- Alto High Performance Steel Module
- Overhaul Kit
- New Filter
The 4R100 transmission replaced the E40D transmission for the 1999 year model and was mated to the 7.3L Power Stroke diesel through the 2003 model year Ford trucks. The 4R100 proved to be a fairly reliable transmission in stock performance levels, however once power adders are introduced the transmission, becomes the weak link in the drivetrain.
This electronically controlled overdriven unit boast a first gear ratio of 2.71:1 and a second of 1.54:1, which makes it great for towing and hauling with an .71, overdrive fuel economy is also improved.
The Clutch Kit
This new 4R100 rebuild kit includes Alto Red Eagle clutches along with Kolene steels.
Red Eagle Friction is the go-to material for most performance applications. The lining has a unique dual-saturation, which imparts high friction coefficients and high heat resistance. Red Eagle clutches are designed to limit the amount of "slip" by providing a shorter lock-up time, generating less heat.
The proprietary process starts with the friction paper saturated in a phenolic resin, cured, and then saturated a second time in a silicate. The silicate imparts high heat resistance.
Red Eagle clutches:
- Are designed with a softer, more resilient base paper.
- Assure less wear against opposing steel plates.
- Reduce the incidence of steel plates burning and warping.
