The typical total capacity for a full transmission fluid change on a 1999 Dodge Ram 1500 with the common automatic transmission is about 11–12 quarts. This includes the torque converter. Plan for roughly 5–7 quarts when draining the pan and another 5–7 quarts to reach the correct level after refilling, depending on the exact drivetrain.
In practice, the amount you add depends on whether you’re draining only the pan or also the torque converter, and on whether your truck uses the 46RE or the 47RE transmission. The pan itself holds approximately 5–7 quarts, while the total system capacity (including the torque converter) runs around 11–12 quarts. If you’re replacing the filter and performing a full change, you should expect to replace about 11–12 quarts of ATF in total. Always verify the exact figures for your specific setup and use the recommended ATF type for your transmission.
Why capacity varies across Ram 1500s
Two common automatic transmissions were used in 1999 Ram 1500 pickups: the 46RE and the 47RE. While their capacities are similar, the torque converter and internal lines can shift the total by a quart or two. The recommended ATF type can also differ by model year and transmission code. Check your owner’s manual or the transmission code tag under the hood to confirm the right fluid specification for your truck.
Typical capacity figures
Before listing the numbers, note that exact figures can vary by model and configuration. The following are typical estimates you can use for planning a full change:
- Total transmission fluid capacity (including torque converter): about 11–12 quarts.
- Pan capacity (drain-only): about 5–7 quarts.
- Refill amount after a pan drop (to bring level to spec): about 5–7 quarts, depending on the amount already in the torque converter and lines.
These figures are guidelines. If your Ram has a 46RE or a 47RE, the actual total can vary slightly. Always check the dipstick after warming the transmission to operating temperature to confirm the proper level.
How to perform a transmission fluid change
For a DIY transmission fluid change on a 1999 Ram 1500, follow a careful, step-by-step approach. The process typically involves warming the transmission, draining the pan, replacing the filter, reinstalling the pan, and gradually refilling while checking the level.
- Warm the vehicle so the fluid drains more completely, then safely lift and support the truck.
- Place a drain pan under the transmission pan, remove the pan bolts, and drain the fluid completely.
- Remove the pan, replace the old filter with a new one, and clean the magnetic plug if present.
- Install the pan with a new gasket, torque bolts to spec, and clean up any spills.
- Slowly add new ATF through the dipstick tube or fill port, starting with about 5–7 quarts, then run the engine and cycle through the gears to circulate fluid.
- With the transmission at operating temperature, recheck the level and add more as needed in small increments until it reaches the proper mark on the dipstick.
- Test drive the truck to ensure smooth shifting, then recheck the level again after the oil cools down, adjusting as necessary.
- Dispose of old ATF according to local regulations.
Note: Some older units may require attention to the torque converter drain, but many DIY changes do not drain the converter. Consult the shop manual for precise steps, torque specs, and the exact fluid specification (ATF type) for your transmission code.
Bottom line and practical tips
For a 1999 Dodge Ram 1500 with the standard automatic transmission, plan for about 11–12 quarts for a full change, including the torque converter. If you’re only draining the pan, expect around 5–7 quarts to be drained and similar amounts to be reintroduced to reach the proper level. Always use the ATF type recommended for your transmission, and verify the final level with a hot engine on level ground after cycles through the gears.
Summary
In short, a full transmission fluid change on a 1999 Dodge Ram 1500 typically requires about 11–12 quarts of ATF, with the pan drain yielding roughly 5–7 quarts. The exact amount can vary slightly depending on whether the torque converter is drained and which transmission code your truck uses (46RE or 47RE). Always confirm the correct fluid type and levels using the dipstick after the engine reaches operating temperature, and refer to the owner’s manual or service manual for model-specific guidance.
