The 350 & 400 DO have a vacuum line that goes to the motor to operate the Vacuum Modulator on the trans.. But the 700r4 does NOT have a vacuum modulator. Shifts and line pressure are controlled by a TV (throttle Valve) cable that goes to your carb linkage, and MUST be properly installed/adjusted..Click to see full answer. Accordingly, does a 700r4 have a vacuum line?700’s don’t have a vacuum line. Like Extreme said it uses a t/v cable or detent cable. what makes a 700r4 shift? The TV cable on the 700R4 and 200-4R transmissions controls line pressure, shift points, shift feel, part throttle downshifts, and detent (full throttle) downshifts. This means the transmission will always have the correct oil pressure and shift feel regardless of engine torque. In this manner, can you run a 700r4 without a computer? Yes, the computer has no control over the transmission. It will shift just fine without a computer. You’ll need to pick another way to control the TCC though.What vehicles came with a 700r4 transmission?You usually do find the 700r4 transmission in GM cars like Chevy Blazer, Suburban, Camaro, Corvette, Impala and even in Oldsmobile Cars with a lot more.
