You guys rock when I buy my new truck it won't even leave the dealership until a monster transmission is installed!!! And since Monster Transmission put a new transmission in there, it''s working a lot better. I will not go into much detail on these because they are very similar in design to stock 727s and 904s with the addition of a few control valves and a slightly different torque converter. Good overhaul gasket and seal kits are available from many different sources so check around. The lever at the lower right corner comes in different ratios, again depending on engine usage. Soften the Second-to-Drive Band Overlap The direct apply piston comes in various configurations depending on engine and vehicle type. How much transmission fluid does my transmission take? Band adjustment is a critical part of overall shift performance. This parking gear lever is pushed into the parking gear-governor assembly by a cam on the parking linkage.
Any increase in load-bearing surface area gets more power to the tires. However, this was not always the case; the 1962 , a right-hand drive export model sold in and , used the U. 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. I consider this to be the best modification, as far as high performance is concerned. Evolution of the Chrysler Torqueflite automatic transmissions Torqueflites first appeared in 1956, as an option in Imperials and 300Bs, with a cast iron body and an aluminum converter housing and tail shaft housing. The last row contains the Output Shaft, Governor Assembly and the Output Shaft Support Bearing.
In drive breakaway, the rear clutch is applied and line pressure is directed to various valves in the valve body. American Motors and England's Jensen Interceptor also used the 727. I have posted some articles about rebuilding resources on the front page. Certain items were altered in the 1965 model year: enlarging of the torque converter splines on some 1965 models, elimination of their flanged output shaft, and changing the shift mechanism from two cables to one rod-and-lever arrangement. The springs and valves work together to modulate fluid pressure to time application of the bands and clutches. On the inside of the front pump housing, the fresh bushing is staked in place to prevent grabbing and spinning. A whole lot of great info in there for sure.
Customer responsible for return shipping on core items. However, the shock of 4000 to 6000 rpm drops on the starting line created enormous loads on tires and driveline components. Roadbird, Anytime you have a job you need that manual for, let me know ill be more then happy to send it to you, keep it as long as needed. However, if the transmission is removed, a few more key items can be changed to give bullet proof operation. When you select the normal drive position, the transmission retains its firm, automatic shifts for the ease of driving you look for in an automatic transmission.
Torqueflite automatic transmission: major components by Tom Hand Courtesy of the with our most sincere thanks. The Mega Monster Transmission features: the latest technology in our industry with only the best internal components for increased strength, dependable performance and monster torque capacity. 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. They work well and they, too, are a good choice for everyday as well as some fleet use. I use Raybestos-Manhatten waffle-cut front clutch discs and Raybestos-Manhatten smooth rear clutch discs and Perfect Circle steel sealing rings. The channels in both valve body and transfer plate that resemble endless mazes, transfer fluid from valve to valve, or valve to case passageway. The performance on it is a lot better than it was before.
I''m happy with my truck. 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. For the higher horsepower applications the automatic transmission and converter combination is more often than not more durable and reliable than the clutch and standard gear box combination. Basic passenger cars have the three-pinion type seen here while muscle machines and most trucks have a more desirable four-pinion design. 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 output shaft, plug, and thrust washer could be retrofitted back to the 1974 model year, as a group. In the right half of this picture is the kickdown servo assembly, and the kickdown band. Torqueflite was an available option or standard equipment, depending on model and year, on all Chrysler products: , , , Chrysler and. One might think it wise to use the Hemi-band with the standard 727 drums, but it will not work because of the width difference between the four and five clutch drums. The overdrive will kick in at 47mph or whatever the eprom is set for in our electronics and turn back off at slower speeds without attention of the driver.
It became apparent that modifications should meet three important requirements: shift performance, longevity, and driver comfort. Because of this large number of threads and the fact that using the search option is unbeknownst to some members, I have put this together. Then place transmission into neutral, start engine, and quickly add transmission fluid until it reaches the full mark pan rail level on most applications on the dipstick. Rick Allison asks his customers to send their used bands back to him for re-lining. However, this is still very streetable and reliable 95% of my Torqueflites get these. The wider bushing could tolerate greater end play, so the cure was resolved that way by Chrysler.
This band could produce much greater holding power than the single width cast or flex band on most other 727s. Both of these fluids contain zinc which is the primary additive for proper lubrication for high performance transmissions. No cutting or grinding, two spots the size of quarters get smoothed in the tunnel and one spot the size of a quarter makes clearence for the right angle speedo drive. Advantages and Disadvantages The last sentence of the previous paragraph determines both the pros and cons of Torqueflite modifications. Here is a picture of what we are starting with: As you can see, we have removed it from the Scout and there is a lot of grease and grime on the unit. At the time, the rear-drive version of the TorqueFlite transmission had a non-electronic lockup.
