ATI Compu-Flow Valve Bodies provide the most accurate and efficient hydraulic controls possible for automatic transmissions. Years of research and testing have enabled ATI to design optimum oil circuitry for all popular transmission applications.

COMPU-FLOW STREET/STRIP VALVE BODIES While any of ATI's Compu-Flow Valve Bodies are "streetable", the Street/Strip Compu-Flow is the #1 choice. These valve bodies provide full automatic shifting if left in drive and manual shifting if low is selected. In either mode, the Street/Strip provides a firm, clean shift.

COMPU-FLOW REVERSE MANUAL VALVE BODIES Our Compu-Flow Reverse Manual Valve Body shifts opposite the OEM units away from neutral when up shifting (P-R-N-1-2-3). There is no automatic shifting. It will leave in the selected gear allowing street driven cars to move off in 2nd or 3rd 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; no engine breaking. (Note: All Turbo units freewheel in 2nd gear except #353400 for the T-350) This valve body is not recommended for the Powerglide since it must pass through low to get to neutral.

COMPU-FLOW FORWARD MANUAL VALVE BODIES The Forward Manual Compu-Flow is available with the same features as the reverse manual units, except for the standard OEM shift pattern (P-R-N-3-2-1). Engine braking is available in all gears. The Forward Valve Body provides a generally slower ET for drag racing since the band or clutches are on in low gear.

COMPU-FLOW REVERSE SAFETY TRANSBRAKES These valve bodies have all the same features of the highly successful ATI transbrake and they also have the added feature of reverse safety so that reverse cannot be selected accidentally or inadvertently. The vehicle will only engage reverse gear when reverse is selected and the transbrake solenoid is engaged.

COMPU-FLOW TRANSBRAKES Lock your race car on the starting line for hard, consistent launches. All Compu-Flow Transbrakes are reverse pattern, except for PG applications. These units are fully manual - no automatic shifting. The TH400 unit #403080 has a low draw - 1 amp - solenoids operating pilot circuits. On internal brakes, the solenoid is inside the trans. An ATI transbrake valve body is an excellent choice for bracket and delay box users.
