard levels of reliability to the 1956 transmission. Also new that year was an aluminum transmission casing, making the Ultramatic 90 lb (41 kg) lighter than its

After its first year, the Ultramatic Drive became available on all Packard models, and was immediately popular. It continued on, with a Packard program of modifications to improve reliability until 1954, although it was mostly trouble free from the start.

After World War II, Packard's range had contracted to variants of the mid-priced Clipper line. It was during this period that Packard began to suffer in competition with General Motors' Cadillac Division, thanks in part to their popular self-shifting

Finally, in mid 1949, Packard's 50th Anniversary, McFarland's Ultramatic Drive became available as a $ 199 option ($ 2,548 in 2023 dollars ). It was first offered only on the top-line Packard Customs, following in 1950 by the entire lineup.
