About this product

Building a street-strip car behind a TH400, TH350 or 700R4, or a Ford C4 or C6, and want a ratchet shifter that stops in the right gear every time you pull it at full throttle? This is a pistol-grip ratchet floor shifter built to replace the 81052-style Magnum Grip Pro Stick. From the product photos it comes as a complete assembly: the shifter with its pistol-grip handle and trigger, the black cover, a red shift cable, mounting brackets and levers, and the bolts, clips and pins to install it. It measures about 8.23 in. long, 2.92 in. wide and 10.75 in. tall.

What a ratchet shifter does on a GM automatic

The shifter moves a cable that turns the manual shaft on the side of the transmission, and the manual valve inside the valve body decides which gear range you are in. A stock column or console shifter has a smooth gate you can overshoot. A ratchet shifter has a stop at every position, so a firm pull moves one gear and no further. That lets you shift a manual-valve-body car by hand without missing second and landing in neutral.

It can be set for a standard forward pattern or for reverse pattern, the setup used with a reverse-pattern manual valve body where you push forward to upshift. The shifter and the valve body must match.

Symptoms of a worn or misadjusted shifter

How to confirm before you buy

If you already have a ratchet shifter and the gears do not line up, check the cable adjustment and the bracket before replacing anything. On a 700R4, a gear range that feels wrong can also be a TV cable or valve body problem rather than the shifter; our 700R4 harsh shift guide and TV cable adjustment guide cover those, since a ratchet shifter does nothing for shift quality on its own.

Fitment

Listed for floor-shift setups on the GM TH350, TH400 and 700R4 (TH700) and the Ford C4 and C6, used with a 3-speed or 4-speed compatible gate. The original 81052 ships set for three-speed transmissions and its maker calls for a separate four-speed gate plate on a 700R4 or 2004R, so confirm the detent count on the gate before installing on a four-speed. Ford applications such as the AOD need their own install kits on the original as well. Browse the matching parts for your unit in our TH400, TH350 and 700R4 collections.

TH400 Ratchet Pistol-Grip Shifter Stick, 81052 Replacement: common questions

Is this a complete shifter or just the handle?

From the product photos it is a complete assembly: shifter mechanism with pistol-grip handle, cover, shift cable, mounting brackets, levers and installation hardware.

Will it work with my 700R4?

It is listed for the 700R4 (TH700) with a 4-speed compatible gate. Count the detents on the gate before installing; a 3-speed gate will not let you select every 700R4 range.

Can I run it with a reverse pattern valve body?

Yes. It can be set for standard or reverse pattern. Set the pattern to match the valve body before adjusting the cable.

Why does my car crank in gear after installing a shifter?

The cable is off by a detent or the neutral safety circuit is not set. Put the shifter and transmission in Park, readjust the cable and verify the engine only cranks in Park and Neutral.

Does a ratchet shifter make the transmission shift firmer?

No. It only controls which range is selected. Shift firmness on a 700R4 or TH400 comes from line pressure, the TV cable or modulator, and the valve body.
