The Ford E4OD transmission was designed to fit behind various powerplants including gas and diesel engines. Most failures revolve around the torque of the diesel motor, especially when power is increased over stock. The good news is that the framework of the E4OD allows for substantial increases in reliability and capability. ATS E4ODs

Features:

  • ATS Five Star Torque Converter featuring a billet cover, five lock-up clutches, available in either low or high stall configurations
  • ATS billet input shaft
  • ATS Commander Lock-Up Controller
  • ATS billet flex plate
  • High performance overdrive, intermediate and forward clutch packs, with one additional clutch added per section
  • Modified transmission pump to increase line pressure, which provides increased clamping force on the clutch packs
  • Modified valve body that focuses around precise shifts, increase line pressure and increasing the torque capacity of the E4OD
  • New bearings, seals and gaskets
  • New low roller clutch, heavy duty intermediate sprag, bonded coast and overdrive pistons

ATS Deep Transmission Pan which adds 5 quarts of fluid over stock, which helps keep the transmission cool

The Stage 4 package includes a billet input shaft for increased reliability when towing heavy loads, under modified power levels or street performance. The billet input shaft is designed to withstand greater torsional loads than the factory shaft, thus increasing reliability.

The shaft is made of billet 300M material and precisely machined for an exact fit. In addition, we add a lock-up controller for the torque converter on the Stage 4 setup. This allows the user to base lock-up on vehicle speed in any forward gear. This provides several benefits, including increased fuel economy, lower transmission operating temperatures and more power to the ground, at a lower speed. This feature becomes useful in towing situations and performance applications where power at low rpms is desired. For those trucks with an exhaust brake, the controller will synchronize torque converter lock-up with the brake.

This will allow the converter to stay locked on deceleration to increase braking force. The Stage 4 features the addition of a billet flex plate. The billet flex plate is designed for high horsepower/torque trucks and those that tow heavy. The flex plate is the first point of power transfer from the motor to the transmission assembly. By using a billet steel flex plate, we can increase the reliability of power transfer from the crank to the converter.

The ATS Stage 4 Package is designed for trucks that are used for light/moderate/heavy towing, greater-than-stock power levels and racing/street performance. The transmission package comes with a 5 year / 500,000 mile warranty.

Extremely comfortable, leather sole. Hard to find a style.
Size: 13.5-14.5 Women/12-13 Men, Color: Navy Blue, Size: 13.5-14.5 Women/12-13 Men, Color: Navy Blue
Totally worth the price. This type of style is very hard to find, my husband had another pair a few years ago that he was never able to replace. These fit his wide feet and are very comfortable. The elastic at the ankle is not too tight. So glad I was able to find him a replacement. We bought the blue in a size 12. Love the fact that they are washable.

Very comfortable Slippers. Great buy!
Size: 12-13 Women/10.5-11.5 Men, Color: Charcoal
I bought these to replace a pair of slippers that I have had for years that are very similar to the slippers I bought, but I had worn a hole in the leather on mine, so I had to find something new and similar. These slippers are worth the money they are very comfortable, and I am sure they will last for years. They are a little tight around the ankle cuff but they are still new and I am sure they will wear in a little more when I start wearing them more.

Great slippers but disappointing quality.
Size: 7.5-8.5 Women/6-7 Men, Color: Ash, Size: 7.5-8.5 Women/6-7 Men, Color: Ash
Extremely comfortable, attractive slippers but the stitching came loose on both leather trim areas almost immediately. I tried to sew/glue down the stitching (as seen in photo) but it kept unraveling. Disappointing as these slippers are great in every other way (though they do run a bit big...I wear a 9 but ended up with a 7.5-8.5 which fits with a bit of room to spare even with thick socks). I just hope they hold up after my latest attempt to stop the thread from pulling out any more as I do really love wearing them. Perhaps I just got a bum pair?

Quality and comfort
Size: 10.5-11.5 Women/9-10 Men, Color: Black
Comfortable and fit well. I got these to replace a very old pair that finally wore out! Warmth is medium (I wear puffer booties for when it's really cold). Quality on these is great!
