Turbo 400 The Turbo Hydra-Matic 400 was introduced in the 1964 model year. In-exchange for Ford's 10-speed transmission, General Motors will let Ford use its 9-speed transmission for front-wheel drive applications; Ford ultimately declined use of the 9T. A relatively constant pressure was maintained by moving a slide inside the pump, which had the effect of changing the pump's displacement and therefore the volume of oil being delivered. I re assembled the left over parts carefully so we got the core charge back without hassles. What this did was transmit torque from the engine to the output shaft without any 'gear shifting'- all of the torque was transmitted by hydraulic means.
There are probably more 26 spline input, 32 spline output M20s in the world than any other Muncie 4-speed. Additionally, M22's are not all 26 spline inputs and 32 spline outputs. The 1957 trans is unique in that it also has a long extension housing tail shaft housing and a drain plug that the later trans do not. The adapter converts the thread to inverted flare for hard line usage. This circle is usually blank. Cone clutches have a high surface area-to-space relationship, and have been used in other automatic transmissions and even early 20th. Of course, that was many years ago.
You can see more details here:. From 1951 on, a cone clutch did the same thing when oil pressure was up, and a spring-loaded parking pawl was allowed to lock the same ring gear in the absence of oil pressure. Same with 2nd-over compared to 3rd. This was so that vehicles in their production run could begin using it without retooling any of the assembly processes. Do you know how to tell the difference between a Saginaw, a T10, and a Muncie four speed? The tranny i have bought a few weeks ago is in amazing good condition with no signs of wear at all.
The 4L60E came about as General Motors got into more complex computer controlled engines. Any other comments on for sure things to look at would be appreciated. The first turbine had 2. The basic design and operation theory of the gearbox changed little during that time, though several design upgrades and modifications were made during the total production run. First appeared in the mid to late 1960s with the Super Turbine 300. Even the Muncie has its limitations, but they are significantly higher than the Saginaw or Borg Warner. If you take a few moments to study the gear chart for your transmission and rear end ratio combination you will se why this product is so popular.
With this information what could cause these symptoms? Also, the reverse lever on the Muncie units is mounted in the extension housing, while the Saginaw reverse lever is mounted in the side cover Locate the serial number to differentiate 1969 and up Muncie transmissions. I hope you like the information and if you have any other questions, leave a question in the comment field at the bottom of the article, and I will answer your questions as soon as possible. Here is the main page on the. The car would then start to move, unless the transmission lever had been left in N, neutral. But in non-performance applications, they were still a good transmission.
There is one one shift table for the truck when it has no load, and another one for when it does. If you are feeling vibrations at all the time and not only on acceleration, you may have unbalanced tires. This is only possible through computer control. Some transmission has gone a lot of years without a transmission fluid change also, which can cause damages inside the transmission. This is a 4 speed, overdrive unit.
In first gear, power flow was through the forward planetary gear assembly either 1. Produced until the 2005 model year when the S-series was phased out. While the M21 and M22 did have the same gear ratios, the M22 did utilize a cluster gear with the gear teeth having different tooth angles. If the case, side cover, and tail housings are made solely of aluminum, well my friend, that would be a Muncie. It should look something like the item below, where I have circled M30 - which is the trans I have. This information was only useful to the Muncie plant by allowing the tracking of problem parts.
The only other pan that has 13 bolts is the Th-400. Right now it is shifting O. I'm the writer and the owner of this website. Identification begins by visually identifying the units as Saginaw, Muncie or Borg Warner models and then by differentiating the three Muncie units visually and by decoding the serial number. We are dedicated to giving you the technical support you need, when you need it! I had to do this on a 197? I do have the edelbrock correction lever coming for carb. A 2010 Hydra-Matic transmission Hydra-Matic was a complex design that was expensive to produce. So it's definitely something you want.
The following table outlines the differences between the Muncie models. They all have a variable pitch angle of incidence stator in the center of the torque converter that changes the torque multiplication when the angle is changed. However, if you are going to replace parts for your transmission, I do always recommend you to install new components and never install used parts if possible. Use a 26 spline input, hopefully with an oilseal and you could go 27 splines on the mainshaft if its a street car, but it will be stronger with 32 splines on the output. If you're not familiar with this, the first part of the video covers this and more. In the end, the true Hydramatic was rendered obsolete because of its cost, both in raw materials used as well as the machining needed.
