I am going through a transmission. First gear is supposed to have only 1 brake band. All other gears have 2 brake bands. Upon inspection, I find that my first gear is setup the same as all the other gears. It has 2 brake bands and the same stop blocks as the other gears. I really don't understand why Porsche did first different except to save money on 1 brake band. I do understand that synchronization is on the down shift and two may not be needed. Question is, should this matter? Is there some advantage to the way first was setup by Porsche?

It sounds like the last person to rebuild that box didn't want to spend the $$$ on a 1st gear syncro, so they exchanged it with a 2nd-5th syncro. By doing so, you must also use the 2nd-5th brake bands and blocks. This is what I did when I rebuilt mine at Dr. Evils clinic last year. It's really common and works as normal.

The P.O must have changed the dog teeth. The Dog teeth are different for 1st gear. There are 2 notches instead of 1. Because the lower notch is missing, the stop blocks won't fit. I put it together as it was. I am sure all is fine. |
