Has anyone installed the shift kit shown in the pic? There are several changes in the kit. There were 2 options for firming up 2-3, one firm and another firmer. Likewise there were 2 options for softening 1-2, one soft and another softer.

I was hoping someone has installed the kit and what options they thought was best for the 928. I don't think I would mind firming up 2-3, but not sure I want to soften 1-2 much.

Hopefully someone on the forum has done this.

Also, I found this diagram by doing a search in Rennlist. Has anyone done this mod to get the 4-speed auto to start in 1st in drive, versus manually shifting it?

Mike,

That is a cool exploded view. Thanks for sharing.

If have searched too and there are several threads on similar topics but there doesn’t seem to be a definitive consensus.

Surely someone (anybody out there race autos ) must have done extensive research and experimentation to get their car to shift “just right”.

What would be way cool is a write up with that exploded view, all the options for each component, and how the various configurations affect shifting.

Any takers on putting this together?

Mine starts in 1st every time, not sure what was done when it was rebuilt.

I installed the shift kit last winter and used the firmest springs. That made shifting slightly too firm. Perhaps need to go for one step softer in future.
I agree, there is now need for soften the 1 -2 much. The gearbox shifts now very accurately up'n down, also no negative side effects detected so far.

Don't forget to adjust modulator pressure accoding to WSM. There are two different modulator pressures for two different version of gearboxes, check your version first for using correct pressure.
Last step would be to adjust the cable length from throttle linkage for shifting points you like.

Regarding the picture of modifying the later style box to start with first gear. I did extensive search from MB forums as the same picture has been there as well.
I gave up after one MB guy wrote, that he tried the spring change modification and box really started with first gear, but always shifted only after 4000rpm or so

Did you leave the stock springs in for the 1-2? You did not change anything? Just want to verify.

Also, when you said it was too firm, are you referring to the 2-3 springs? I assumed you did both updates for the firmest 2-3?

Simos: Nice hood ornament in your avatar! I would think that the best view however, would be from the driver's seat! Now, back to the subject at hand, er................. I mean what the topic is about: I installed the shift kit where it starts in first gear a few years ago and IIRC it was also designed to eliminate some 2nd-3rd shift flare (slipping) common in the MB trans. You also had the option of first gear starts just by reversing the spring location in front or rear of some whatchamacallit. It's pretty easy-smeasy when you are doing a fluid and filter change. It works for me with no issues

All I need to do is switch that spring around and my s3 will start in first gear?

'83-'86.5 4-speed autos always start in first.

Podguy

No they do not. Everyone I have starts in second. The 190D mercedes I had started in first but shifted to second almost as soon as the car was rolling. Not a bad compromise.

Really can it be that simple to get a first gear start. I have seen people selling expensive kits for this.

PorKen

Yes, they do. Or they should. Even some early '87s.

Your control cable(s) may be stretched/loose.
Tighten the cable so that the socket drops straight on to the ball.
(Tighten 1 or 2 additional turns for faster response.)

Podguy

Ken you have a completely different experience from my cars. One has had three different transmissions all started in second and had to be shifted to 2 before starting in first

My 86.5 also usually starts in 2nd gear. Sometimes, depending on the position of the moon or something, it will start off in first but go to second as soon al it goes faster than 10 mph.

The only way to get consistent first gear starts is to put the selector in 2.

My Bowden cable is adjusted correctly and modulator is OK.

Cheers
Michel

For the record here. Oh, I'm back by the way. Trolling.... The 4 speed starts in 2nd. This was told to me by 928 international. It makes sense because when you engage the kickdown, it drops to first gear. So in a word, you can take off with the car in first gear as long as your foot is to the floor with the kickdown engaged.

depami

My 86.5 starts in 1st every single time. It doesn’t matter at all how hard, or light, you push the pedal, it starts in first EVERY TIME. If you are barely on it the 1-2 shift is very quick at about 10 MPH. If you are completely on it the 1-2 shift is near red line.

This topic has be discussed, argued is more like it, countless times with no mutual consensus of original intended operation. I tend to agree with Ken that something is maladjusted for an 86.5 to start in 2nd. I have never researched it but didn’t Porsche ever publish anything on this topic?

Now, back to our originally scheduled programming; how cool would it be to have an in depth, comprehensive, accurate review of these so called shift kits?

I think this would be way cool.
