1984 5sp Won't Enter Gears

Hi everyone, 

I have a 1984 928 5sp that I've been slowly working on catching up past due maintenance. All while regularly driving the car. 4 months ago, while driving the car, the clutch pedal went mushy. Since I was far from home and around a certified classics Porsche dealership, I figured it wouldn't hurt to check the car in with Porsche and have them look over the car.

I was quoted a lot, but the issue at hand was replacing the clutch master/slave cylinders, the brake master cylinder and the clutch/brake lines. After 3.5 months of the dealership working on my car, I got a call telling me my car is ready for pickup. Once I got there, I tested the clutch pedal and the travel distance didn't feel right. I started the car and attempted to enter a gear and it won't. It grinds first and reverse and simply will not enter 2-5. 

The dealership washed their hands from the car saying I need to do more work: replacing the clutch, maybe the flex plate is broken, inspecting the transmission for possible broken parts. How can a driving vehicle be immobilized after replacing the clutch master/slave cylinders and the brake master cylinder? I have been disputing the service and charges from the dealership but I am looking to figuring out what possibly went wrong.

The most frustrating part of it is now my 928 doesn't drive and it will sit indefinitely. Which we all know will cause further deterioration.

Any insight from the experts would be appreciated. 

Thank you, 
Clyde

Hi Rich,

I really appreciate the response and direction. If I'm understanding correctly, the intermediary plate should have been readjusted.

Thank you,
