Remove the gear and leave the bearing race in place. Put everything back together.

The shifter will still be able to go for first... but you wont find anything. If you truly want the shifter to not even go near first.. then make a small alum clamp for the shift shaft that stops it from moving forward in the case.

I dont have any pics on this computer. It is very simple.

If you put a clamp on the shift shaft, won't that stop you from getting into 3rd and 5th also? (IMG:style_emoticons/default/wacko.gif)

There are 3 shafts. One for 1st/R one for 2/3 and one for 4/5

All you have to do is stop what would be the forward motion of the of the shift shaft. Just the distance that the slider would need to engage the 1st gear dog teeth. Leave the slider on the pinion shaft (if you want to keep reverse) and remove the actual "driven" gear from the pinion shaft. The drive gear for first needs to stay in place.

I dont know what the actual term is that the 1st/reverse slider slides on, but 1st gear sits on it also.

KenH has a nice set-up on his. It allows you to keep out of 1st and reverse when needed. You remove the lock-out bar and you can do as you please.

Yup, that's what I'm looking for a lock out bar or pin device that will allow to select 1 st when required. For example loading the car on the trailer or driving around in the pits and locking out 1 st when going on the track.

Ha ha.. I thought you wanted it GONE!!!

Sorry..

What I described above is for the V8 conversion guy's..LOL

Increase the spring pressure for 1/R and forget about it.

I just installed a 915 shifter I got from Seine Systems that was modified, adding a spring for 1st/rev to keep the shifter in the 2/3 slot unless you push pretty hard towards 1st/rev. I had to cut the ball off of the 915 shifter and weld the eyelet from the 914 shifter on the bottom, but I must say, it's the best shifting 914 I've ever driven, and it's not easy to accidentally get it into 1st. You can see it here- http://seinesystems.com/GateShift-901.htm
I also welded the tab on the left, after all adjustments, so I could remove the hose clamp that you see in the pics.

I had 3-4 failures from this exact "conversion" the welds broke every time. I had a certified welder do it after my first one broke.. For some reason that metal doesnt like to be welded!


Good luck!!

Painful subject:

Wish there was something out there that worked (under G loads) to eliminate 2nd to 5th mistakes.

Also 3rd to Reverse, again under load.

I figured it out: dont shift in the corner!!

Actually very few people have a car that can "lift throttle" and make an upshift in a corner without losing it...

"Don't shift in the corner"

Really (IMG:style_emoticons/default/blink.gif)


As to the fact that I don't have any issue with "losing it" during a load situation; that can be racked up to the talented guy who set up my car to run on slicks. (IMG:style_emoticons/default/smile.gif)

Never finished the drawing, but you get the idea.
Material is 1/4 steel angle.

Had a guy that fabs steel make it for me.

I can't wait until my most recent Sears in-car video is uploaded.
You can watch me upshift into 4th as I scoot past the apex berm of the exit of the Carousel...Every single lap. Whoohoo!! (IMG:style_emoticons/default/Jumpy.gif)

That section is mine... (IMG:style_emoticons/default/clap56.gif)


KenH, thanks for the pics. I'd like to make one of those for my car, too.

(IMG:style_emoticons/default/agree.gif) that's a big deal with the stock linkage. i always hated having to "drive around" my 4-3 downshift. under lateral load, the car would always want to hit 5th...

I have a Rennshift and it is a nice unit, but it wasn't designed to eliminate missed shifts at the noted (above) loads, i.e., those loads created with racecar type suspensions/slicks.

I have the strongest springs available from the manufacturer, but I think I'm going to find some even stronger springs. Maybe that will help.

Trek..

I think Kens is MUCH cleaner that some of the others posted, but a MUCH simpler solution was shown in the main forum.

My concern here:

If you get hit from the side.. your right leg has to get passed the shifter somehow. The stock stick will break.. this wont.

Through my years I have met two people involved with side impact wrecks in their 914's. Both walk with a limp after wiping out the shifter with their right knee.

Look at the other solution. It is VERY stupid simple and does not get in the way of anything.
