It's a good thing I don't have the motor in yet as this would have been a real headache otherwise. The next hurdle is going to be the shift linkage. Add an Oil Groove to the Rear Output Shaft Support On the opposite side of the main transmission case, behind the sprag shown in the previous tip, resides the output shaft rear support. Or you can buy a valvebody reprogramming kit and tackle the job yourself. Again, no information, but likely a barrier to swapping the transmissions and the resultant carnage it could create. The output shaft has 25 splines. As you expect, piston, retainers, etc.
Pat Blais was working on this last time I talked to him about five or six years ago. Stalling for Speed: Be Realistic Next to a re-programmed valvebody, nothing transforms TorqueFlite performance more than a higher-stall torque converter. Differentiate between the model 833 A, B and E-body transmissions. Light duty 727s often have three clutches, our 1970 383 unit has the four-clutch pack used in heavy-duty and performance applications. The other important change at this point is the new for 1965 slip yoke on the propeller shaft replacing the ball and trunnion design. A reputable transmission man said this would make a difference and cause vibration. The base design from the original Torqueflite remains largely unchanged and the addition of a 2-speed output shaft overdrive unit that is bolted to the back of the 3-speed transmission has only two ratios: direct 1:1 and overdrive.
Forward direct clutch drum same as the A998 usually has a 4 friction disc pack - an A999 forward direct clutch drum with the 5 friction disc pack does interchange. For big blocks, the 400 is externally balanced as well, so it should have its own particular set of balance weights. Like a vehicle with a , a vehicle with a Torqueflite transmission starts out in first gear when the Drive or Second position is selected. This gear-set, which uses a welded-steel planet cage, is noisier and less durable than the original ratio gear-set with its machined-aluminum planet cage, but the lower first and second gear helped cope with the tall rear axle ratios needed for gas mileage. The slant 6 was released in 1960 and part of the new design was the use of the flexplate. There is no shortage of performance parts, and complete high-performance units are available from many suppliers. A-500 overdrive transmissions also have 26 splines.
In 1978, most Torqueflite transmissions gained a clutch to mechanically connect the converter's impeller and turbine, eliminating slip for better highway. Any input you may have would be appreciated via our. Key manual transmissions include the Chrysler and New Process three speeds, as well as the model 833 four speed. The Torqueflite 904 has 14 bolts with a rectangular-shaped pan with one corner on an angle. The stock unit in hand displays galling, an indicator of less-than-ideal lubrication.
This makes full use of the available bushing surface area for maximum converter hub support and control. The only lubrication comes from a single feed hole, so Ron chucks it into a lathe and cuts a 0. The small change in position causes the starter to hit the block on an EarlyHemi or Hemi-based Poly. Any known problems other than linkage mods using this in my A-body? The red friction plates are made by Alto. Why is a 727 called a 727 and a 904 called a 904? Also, with 523 lb-ft, the 3,000-stall speed is more of a suggestion.
And here is a kicker to boot. I actually dropped the transmission into my Duster, so I'm going by trial and error here. Part-throttle downshift functionality was extended to V8 A-904s in 1969, and to most A-727 transmissions in 1970 to 1971. I don't get into them myself. This will give you a better understanding of the relationship between some of the components of the car relating to matching numbers. Great photos and detailed instructions make it much less intimidating to start ripping apart your transmission for a rebuild.
Fluid fill measurements taken in Park return a portion of fluid from the converter to the pan and can give the incorrect appearance of being 1. The picture of the 727 transmission is first, the second is a 904 transmission — Gasket pictures to see what you may have from a bottom view 2. The 904 was originally called the Torqueflite 6 and the 727 was the Torqueflite 8. However, this was not always the case; the 1962 , a right-hand drive export model sold in and , used the U. American Motors and England's Jensen Interceptor also used the 727.
The first Torqueflites provided three speeds forward plus reverse. This transaxle would be upgraded in the 1980s into the A413 and A670 units, which were progressively heavier-duty, for Chrysler's and their derivatives, including the minivans. And there was a slant-six version of the 727 for truck use. This book is really well put together and extremely thorough, and definitely a must-have if you plan on taking on this kind of project. Always check the fluid level in Neutral.
While currently used with some internal changes such as the move from aluminum to steel planetary carriers and an increase in the number of clutch plates when coupled to the 5. I am hooking it up to the original 904 transmission. It is not wise to deviate from factory specs indicated in the appropriate factory service manual for your specific application. And make sure your dipstick assembly is correctly matched to the reality presented by your oil pan choice. Many different transmissions have been used on Chrysler vehicles, including those manufactured by Chrysler itself and others manufactured by outside corporations such as New Process.
Count the number of bolts and view the transmission pan shape on the automatic transmission. A whole lot of great info in there for sure. First, we need to differentiate between the pre-62 and post-62 transmission designs. Use Smooth Rear Drum Friction Plates for Better Holding Power The rear drum contains the forward clutch assembly and sees power loading in every gear except Reverse. This was used with Chrysler's 2. I'm going from column shift to floor shift, so I'm sure I'll run into some new challenges there.
