Part Of Shifter

[markmcintosh]

I purchased my 79 SC last year and re did it, and I am wondering what this Blue part is on the shifter?

I have no idea and it moves up and down each time I shift, I have never seen one before, thought someone on the forum might have.

Thanks!

Reminds me of the Seine shifter. But being blue makes me think Stromski racing.

looks similar to a Seine Shifter...

Whether Seine or Stomski, this assembly is what is giving you a centering action between the 1-2 and 3-4 gates. It is aftermarket.

Got one in the garage, never installed. The more I looked at it, the more I wondered why I needed it if things were adjusted properly.

I have a seine on my 85 911 and like how that side spring centers the shifter in the 3-4 plane. it makes moving over to 1-2 plane requires a little pressure, just as the stock spring makes moving to the right for 5-R require some pressure. makes the shifting not feel so sloppy/floppy.

cheap upgrade compared to the Wevo, which I will be installing in my 78 930 build.

Thanks for all your help! Clears things up for me!

The main purpose is to keep you from accidentally downshifting from 5th into 2nd and cost you a new engine. It is just an insurance, but it really has a purpose, and it is inexpensive.

I'm in the market for one if you'd like rid of it. PM if so.
Thx.

Oh, no - don't remove it. It took Porsche an unconscionable number of years to realize they should spring load the shift lever into the 3/4 plane. As soon as they went to cable shifters, they did that. Maybe with the G50s even earlier? But never with the 915 or earlier.

With this gizmo, and replacing the oval bushings back at the shift coupler which connects to the transmission with round ones with zero play, you have a completely changed shifter.

It is a good idea to weld tabs onto the shifter plate, and a hook onto the shift lever, on the left side, similar to what Porsche did over on the right for 5th and reverse. This takes the spring pressure away from inside the transmission in 1st and 2d. The transmission wasn't designed to have constant twisting pressure on the dongle inside the transmission when in a gear, and without tabs you get some noise. I don't think that actually hurts anything, but it does put a constant pressure sideways on the brass yoke fork which engages the slider/engagement piece, and that can't be good if you are in 2d a lot. Not usually in 1st long enough to matter.
