Transmission Shields and Scatter Shields

A transmission shield provides safety for the driver, track workers and spectators. SFI specification automatic transmission shields are required in many racing classes in order to pass technical inspection. These trans shields are also sometimes called transmission scatter shields which can be confusing. Blow proof bellhousings as used with manual transmissions were known as scatter shields for many years before protective shields for automatic transmissions arrived on the scene. 

In an automatic transmission equipped competition vehicle, the transmission shield covers the main area of the transmission where the bands, clutches and gears are located. A flexplate shield is often also required. This covers the area of the flexplate and torque converter. Click this link > flexplate shields to see our complete list of available flexplate safety items.

All of our transmission shields are certified as meeting SFI 4.1 specs and they meet or exceed the requirements of all major competition sanctioning bodies. We have models available to fit all popular automatic transmissions. All of our transmission shields are made from 6061-T6 aluminum. Each and every SFI rated part we sell has the most current possible date decal on them when shipped.

SFI 4.1 Transmission Shield Benefits

  • A properly installed transmission shield will provide greatly increased safety for driver, car and bystanders.
  • SFI 4.1 spec approved, required by many sanctioning bodies, in numerous classes, in order to pass technical inspection before being allowed to compete.
  • They look great and allow the transmission to run much cooler than the transmission blanket type safety device, because our shields allow for air circulation around the entire transmission..
  • Powder coated for great appearance, resistance to corrosion and ease of cleaning.

NOTE: For manual shift conversions or installations where the stock box over the selection shaft is removed and replaced by a switch on the shifter assembly itself.

Will not fit with stock electronics box in place over the shift selector shaft. You have to remove that stock box assembly over the shift selector and then the shield will fit. That box is the transmission range switch to tell the computer what gear the trans is in.

It does not mean that you have to use a manual shift transmission, but that box assembly over the shift selector shaft most be removed and a switch installed on the shifter itself. Then the switch on the shifter is used to take the place of the stock shift selector that you remove.

Frequently Asked Questions

Do you sell the CSR transmission shield?

No, we do not sell the 1 piece Kevlar CSR brand. We suggest you contact CSR directly if that is the type you want to use.

What is a scatter shield?

Some people use the term for what is more properly called a "blow proof bellhousing" on manual transmission equipped vehicles. It is also sometimes used to refer to the solid aluminum type of safety items as listed on this page which are made to wok on automatics.

Which is better a transmission blanket or shield?

We feel that a solid aluminum type shield is the better choice. It is far easier to clean, allows the trans to run cooler, and does not hold grease, oil and dirt the way that a blanket does.
