It felt like a good quarter of an inch. The wider bushing could tolerate greater end play, so the cure was resolved that way by Chrysler. Thanks for the input The rocker shafts have a specific orientation. Is that thing set up for supercharging? I use Raybestos-Manhatten waffle-cut front clutch discs and Raybestos-Manhatten smooth rear clutch discs and Perfect Circle steel sealing rings. This transmission was very different, internally, from its iron-cased predecessor.
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. The word firmer is relative; the shifts are not severe in most cases this depends on kit manufacturer as well as intended usage , they are just more noticeable. Fortunately, Mopar Performance has the proper flex-plate for this application, which has both the proper attaching bolt holes and offset, eliminating the need for a transmission spacer. A couple of other advantages are: more fluid is supplied to various hydraulic units which sometimes compensates for seal leakage or wear; and certain kits give control of the 3-2 and 2-1 downshifts to the driver this comes in handy during hilly terrain. As in the other units, the 904 planetarys, output shaft, and governor assembly are similar to the 727 pieces, but smaller in size. Reasons for Modifications Stock Torqueflites, since the very beginning, have been very reliable. The shaft also has gear teeth cut into it to drive the speedometer gears.
There are reasons for this but they are not important to the overall explanation of the internal operations. The same problems i had before it was rebuild, i was hoping the rebuild was going to fix this. You can google search for Torqueflite shift improvement tips and see pictures on what I mentioned. Depending on gear selection, the sun gear-driving shell assembly will be driven by the front or rear clutch packs and will transmit torque to the rear planetary assembly. Here are pictures of 4x4 transmission 727 on the left and 999 on the right 3. The Torque Converter There has to be something to transfer motion from the engine to the transmission and that item is a Torque Converter.
Hopefully these roads dry up and can do some more testing, boooyahhh baby Any other thoughts on this stuff guys? Also, 65 and below were a pushbutton design: 9. The trans-brake uses an electric solenoid to actuate the reverse band while the shifter is in first gear, and once the button controlling the reverse solenoid is released the car almost instantly leaves the line. What are your guys guess on the horse power? How do i get that solid shift when im shifting at wot. There is one snap ring used to hold the governor body park pawl assembly secure on the splines on the output shaft. This particular servo piston is called a controlled load servo; it cushions the three-two downshift.
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. Introduction to the TorqueFlite The automatic transmission is a convenience item for most people. I will definitely be recommending them to friends and family. Probably due to the fact that 90% of vehicle owners believe a soft, slow shift is better on the transmission than a firm one, so original equipment units excluding factory high performance units are programmed for this shift. Should you modify your Torqueflite? It is fiber or bronze, depending on the year of the transmission. Any ideas on some mufflers that will make it quiet but hold up to the horsepower without taking away horsepower? The thrust washers prevent wear between the rotating members. Some time in 1969, the Service Manager told me that an almost new Dodge Polara was being brought in with transmission trouble.
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. Governor pressure will not be used in reverse, and a quick line pressure check shows reverse to have about 250 + or - 20 psi where normal line pressure is 75+ or - 19 psi. I asked around and was referred to Shifters by a couple people. Both the input shaft and the output shaft were heavily scored where the thrust washer rode between them. Street Smart Packages are not intended for all out race vehicles or for extended use above recommended horsepower ratings. Torqueflite Exploded View Before going into details of each subassembly in the Torqueflite, refer to the exploded view of a complete 1976-727 transmission.
In 1977, a low-slip torque converter, pictured above, increased the rea of the oil path from the impeller to the turbine and back by way of the stator by 20%, cutting friction while increasing torque capacity. Another questions i have is how do adjust my valves, i have 587 heads are those considered 360 heads? Using this planetary only gives one turn to the output shaft for every 2. The higher numbered levers multiply the apply force more to tighten the band quicker and harder around the front clutch retainer drum. He said i would need to speak to someone with knowledge of how the 1970 cars with 360 engines came. However, most of these modifications for competition and heavy duty service sometimes made the transmission too severe for everyday use. Once the planetaries are utilized, you get gear reduction and torque multiplication; or in other words, first or second gear depending on planetary usage.
It is not immediately obvious why reverse should be so high until the rear clutch and front clutch are compared. With the lever in second, the vehicle starts in low and shifts to second but line pressure blocks the 2-3 shift valve in the valve body to prevent any 2-3 upshift. These kits include transmission, torque convertor, dipstick, and transmission mount. I'll give my recommendations shortly. The Impeller and Turbine transfer fluid between each other to drive the Input Shaft of the transmission. Any one here updated the rear axles to get a bigger bolt pattern for bigger tires? When the shift lever is placed in drive, the rear clutch drive plates rotate the front annulus gear pinions which then spin the sun gear in a reverse direction. The governor signal is created by the rotation of the output shaft, which throws the governor weights outward and sets up the proper pressure I'll go into more of the pressure relationships in the modification section.
The reason I say unless something weird is going on is because it's possible it's manual body and they just plugged the linkage hole with the linkage and it isn't actually doing anything. Clearance is controlled by a selective thrust washer on the reaction shaft support, available in 3 thicknesses. The only thing left to spin is the rear annulus gear which is splined to the output shaft. Tod has put together plenty of 727s for us over the years, and his attention to detail ensures the transmission will operate to the limits of the parts inside it. Sometimes Chrysler owners complain of delayed motion of the vehicle after dropping it in gear from park. Often I or anyone for that matter asks to find out what type of transmission they have in their old mopar. Our cars have stiffer front sections of the springs and the traction bars are just dead weight.
