ATI Compu-Flow reverse manual valve bodies shift opposite of the OEM units, away from neutral when up-shifting (P-R-N-1-2-3). There is no automatic shifting. They will remain in the selected gear, allowing street-driven cars to move off in 2nd or 3rd gear in slippery conditions. The governor and related components are eliminated, as well as throttle pressure, cables/vacuum lines, and linkages. All units freewheel if you lift in low gear; there is no engine breaking. (Note--all turbo units freewheel in 2nd gear, except #353400 for the T-350.) These valves are not recommended for the Powerglide, since it must pass through low to get to neutral.
