The extra gear is 3rd high range. We retained the stock 10-spring apply piston. He told me that he had been the owner of that Dodge Polara and had recently sold it; and, since I had repaired his transmission in 1969, he had not had any further issues. For 1966, the twin-cable shift and park control mechanism a holdover from the push-button operation was replaced by a solid shift control linkage consisting of a series of pushrods, rotating rods and levers. Inspection The final process before shipment is a complete inspection of the entire unit. Some higher performance 904 units were designated as 998s and 999s in the later 1970s. And make sure your dipstick assembly is correctly matched to the reality presented by your oil pan choice.
The swap may require some driveshaft tunnel modification on some cars. This basic transmission made it all the way into the 21st century, in the Neon series, after powering countless K-cars, L-cars, and other front-drive cars and minivans. The TorqueFlite was not just used by Chrysler; it was adopted by luxury automakers , , , Aston Martin, Maserati, and , as well as domestic rival and commercial-vehicle makers International Harvester, Land Rover, Iveco, Karrier, Matbro, Stonefield, Sirmac, Boss Motor, and Mitsubishi. Please refer to the core return instructions included with the part or contact customer service for more details. Available with this transmission are a variety of different styles of builds that provide a higher rating of torque and horsepower. This creates a sprinkler head effect and much improved oil flow.
Part-throttle downshift functionality was extended to V8 A-904s in 1969, and to most A-727 transmissions in 1970 to 1971. First, the rear clutch, used in all forward gears, is deactivated. You will have to fabricate a new crossmember using the old crossmember ends because the transmission mount is lower on a 518 transmission than a 727 transmission. Buyers warranty begins at original date of purchase and expires 3 years or 36 thousand miles thereafter. It is not wise to deviate from factory specs indicated in the appropriate factory service manual for your specific application.
I had no idea that they would consider upgrading to a wider front clutch retainer bushing, so the end play was my primary suggestion. During our inspection process, even the smallest of inconsistencies are addressed. It was used in Europe, on Talbot Simca, 1510 and Solara. The steps should mostly apply to any A-727 or A-904 Torqueflite transmission. We have carefully engineered a process that allows a 727 rebuild to maximize performance and durability while staying within a wholesale price range.
With bracket racing coming alive in the 1970s, it has been almost mandatory to have a good automatic in 90% of the classes if you want to be consistent and win races. When the sun gear and the front annulus gear spin at the same speed the planet carrier has to rotate at that speed gear train rules dictate that when two members of the same gear rotate at the same speed, the whole gear set rotates at that speed. Beware, the valvebody is a complex item and reworking is often beyond the skill set of the novice. This would prevent the front clutch retainer from wobbling on the reaction shaft support, especially with that narrow retainer bushing, causing wear to the front clutch retainer and the resulting front clutch failure. On the left, pens point out the wider bushing and load areas. Valid on orders shipped in the contiguous United States. Shifts are definitely firmer and some driver comfort will be sacrificed.
Inspect valves for burrs, springs for collapsed coils and bores for scratches. For a moment they fight. Bands- Just like the clutches, the bands are made from different materials. Hey Transmission Gurus, I need a little help identifying a 727 TorqueFlite Transmission. The problem lies in that the converter comes with 2 possible option of weights: butterfly and bars. Each lever has its ratio stamped on the side. The next row has the Oil Pump and the Front Clutch assembly shown.
When the clutch is spinning but not hydraulically operating, residual fluid can be forcing the piston out against the pressure plate front clutch or Belleville washer rear clutch , creating clutch drag. This addition required the removal of the torque converter drain plug. So it's definitely something you want. This smaller transmission used a 10 in 25 cm torque converter. The vent check ball in the piston must seat air tight and operate freely. Using this planetary only gives one turn to the output shaft for every 2. Ford quietly bought the rights to make a copycat, though it already had the rights to the Simpson gear-set, according to at least one contemporary automotive magazine.
The front wire is the overdrive ground and the rear wire is the torque converter lock-up ground. Rick Allison asks his customers to send their used bands back to him for re-lining. Can anyone tell me what I have? Then the front clutch is applied, which locks on to the front clutch hub-input shaft assembly. Therefore, through a couple of hydraulic tricks, line pressure is almost tripled to give the front clutch the necessary holding power. It was made standard, across the board, in 1981.
The case is in the upper left corner. To overcome this reluctance and to learn at the same time, I got a spare valve body from a salvage transmission and followed the Chrysler service manual in disassembly and reassembly procedures. The gated shift quadrants also permitted the deletion of the reverse safety blocker valve which, in TorqueFlites made through 1965, had shifted the transmission harmlessly into Neutral if the Reverse position were selected with the vehicle moving forward above approximately 3 mph 4. However, if the transmission is removed, a few more key items can be changed to give bullet proof operation. Introduction Of part one of this series has been read, it will probably be bringing up a few questions as to why a Torqueflite could be so well designed yet still need modifications. As the input shaft turns 2.
