The convertor needs to match the camshaft and gearing of the car. The shaft also has gear teeth cut into it to drive the speedometer gears. Prices of kits and recommended usage will he discussed. Plus, there is also in the back a resource guide on the Chrysler Torqueflite Transmission numbers for each car or truck. Hope this helps,later plmczy I've had both, and always had better luck with the 904, believe it or not! These kits include transmission, torque convertor, dipstick, and transmission mount. Once Bluefire Reader is installed and activated with Adobe you may download eBooks directly on your device using the download links provided on the confirmation page of your order, the confirmation email or in your Are eBooks returnable? This is due to the converter not being fully charged in park. Remember, our stated goal is a 150-mph capability, so we will maintain the ultra-high 2.
Are you having problems fixing a A904 transmission? I was building for 520hp but you won't be seeing anything near that from a 318 so you can probably get away with just a real good rebuild kit. Below it are the cooler line fittings, the shifter shaft seal, and neutral start switch. Many thanks to David Frey, Vicki Milley, Debbie Hoflo, and a very special thank you to Tom Mallot for his photographic help. We upgraded our servos with a set of billet servos from our local Transtar transmission component supplier. 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. Rated to handle up to 750 horsepower. Therefore, putting it together, taking it apart or starting from scratch can be found right inside.
Reprogramming Kits Transgo manufactures three reprogramming kit for Torqueflites. While these modern equivalents are impressive, many of these transmissions are based on decades-old designs. Probably better than half of all failures involving Chrysler automatics in performance useage can be traced back to a cheap or faulty converter! Hello everyone, I am in need of some answers. The guy that rebuilt it upgraded it with the heavier duty parts that the 904s in V8 cars use. Should you modify your Torqueflite? In Mopar circles, they have become synonymous with strength, durability, and performance.
Alot of hot 340's used these 904's and they seemed to work fine. This is a good kit for motor homes, taxis, and police vehicles; good shifts, firm, yet comfortable B. Because of the skill and generosity of a close friend, I'm able to supply a block diagram of the Torqueflite in the various gears. I can honestly say the only problem I ever had with a 904 was converter related, and that happened to two different 904s. If you are interested in more detail than I have given, get the.
With use, these see a lot of heat and eventually they warp and glaze over. In park, the driveline will be locked as explained above. Use it to download and purchase digital content, which can be read both online and offline. In 2003, he began writing tech articles for magazines, and has been working as an automotive journalist ever since. Like was said earlier more drag guy's are using the 904 because they are lighter and have less rotating mass to over come.
Both the input shaft and the output shaft were heavily scored where the thrust washer rode between them. You practically learn so much even if for being a beginner or not knowing what to do, it's all covered inside. As in any repair situation, a person should refer to the appropriate Chrysler service manual for exact details and adjustments of particular units. When the governor signal moves the 2-3 shift valve, fluid is applied to the release side of the front servo and the front clutch is applied. Part three give some of the techniques that can be used to troubleshoot Torqueflite irregularities that I've seen most often. With the low-reverse band holding the rear planet carrier stationary, torque is transmitted only through the planet pinions via the sun gear , driving them in a reverse direction. My '56 F-100 project is getting a Blown 331 Hemi for power.
However, this is still very streetable and reliable 95% of my Torqueflites get these. I run a 904 in my slant 6 Dart drag car. Looking at this in order, it happens like this: The front clutch is appliedm transferring engine torque through the sun gear driving shell, driving the sun gear in the same direction as the engine. However, the shock of 4000 to 6000 rpm drops on the starting line created enormous loads on tires and driveline components. If you have the option, pick up a set of these, they are better.
This, as well as lots of overlap, and a propensity for freewheeling in reverse until the car was good and ready to move, told us it was definitely time for a rebuild. One type is called a double wrap band, similar to the Hemi kickdown band; it is used with the V8 engines to give greater low-reverse drum holding capability. I am not going to describe each valve or spring just yet. The other type of servo assembly does not use an internal spring-piston assembly, and is usually found in high performance applications where soft shifts would be detrimental. I'll go through a gear by gear description explaining the active components and how they combine to get the different gears.
