For 700-R4 & 200-4R Transmission

Are you tired of the trial and error method of adjusting your TV cable on your 700-R4 and 200-4R transmission? The crew at Bowler Performance Transmission sure was! That’s why they developed their own kit to solve this problem. When you purchase one of Bowler’s Tru-Shift systems you will get the easiest and best functioning TV cable adjusting system available. When you install this system you simply bolt on the supplied bracket and carburetor cam assembly, install the Bowler TV cable, then run the accelerator to wide open throttle. The cable will automatically adjust itself and you’re done. With this system there is no need to remove the carburetor, no cams to adjust, no need to drop the transmission pan, no need to install a pressure gauge to check the pressures and best of all – no more guessing. Bowler even includes different throttle cable brackets to cover Lokar, Gennie, GM square and early round hole. Each one attaches neatly to the supplied bracket. We have kits available for Holley, Edelbrock, FiTech TBI, Demon, MSD & Quickfuel Carburetors.

** We do not have anything for the Fitech LS Fuel Injection Intake **

**Please note that if you do have a FiTech we have a measurement you need to take to make sure it will fit – See the attached Image of how to measure your FiTech.**

** Sorry we do not have anything for Quadrajet, Rochester or any single or two barrel original style carbs **

Note: If you have a Quickfuel Carburetor, we will need to see pictures of the base and the cam. Please email us pictures at or call us at 618-943-4856.

    After dropping a few thousand on a new 700-R4, I was never happy with the way it was shifting. I was using the carburetor manufacturer’s correction kit, but it still just never seemed right. I was very concerned that I would burn out the clutches prematurely, and spent several frustrating hours adjusting the tension on the TV cable to no avail.

    I took to seek out a solution that would take the guesswork out and give me the peace of mind that I had installed everything correctly. The provided instructions and YouTube videos were great and made the installation a snap. It took longer to siphon the fluid out than it took to install the bracket and cable. As the instructions indicate, you just connect the cable to the bracket and gently move the throttle arm to WOT. The cable will ratchet itself out to the proper setting. Done and done.

    Now the TV cable has just the right amount of tension when idle, and the slightest movement of the throttle increases the line pressure immediately. My shifts are smoother and most importantly at the correct speeds and line pressure when making the way up the gears.

    The kit may seem expensive, but there is a cost associated with my own time and frustration trying to get a universal cable and bracket working.

    This is worth every penny, and I couldn’t be happier.

    Install everything yesterday and everything fit very nice and was very easy following the instructions given in the box, It was ordered to fit an Edelbrock carb and it fit perfect. We set the adjustment on the cable but won’t be firing the car off for at least two weeks.
