904 torqueflite
A Torqueflite 727 or 904
Just your regular dextron 3 fluid. Dextron III will work and is cheap. Type F is better, since more friction. Best is ATF+4 which is the current Chrysler fluid. I read that it is fully synthetic and has the most friction modifiers for faster, firmer shifts which saves your clutch plates. It is specified for the front-wheel drive Torqueflites (A-413, ...) which are almost identical inside to your 904 or 727 transmission (you didn't tell us).
904 is the transmission
The 727 and 904 transmissions are both automatic transmissions produced by Chrysler, but they differ in design and application. The 727 is a heavier-duty transmission, typically used in larger vehicles and capable of handling more torque, making it suitable for trucks and performance applications. In contrast, the 904 is lighter and designed for smaller, more fuel-efficient vehicles, featuring a simpler construction and lower torque capacity. Additionally, the 727 has a more complex fluid path and is often seen in higher-performance or heavy-duty contexts.
A while ago I ordered a transmission to replace the dying (later dead) one in my 1989 B250 van. I ordered the 727 assuming a big rig like that with a 318 would have the beefier transmission. My mistake, we had a van with a 904. The 727 is 4 inches longer than the 904, has a different size torque converter, and a different sized rear spline. a few bits of linkage is different. Now we have to go out and find a shorter drive shaft that properly connects to our new 727 and a new flex plate that fits the 727's torque converter size. We will probably have to modify some linkage as well. So I'd make sure to get the right transmission if you want an easy swap.
5 speed manual is either an AX5 or AX15 auto is a A-904
5 quarts, not including the torque converter. Both the Chilton's and Haynes for my '76 Aspen say the 904 holds 4 quarts. Chilton's says the Torque Converter holds 5, Haynes says 4. They BOTH recommend refilling with 1 quart less than capacity, running through the gears AFTER warming up the Engine and BEFORE driving the vehicle. Then check fluid level and add as necessary.
904 TF and 727 TF and many more with a kit.
Most likely it is a 904 automatic transmission. However, some 318's, especially in Chargers, were known to have come with a 727 Torqueflight as well, which is a far better transmission. You can tell which one you have by looking at the shape of the oil pan. The best bet is to have someone certified to work on Chrysler transmissions to look at it or you can do some research on the internet and determine which one you have by looking at pictures of the oil pan on the two transmissions. Hope this helps. --The Mopar Man
Should be an A727 tranny. I have an 1989 Dodge D100 3.9 v6 and the transmission in it is an 904 a lighter version of the 727.
Many choices here, either a 999, 904 an A 727 or an A 518
