Keep Your Ford Van E40D Transmission Running Strong

Posted by on Friday, November 28th, 2014

The E40D is a 4-speed automatic overdrive transmission built by the Ford Motor Company. It is heavily based on the C6 3-speed transmission, and is Ford’s first attempt at building an electronically controlled automatic transmission. Both transmissions are considered to be heavy duty in design. The C6 transmission has a first gear ratio of 2.71:1 and an overdrive ratio of 0.71:1 (29% over driven). The 4E0D transmission was designed to help Ford vehicles meet the more restrictive CAFE corporate fuel mileage laws. It was first put into use in 1989 and remained an optional transmission through the end of the 1998 model year, when it was finally replaced by the 4R100 transmission. The E40D could be found in a number of Ford vehicles, including the Ford Bronco, the Ford Expedition and the Ford F-series pickup trucks. It could also be found in the Ford E-series vans.

The E40D could be found in the fourth generation of the E-series van, which was produced between 1992 and 2007. The “E” stands for Econoline. Your choice of engine in this van included a straight six engine, a 302 cubic inch and 351 cubic inch small block, a 460 cubic inch big block, a 7.3-liter diesel engine, and a 413 cubic inch V10 engine. One also had a choice of regular or extended bodies. With all the choices available, these vans made great delivery vehicles.

Automotive parts stores, flower shops, and painters all used these vans. The one thing all these companies share in common is they rely 100% on these vans to run flawlessly every day, or they risk going out of business. Here are a few things you can do to keep the E40D transmission in your Ford delivery van running strong.

Get the transmission fluid changed often. With the natural stop-and-go use of these vehicles, it’s especially important that you get the fluid changed sooner rather than later. While Ford may recommend that you can go more miles between oil changes, we recommend that you have the fluid changed every 20,000 miles. It’s also a good idea to switch over to a synthetic transmission fluid at this time. Synthetic fluids tend to last longer before breaking down, and they are more resilient to high, damaging transmission temperatures.

Every time you get the transmission fluid changed, you should have the transmission filter replaced too. Be sure to use a high-quality replacement filter. Cheaper filters tend to not collect the fine particles that end up damaging your E40D transmission. Cheaper filters can also crack, allowing the fluid to completely bypass the filtering process.

Every time you bring your vehicle in for a fluid change, you should also have your transmission bands adjusted. Unlike the clutches found in your C6 transmission, the E40D bands do not self-adjust. A simple 5-minute adjustment will keep the bands from eventually slipping.
