It was simple, reliable, dependable, quiet, efficient, economical, and gave Chrysler cars a performance advantage. Lowering the pressure helped keep the seals from leaking or wear; a regulator valve added pressure when needed. So I started wondering about the tranny. For 1964, the canister filter was eliminated, and the transmission's internal intake screen was replaced by an efficient filter. All Torqueflites had the same internal ratios, until, starting in 1980, a wide-ratio gearset was created for most of the 998 and 999 transmissions 2. The factory only put A999's behind the 360 engine. Besides just simply draining the transmission oil pan, the cooler lines and the transmission cooler should be power-flushed.
However, this was not always the case; the 1962 , a right-hand drive export model sold in and , used the U. All the front-drive transaxles on non-turbo engines except for one used with the 2. This smaller transmission used a 10 inches 250 mm torque converter. This feature permitted the transmission to shift from third to second gear in response to moderate accelerator pressure. Then, for the 1966 model year, engineers changed the transmissions to be shifted by a single-rod linkage; and, since it was harder to accidentally go into Reverse while moving forward, they dropped the reverse blocker valve. The 1955 Packard had been the first car with a part-throttle kickdown.
Rated stall is 3,000—3,400 rpm in a typical small-block, but 3,400—3,600 rpm in a big-block. Inspection, Checked for: Leaks Shifting Difficulties Vibrations Excessive Noise Temperature and Performance Gear Ratios: 2. Any part that does not meet our strict guidelines will be completely disassembled and gone through until our quality requirements have been restored. Converting Torque Project Stealth Bomber has some unique requirements in the torque converter department. The A727 incorporated a parking pawl and various internal improvements, and used a 10. This change was made to maintain acceptable in-town performance with taller final-drive ratios in the rear axle — 2. TorqueFlite was introduced on the heels of the company's two-speed automatic, which made its debut in 1954.
The rear pump was eliminated, which simplified and cost-reduced the transmission but rendered push-starting impossible; Chrysler engineers reasoned that improved electrical and fuel systems reduced the need to push-start vehicles, and safety concerns weighed against doing so. It was equipped with five direct friction plates. Too loose, and it slips. Early A-727s had dual pumps, but for the 1966 cars and trucks, they dropped the rear pump, probably to reduce costs. The first TorqueFlite automatic transmission was the A-488, launched in the 1956 Imperial. There was not enough money to modify the gears; I was told that the 80th percentile average driver would not notice the difference. Certified Every remanufactured transmission has been built and inspected by a certified technician.
The 4-speed electronic 4-speed automatic transaxle would eventually replace it, but the 3-speed lasted for more than a decade after the 1989 debut of the 4-speed unit. This is in contrast to vehicles with several automatics from and , which start out in second rather than first if the Second position is selected. I did a couple of downshifts at the stop light and manually shifted from first to second to third, not having to take the rpm up high at all, and it flushed the junk out. Button arrangement varied by vehicle model and year; sequence was Reverse, Neutral, Drive, Second, and First, from top to bottom with vertically arrayed buttons, from left to right with horizontally arrayed buttons, and clockwise starting at upper left with clustered buttons. Many 1978 rear drive cars also had a major new addition: , which used a mechanical lock instead of the usual fluid interface in the torque converter. The A904 has 3 clutches in both the front and rear drum.
Call Mon-Fri 9-5 Central 1-888-995-7278 Dyno-Tested Every transmission has been run on a state of the art Dyno. Give Your A999 Transmission The Proper Care It Deserves Posted by on Monday, September 30th, 2013 The A999 is a three speed automatic transmission made by Chrysler. Like a vehicle with a , a vehicle with a Torqueflite transmission starts out in first gear when the Drive or Second position is selected. Successors to the TorqueFlite by Bob Sheaves The A500 and A518 were developed from the A-999 — which had been created as a cross between the A-904 and the famed A-727. The transmission fluid and filter should be changed every 30,000 miles, regardless if Chrysler says you can go longer in between oil changes. Part-throttle downshift functionality was extended to V8 A-904s in 1969, and to most A-727 transmissions in 1970 to 1971. The buttons were replaced by conventional steering column- or floor-mounted shift levers in all automatic Chrysler-built vehicles for the 1965 model year, though floor levers were available in certain sporty 1964 models.
The output shaft, plug, and thrust washer could be retrofitted back to the 1974 model year, as a group. In 1978, most Torqueflite transmissions gained a clutch to mechanically connect the converter's impeller and turbine, eliminating slip for better highway. I highly recommend doing so with a over one that was simply rebuilt, or a used one. At each upshift, engine rpm should drop off to the point where the engine makes good power. In 1978, most Torqueflite transmissions gained a clutch to mechanically connect the converter's impeller and turbine, eliminating slip for better highway.
For the most part, this was proven to be true. We started blowing up details to get a closer look at the valve body, the rear planetary gear set, the stator and the flexible drive plate. This was a major boon for drivers, making the powertrain more responsive to sudden demands for more but not full-throttle power. Slow to get a fully automatic transmission on the market, Chrysler wasted no time in getting past its two speed. During our inspection process, even the smallest of inconsistencies are addressed.
