This parking gear lever is pushed into the parking gear-governor assembly by a cam on the parking linkage. I've experimented with different types of products and they won't be named here. The reaction shaft has a bushing in it to support the input shaft which is part of the rear clutch assembly , oil pump assembly. There is not room here to cover all the details and other features like the automated 2nd-over passing gear so call the factory to discuss the full benefits demonstrated on these charts. This improves concentric stability and helps to better align all the moving parts. Finished off with a deep sump pan and complete dyno testing by Performance Automatic professionals.
Below it are the cooler line fittings, the shifter shaft seal, and neutral start switch. Upgraded 727 parts: Yes: Performance shift kit, valve body improver kit, and more. The representative asked me what I thought had caused the failure. Next we remove the front and rear clutch and the front band strut and band. Because the transmissions were shifted by , the transmission had a reverse blocker valve that shifted them into Neutral when drivers accidentally punched Reverse while moving forward.
In this picture you can see the front band. From top left you will see the Pan, the Case, and the Tail shaft, or Extension Housing and associated hardware. Should you modify your Torqueflite? These are inexpensive and easy to install. Moving to the top of the photo again, is the low-reverse lever assembly, its adjustment screw and lock nut, the reverse lever shaft and O-ring that the lever assembly pivots on and the rectangular strut that applies the low-reverse band. As gas mileage demands increased, thereby decreasing engine size, Chrysler changed from 727s to more 904-type transmissions G. Because the A-500 and A-518 were essentially made by adding and an overdrive planetary gearset to the A-999, gear ratios were not optimal; they were not redesigned to match the torque curve and torque rise of the mated engine.
Another disadvantage might be the price. The planetaries and sun gear in the top row give gear reductions and reversals; the output shaft transfers output torque; and the governor controls the shift points. These requirements brought the home mechanics and aftermarket manufacturers to some of these same conclusions; design and construction of transmission shift modification kits were needed. A clutch on the other hand, simply is along for the ride by connecting the engines power to drive-line. Part 1: Overview, and what each part does This is part one of a three part paper. But when the valvebody has been re-programmed, the specification called for by the kit maker supersedes O.
The stock drum explodes above 12,840 rpm. The last three pieces are contained in the low-reverse drum. I've never taken apart a trans by myself before so I'm a little hesitant. In 1989 and 1991, integral overdrives were added, resulting in the A-500 based on the A-904 and the A-518 based on the A-727 ; the engine computer controlled an electric overdrive unit built into the extension housing. Several manufacturers introduced shift improving kits. Reprogramming Kits Transgo manufactures three reprogramming kit for Torqueflites.
This does not come equipped with a new Speedometer Gear. According to Chrysler, the TorqueFlites did not need periodic band adjustments or fluid changes, but periodic fluid checks are a good idea with these transmissions being as old as they are now. There was also a smaller version of this transmission used in the cars made by Mitsubishi in Japan. I'll give the reasons that I modify Torqueflites and why the majority of 904s and 727s can benefit from a few well proven alterations. Rear Band Apply Servo Upgrade for Better First Gear Hold As good as the stock TorqueFlite is, the cast-aluminum rear band apply servo on right is known to fracture under stress. Drive Breakaway Drive breakaway or low gear is used to move the vehicle from a dead stop or very slow roll. It was used in trucks and vans starting in the mid-1990s.
It was used in Europe, on Talbot Simca, 1510 and Solara. Never apply full power in First gear during a burnout or toggle the gas pedal with the tires spinning in First gear on wet pavement. The Stator gives proper direction to the fluid flowing between the impeller and turbine. If you''re ever looking for a transmission, go to Monster Transmission, They''re Awesome. The Torque Converter There has to be something to transfer motion from the engine to the transmission and that item is a Torque Converter. In 1967 Chrysler changed to a 24-tooth design that takes a different torque converter.
Then remove the rear band. The 904 uses different kickdown bands to hold the front clutch retainer drum during second gear. Some valve body modification kits give complete control of the shifts to the driver. Then you remove the snap ring from the tail shaft and pull the governor off the shaft. The converter hub has slots that engage the tabs on the inner rotor of the oil pump to create oil pressure and oil flow from the pump while the engine is running. The deeper pan holds an extra three quarts of fluid, taking the total to 13 quarts with the 10-inch converter. My 727 is in need of a rebuild soon and I'm thinking about doing it myself for the expirience.
If you are not comfortable in undertaking any automotive repair, take your car to a qualified mechanic. Stalling for Speed: Be Realistic Next to a re-programmed valvebody, nothing transforms TorqueFlite performance more than a higher-stall torque converter. Chrysler Corporation licensed this gearset from Simpson in 1955. The other was that the front clutch retainer bushing was too narrow, and I suggested it be widened. Servos and Bands Shown in this photo are the bands necessary to give second gear kickdown band , and reverse or manual low low-reverse band. A whole lot of great info in there for sure. There is no snap ring to remove.
