What This Product Does
This internal transmission component forms part of the first and reverse gear engagement mechanism. Working with the gearbox synchroniser, selector and associated hub components, it helps transfer selector movement so that first or reverse gear can be engaged correctly.
Functions
- Supports engagement of first and reverse gears
- Transfers movement through the gearbox selection mechanism
- Works with the synchroniser and related engagement components
- Maintains the correct relationship between the selector and gear assembly
Technical Details
- Brand: OE Match
- Part type: shifting gear and outer hub
- Gear application: first gear and reverse
- Primary reference: 91130222602
- Related reference: 91130222600
- Transmission application: Porsche 901-type manual gearbox where specified
Symptoms of Fault
- Difficulty selecting first or reverse gear
- Notchy, stiff or inconsistent engagement
- Grinding or crunching during selection
- Gear disengaging unexpectedly under load
- Visible wear or rounding of the engagement surfaces during inspection
- Excessive play within the associated hub and selector assembly
Why Replacement Matters
A worn shifting gear can affect engagement and place additional load on the synchroniser, selector and adjoining transmission components. Replacement is normally undertaken as part of a gearbox repair or rebuild after the assembly has been dismantled and inspected. OE Match components are intended to provide an alternative that follows the original application and fitment requirements. The surrounding synchroniser ring, operating sleeve, selector parts and bearings should also be checked for wear before reassembly.
FAQs
- Is this part used for both first and reverse?
Yes. It is specified for the first and reverse gear engagement assembly. - Does it fit every early Porsche 911 gearbox?
No. The supplied application is for Porsche 911 models from 1965–71 with the 901 gearbox. Confirm the transmission type and reference number before fitting. - Is this suitable for the Porsche 914-6?
Yes, the supplied fitment includes Porsche 914 and 914-6 models from 1970–76. - Should other gearbox components be inspected?
Yes. Synchroniser parts, selector components, bearings and mating engagement surfaces should be examined during the rebuild. - Can this be installed without dismantling the gearbox?
No. Installation requires transmission disassembly and correct internal setup, so the work should be completed by someone experienced with Porsche manual gearboxes.

OEMatch Operating Sleeve / Slider and Parts — Engagement, Smoothness, Control
Operating sleeves, sliders and associated parts restore precise gear engagement and reduce shift noise and wear in Porsche manual transmissions. These items suit gearbox rebuilds, restorations and higher-load applications where accurate engagement and consistent operation are required.
Available Types
- Operating sleeves (shift sleeves) for common Porsche gearboxes
- Sliders and selector forks
- Associated rebuild items such as synchro rings and dog teeth
Understanding OEMatch Operating Sleeve / Slider and Parts
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original operating sleeves and sliders.
OE (Original Equipment) refers to parts matching original specifications for the operating sleeves and sliders and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM operating sleeves and sliders engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Operating sleeves and sliders transfer selector movement to the synchro hub and dog teeth, allowing one gear to disengage while another engages. They work alongside synchro rings to equalise rotational speeds and help avoid grinding; correct geometry and surface condition are important for smooth, repeatable shifting.
Benefits Include
- Restores smooth, accurate gear changes and reduces grinding
- Limits additional wear to synchros and gear teeth during engagement
- Supports consistent shift feel after a rebuild or repair
Why Operating Sleeve / Slider and Parts Wear and Fail
- Gradual wear of engagement teeth and sliding surfaces from repeated shifting
- Poor lubrication or contaminated lubricant increasing friction and fatigue
- Misalignment, worn synchros or excessive heat during high‑load use
The Importance of Replacing with OEMatch Operating Sleeve / Slider and Parts
Timely replacement of worn sleeves and sliders restores reliable gear selection and helps prevent secondary damage inside the gearbox. When rebuilding a transmission, renewing these parts together with synchro rings and related items reduces the risk of premature wear and improves long‑term operation for Porsche models.
Advantages
- Precision machining and hardened materials to resist wear
- Dimensional accuracy to support correct alignment and engagement
- Suitable for road, restoration and higher‑load applications
Support & Advice
Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified. If you are unsure about setup, slider condition or backlash settings, consult a specialist with Porsche experience.
