BMW Drivetrain Parts for BMW 3 Series E90 (2006-2011)

The ULTIMATE shifter upgrade for your BMW! Experience more precise throws, less shift lever travel, and an all-around transformation in your shifting experience.

For dozens of years, enthusiasts have critiqued the imprecise and vague feeling of BMW manual transmissions. Plagued with long throws, fore and aft play in gear, and a generally loose feeling, your OEM BMW shifter leaves much to be desired. While most standard carrier-mount short throw shifter kits will aid in reducing throw length and eliminating side-to-side play in gear, some enthusiasts long for a hardcore, race-inspired shifter that completely removes play and excessive throw length. At Turner Motorsport we share the same desire and set out to offer the ULTIMATE upgrade with this Performance Chassis Mount Short Shifter.

WHY UPGRADE?

Factory BMW shifter assemblies are complex by nature. The main component of this assembly is the shift carrier, a cast aluminum piece positioned inside the transmission tunnel that incorporates bushings at both ends for mounting. Like most factory parts, these bushings are designed to reduce NVH (noise, vibration, and harshness) transmission to the cabin. To the spirited driver, however, these bushings translate to flex and vagueness in the shift lever. Moreover, because this carrier is mounted to both the transmission and the body, the entire shifter assembly will "float" with the driveline, further increasing the vague and imprecise feeling of your shifter.

Our Performance Chassis Mount Short Shifter removes the shift carrier assembly entirely—removing any prospect of flex caused by bushings or driveline movement. By contrast, this chassis mount shifter offers a drastic reduction in shift lever travel, vagueness, and side-to-side play. An elevated base allows for moving the fulcrum point upwards, resulting in a much shorter and more precise throw. Shift times are further reduced by a tall, "rally style" shift lever, used to aid in leverage while also bringing the lever closer to the steering wheel. Our design incorporates a proprietary centering spring design, which is adjustable for increasing or decreasing self-centering force. In short, this design eliminates all the drawbacks of your factory BMW shifter, translating to more control, greater precision, shorter throws, and faster shift times.

FEATURES & BENEFITS

Reduced Throw: Modified shifter geometry and heightened fulcrum point translate to a shorter shift lever throw
Improved Shifter Feel: Eliminating the shift carrier and associated bushings drastically reduces "slop" and side-to-side play in the shift lever
Increased Precision: Mounting the shifter to the chassis allows for little to no variation in gear selection
Universal Fitment: Fits many BMW chassis with the provided base plate and hardware (see "Fits These Cars" for exact fitment information)
DESIGN

6061 aluminum, 4130 steel, and 316 stainless steel construction
A type-II black anodized finish
Adjustable self-centering spring
"Rally Style" shift lever

Ensure precise clutch installation with this specialized alignment tool, designed specifically for N54-equipped BMWs. While most aftermarket clutch kits include a generic alignment tool, many are intended for the N55, which is incompatible with the N54 due to differences in pilot bearing mounting and flywheel design.

This tool is engineered for both 6-bolt (01/2009+) and 8-bolt (-01/2009) N54 flywheels, allowing you to accurately center and align the clutch disc on the flywheel during pressure plate installation. Achieve a hassle-free and precise fit with this essential service tool.

Turner Motorsport Dual Shear Selector Rod (DSSR)

Enhance your N54-equipped 135i or 335i’s driving feel with the Turner Motorsport DSSR. Designed to give your shifter a much more precise and solid connection, this DSSR replaces the OEM selector rod, eliminating the play and deflection that come from single-shear designs. Pair it with a Turner short-shift kit for the ultimate shifting upgrade.

Think of the DSSR as a major upgrade from the single-contact OEM rod, much like riding a bike with two hands instead of one: you have stronger, more precise control over each gear change. With its dual-contact setup, the DSSR “sandwiches” both sides of the shifter and transmission, creating a direct link that feels solid, eliminating the vague and sloppy feel of the factory setup.

Key Benefits:

Enhanced Precision: Significantly reduces deflection and play, giving you a more connected feel while shifting Compatible with Factory & Aftermarket Shifters: Perfect for custom setups as well as stock configurations Durable Build: Fabricated from high-quality 303 stainless steel, offering rust resistance and longevity Complete Hardware Included: Comes with zinc-plated hardware for a secure installation Specifications:

Material: 303 stainless steel construction Compatibility: Replacement for part #25117524722 (E8X/E9X N54 models) Installation Design: Two-piece assembly with captive pins, designed for simple alignment and adjustability Fitment: Specially engineered to fit the tight N54 carrier without interference Installation Tips:

Remove your factory selector rod and take note of its orientation. Attach the DSSR to both the transmission selector joint and lower shift lever. Shift to 3rd or 5th gear for maximum access to the supplied hardware, then secure tightly.

Turner Motorsport Polyurethane Shifter Arm Bushing

Want more responsive and accurate shifts without sacrificing comfort? The Turner Motorsport Polyurethane Shifter Arm Bushing is the perfect enhancement to reduce unwanted movement and play in the shift arm assembly. Factory rubber bushings absorb vibrations for smoothness but compromise direct feedback and often wear out, leading to sloppy, imprecise shifting.

Crafted from high-performance polyurethane with a corrosion-resistant 304 stainless steel sleeve, this bushing maintains stability without stretching or wearing out like rubber. Experience the tactile feel of more precise shifts, with minimal NVH (Noise, Vibration, and Harshness) added to your drive. A must-have for any driver looking to take control of their BMW's performance.

Key Features:

Precision Control: Firmer than factory rubber for a crisp, responsive shifter feel Long-Lasting Materials: Made with durable 70a polyurethane and a 304 stainless steel mounting sleeve Easy Installation: Direct replacement—no modifications needed OEM Compatibility: Replaces BMW part numbers 25111222015 and 25111222652 Specifications:

Material: High-quality 70a polyurethane and 304 stainless steel Made in the USA: Proudly manufactured with quality materials Durability: Improved lifespan over factory rubber bushings, reducing slop and enhancing gear engagement

The transmission is sometimes neglected during regular vehicle maintenance over time. Without proper servicing, the automatic transmission fluid can deteriorate, resulting in contamination of the valve body and filter with deposits and sludge. This can cause issues like rough shifting, slipping, and, in severe cases, necessitate transmission replacement.

For a reliable replacement transmission filter, consider Febi-Bilstein for top-notch quality.
