2003 Dodge Ram Pickup 1500 Transmission 4 & 5-Speed Automatic

2003 Dodge Ram Pickup 1500 Transmission 4 & 5-Speed Automatic The 2003 Dodge Ram 1500 comes with a choice of two different transmissions: a 4-speed automatic or a 5-speed automatic. Both of these transmissions are designed to work with the Pentastar V6 engine, and both offer excellent performance and fuel economy.

However, there are some differences between the two that may make one more appealing than the other for certain drivers. The 4-speed automatic transmission is the standard option on the base model Ram 1500, and it features an overdrive gear for improved fuel economy on the highway. It’s also a bit lighter than the 5-speed transmission, which can improve acceleration slightly.

The main downside to the 4-speed transmission is that it doesn’t offer as many gears to work with, so it can’t take full advantage of the engine’s power when accelerating from a stop or climbing hills. The 5-speed automatic transmission is optional on most trim levels of the Ram 1500, and it comes standard on the top-of-the-line Laramie model. This transmission has a wider ratio spread than the 4-speed, which gives it better low-end torque for quicker acceleration from a stop.

It also has an extra overdrive gear for even better fuel economy on long highway drives. The only real downside to this transmission is its weight; at nearly 100 pounds heavier than the 4-speed, it can negatively impact fuel economy and performance slightly.

This can be extremely dangerous, especially if it happens while you’re driving on the highway. There are a few different things that can cause these transmission problems. One is an electrical issue related to the speed sensor or throttle position sensor.

Another possibility is a software issue that prevents proper communication between the transmission and engine control module. And finally, there could be a mechanical problem with the clutch pack or valve body. DaimlerChrysler has issued a service bulletin about this problem and has extended the warranty on these parts to 7 years/100,000 miles (whichever comes first).

So if your truck is having any of these issues, be sure to take it to a dealer and have them check it out.
