What This Product Does

The stop plate forms part of the mechanism at the gear lever, providing a stop surface that helps define lever movement. It is a gearshift control component rather than an internal gearbox part, and should be assessed alongside the surrounding selector mechanism.

Functions

  • Provides the gear lever mechanism with its designated stop surface.
  • Helps maintain the intended limits of lever movement.
  • Replaces a worn or damaged plate during gearshift assembly repairs.

Technical Details

  • Part reference: 90142401700.
  • Brand: OE Match.
  • Listed in the 911 1965-69 transmission control assembly.
  • Also identified in the 911 gearshift control diagram covering model year -71/72-.
  • Sportomatic diagram coverage includes 911 1970-73 SPM; the 1974-77 assembly identifies this plate with the note -75 and model designation SPM.
  • 914 diagram coverage includes 914-6/4 up to 1972 and the transmission control assembly from 1973 onwards.

Symptoms of Fault

Indistinct lever positions, inconsistent selection or excessive movement warrant inspection of the gearshift assembly. These symptoms do not establish that the stop plate is faulty: worn bushes, linkage adjustment and clutch operation can produce similar complaints.

Why Replacement Matters

If inspection reveals wear or damage to the plate, replacement addresses that component of the lever mechanism. Check adjacent guides, springs, bushes and fixings before reassembly, rather than assuming a new plate alone will resolve every selection problem

FAQs

Does difficult selection necessarily indicate gearbox damage?
No. External linkage wear, adjustment and clutch faults should also be investigated.

Can adjustment replace a damaged plate?
Adjustment may correct alignment, but it cannot repair physical wear or damage. Confirm the condition of the components before deciding on the repair.

Like most European cars, the shifting is very sloppy and needs to be stiffen up. We have designed a lower short shift linkage that fits with the factory or aftermarket shifters. This linkage is 1 solid unit for rigidity using a plastic material insert which gives the shifter a stiff and accurate shift. The shift linkage fits over the stock cable housing giving you ability to adjust its tension for a perfect driving experience. The Agency Power shift linkage is then tighten down with an easy access stainless steel locking bolt.

Precision-engineered from durable materials to withstand constant movement, vibration and shifting forces, the cable end ensures accurate transfer of gear lever movements to the transmission. Proper operation of this component is essential for maintaining precise gear selection, smooth shifting performance and overall driving confidence.  

What This Product Does:
  • Connects the gear selector cable to the gearbox linkage assembly.
  • Transfers gear lever movements to the transmission.
  • Maintains accurate gear selection and shift operation.
  • Helps ensure smooth and precise gear engagement.
  • Supports proper alignment of the gear linkage system.
  • Reduces unwanted play within the shifting mechanism.
  • Contributes to overall transmission performance and driver control.

Symptoms Of Wear Or Failure:
  • Excessive play in the gear lever.
  • Vague or imprecise gear selection.
  • Difficulty engaging certain gears.
  • Increased effort required when shifting.
  • Loose or disconnected gear linkage.
  • Gear lever movement without corresponding gearbox response.
  • Rattling noises from the linkage area.
  • Premature wear of surrounding linkage components.
  • Complete loss of gear selection in severe cases.

Why Replacement Matters:

  • The gear linkage cable end is subjected to constant mechanical loading, vibration and repeated movement every time a gear change is performed. Over time, the internal joint surfaces can wear, bushings may deteriorate and mounting points can become loose, reducing shifting accuracy and reliability.
  • A worn cable end can lead to poor shift quality, difficulty selecting gears and increased wear throughout the linkage system. If left unresolved, severe wear or failure may result in loss of gear selection, potentially leaving the vehicle difficult or impossible to drive.
  • Replacing a worn gear linkage cable end restores precise gear engagement, improves shift feel and helps protect the transmission linkage system from unnecessary wear. An OE Match replacement provides factory-style fitment, durable construction and dependable long-term performance, ensuring the smooth, accurate gear changes expected from your Porsche manual transmission.
