Precision Rear Shifter Coupling

Application: Porsche® 928 1978-95 all with Manual Transmissions

Background: The Porsche® 928 has two shift linkages beneath the 5-speed shift lever. One goes rearward to the transaxle, and one goes forward to the Shifter Ball Cup. This part is the rear coupling that attaches the shifter lever directly to the transaxle. It has a nylon liner in it that wears down after years of shifting, and the shifter gets sloppy. IN ADDITION, there is a designed-in air gap in the OEM coupler to prevent vibration from being transferred up into the shifter.

Our Precision Rear Shift Coupling is an all-new part modified with new polyurethane bushings to remove all the play in it, and we add an adjustable drag nut so you can choose how stiff you want it to be. We start with a brand-new Porsche part, disassemble it, replace the internal plastic bushings with polyurethane ones, then install the custom shoulder bolt and nut with cotter pin for you. Adjustment of drag in the coupler is as easy as pulling the cotter pin, tightening the nut a bit, and putting the cotter pin back.

How it feels to shift after this upgrade: Now you can actually feel the detents in the transaxle when you shift. You get positive haptic feedback to your hand as each gear clicks into position. It's very nice! If you rest your hand on the shifter, you will be able to just feel a very slight whirring of the gear sets in the transaxle. There is no sound transmitted, a gentle and pleasant "mmmmmmm" can be felt.

Installation instructions for this coupling are provided in the 928 Workshop Manual. We also provide an Installation Supplement. The rear shift coupler can be accessed from under the car. Look up just past the torque tube and just in front of the transaxle and you should be able to see it as shown in the photo below. It may be covered by a large rubber bellows.
