K-Series Select Springs: How to Swap Them for Better Shift Feel

Swapping the select springs in your K-series transmission is a cheap way to sharpen shifter centering. Here's the step-by-step process, plus the mistakes to avoid.

Quick answer

Replace the select springs inside the transmission with higher-rate springs, like the K-Series Transmission Performance Select Springs, to increase centering force and make the shifter return to neutral more crisply. The job is straightforward but requires care to avoid losing the springs or over-stressing the detent mechanism.

What select springs do and why upgrading changes feel

Select springs are the small springs inside the transmission that push against the select mechanism, helping the shifter center itself when in neutral. Honda calls them the First-2nd Select Spring and Fifth-Sixth Select Spring. Over time, the original springs can lose tension, and the shifter may feel vague or slow to return to center. Installing higher-rate springs increases the centering force, giving a more positive, snappy feel. The K-Series Transmission Performance Select Springs are a direct replacement that increases spring force by approximately 50% and features a black-oxide coating for better oil retention. They are a simple upgrade that sharpens shift feel without changing the shifter itself.

When to choose this upgrade and when to skip it

This upgrade is ideal if you want a more precise, mechanical shift feel and quicker centering from neutral. It pairs well with other shifter upgrades like base bushings or a short shifter. However, if you already find the shifter too stiff or you prefer a light effort, the increased spring rate may feel tiring. Also, if your transmission has other issues like worn synchros or a damaged select mechanism, springs alone won't fix them. Inspect the mechanism before installing.

Step-by-step select spring install

1. Gather tools and parts: You'll need the new select springs, a socket set, pliers or pick tools, a torque wrench, and replacement fluid if needed. Work on a lift or jack stands for safe access. Common mistake: skipping the torque wrench—these fasteners need proper torque to avoid damage. Double-check that you have the correct springs for your transmission code (e.g., K20 vs K24) before starting.
2. Locate the select spring covers: On the transmission, find the select spring retaining bolts—typically two covers on the side of the gearbox. Clean the area around them to prevent dirt from falling in. Common mistake: confusing them with detent bolts; consult a service manual for your specific model. Take a photo before disassembly to reference bolt locations.
3. Remove the old springs: Carefully unscrew the retaining bolts and extract the old springs and any shims. Keep track of the order and orientation. Common mistake: losing the springs inside the transmission—use a magnetic pick tool and work over a tray. Inspect the old springs for wear; if broken, check for debris in the bore.
4. Install the new springs: Insert the new select springs into the bores, ensuring they seat flat. Reinstall any shims in the original order. Common mistake: over-tightening the retaining bolts, which can crush the springs or strip threads—follow the service manual torque spec. Lubricate the springs with clean transmission fluid before installation for smooth operation.
5. Check shifter feel and top off fluid: Reconnect the shifter linkage, then row through the gears with the engine off to confirm centering. If the feel is too stiff, recheck spring orientation. Top off transmission fluid if any was lost. Common mistake: forgetting to refill fluid—check level and fill as needed. Test drive gently at first, listening for any unusual noises from the transmission.

Product facts

K-Series Transmission Performance Select Springs: Increases shifter centering force by approximately 50% and is black-oxide coated for better oil retention. The higher rate gives a snappier return to neutral, while the coating helps the springs stay lubricated and resist corrosion inside the transmission.
