Unless it has been rebuilt with a fresh kit, recently. Keep It Cool, Heat is the Enemy The ideal fluid temperature is between 180 and 200 degrees. Since drains and level checks were not only unnecessary but frequently harmful through the introduction of more air, and seal-destroying dirt Chrysler eventually left off the tempting level inspection plugs. There is really no way to drain the converter. The pan may need the sealing surface straightened around the bolt holes. On the other hand, slowing the band application too much can lead to flare slippage.
One size does not fit all. I think type F would be the fluid most mopar people like on old torqueflites. Starting in 1990, it was used in some trucks and vans. This was used with Chrysler's 2. Automatic transmission fluids using lower quality base oil oxidized more easily than fluids using higher quality base oils. I believe in synthetics , just not sure on a 1970 transmission , but if you say it will not do damage , it's a go I'll ask my transmission guy , he's been in business for 35 years , but can't imagiine how syn fluid would be hard on seals , they said the same about syn motor oil back in the day , and i have never had a seal leak on very high mileage cars.
This model was used from 1939 through 1941 on Chrysler and 1941 Dodge models. The transmission gearbox used regular S. Torqueflite was an available option or standard equipment, depending on model and year, on all Chrysler products: , , , Chrysler and. The buttons were generally at the extreme driver's side end of the dash, i. Gear ratios: 1 2 3 4 R 2.
Ron is also a believer in synthetic automatic transmission fluid and says the old standard Type-F is outmoded today because it breaks down and foams more readily. This smaller transmission used a 10 in 25 cm torque converter. But fortunately the old six cylinder burned a lot of oil so I always had a gallon of bulk oil in the car. Any increase in load-bearing surface area gets more power to the tires. Jul 19, 2014 Basicly just remove the bolts in the transmission oil pan, make sure you have a drain pan under it and leave a couple bolts in, loosen the remining bolts and let the oil drain then loosen and remove them slowly as oil will be draining out while you are doing it. Stipdick on the Dakota says use +3. Its 510hp runs directly into a lightly modified 1963-vintage push-button 727 TorqueFlite packing three-pinion innards like these.
A revised Fluid Drive with a vacuum shifted 4-speed gearbox the M3 was offered on Chrysler and Desoto models for the 1941 and 1942 model years. I think it was Marv Ripes from A-1 Transmissions who actually recommended putting a quart of 10w-30 in torqueflights. What happens is the filter can plug, and drop fluid pressure, then the clutches slip and burn. The thick pan adds rigidity and acts like an engine crankcase girdle. Nov 21, 2010 The transmission is not sealed in the v8 I looked up.
When you drained the fluid, there was still a lot in the torque converter that didn't drain out. If the seal doesn't break on its own, gently tap it with a rubber hammer. Place a large drain pan beneath the transmission. The fluid coupling allowed the engine to stay running with the vehicle stopped and the transmission was still in gear. Oxygen reacts with high-temperature transmission fluid and can cause oxidation, rust, and corrosion. Band adjustment is a critical part of overall shift performance.
That has been the argument by most mechanics for years now , of course the engineers that design the stuff and run rigorous test , not just anecdotal evidence get my vote. They all have great heat reliability and longer life than the old fluids, plus have a better operational feel when shifting. You may want to consider having a lube shop, equiped with the T-Tech flush machine to do this job. If no license number is found, the fluid may not be Chrysler approved and the fluid cannot be guaranteed to meet Chrysler specifications. Chrysler, like many automobile manufacturers, uses transmissions sourced from other suppliers or transmission manufacturers around the world; these transmissions are not manufactured by Chrysler. Also, with 523 lb-ft, the 3,000-stall speed is more of a suggestion.
Different oils have different purposes. The clutch lining material may be factory or aftermarket. Type F is just what we used back then.

Today it's as simple as using the best available 'fossil-oils' and sometime, in right situation, synthetics. At least put one quart into the converter before install.
I grenaded a few 904's in my day , yours looks worse than any I blew up. So final check should be done with hot fluids and check for leaks. The license number should be shown on the container. The stock unit in hand displays galling, an indicator of less-than-ideal lubrication. This vitally important cast-aluminum item supports the rear drum. Stock front clutches have three or four friction-and-steel plate combinations but 426 Hemi transmissions have five—and a wider deeper drum to accept them. But the main point here is you really don't need to sweat it.
This transmission differed from the A904 by having a re-enforced case and internals. They told him that adding any other fluid than the Royal Purple would void his warranty with them. Personally, I don't think it really makes that much difference. Both of these fluids contain zinc which is the primary additive for proper lubrication for high performance transmissions. Powered by a 470hp 496-cube low-deck that makes 523 lb-ft, and packing 3.
