Racing a M6? Please read!

I developed a 5th/6th/reverse lockout for the T56 six speed trans. I'm trying to gauge peoples interest and see if any one local is willing to try it.

I built it to solve the problem of my shifter nailing 3rd but the trans doesn't. I always ask people if they have seen this problem, and never came across anyone. It seems to be rare.

The lockout should also keep a 2-5 shift from occuring.

I fried my Centerforce and decided to commit to an automatic. I never got the chance to try it.

I made one prototype and I'm willing to make one or two more to give to people if they are willing to try it and provide feedback.
It works electrically, so a button is needed to access 5th/6th and reverse.
It's easy to install.

Please email me or post if interested.

Thanks

I'd be willing to give it a try. I race the car almost every weekend and would really be able to put it to use.

Also, could you possibly look at adding a arming switch so that a button is only needed temporarily while at the track?

I work up in the Utica/Washington area but live in Grand Rapids. Fairly local.

Cool, sounds like there some interest. I'll start making a couple more. I have to think about the arming switch. It's a pretty good idea.

I am not exactly shure what your talking about.

Personally I miss 3rd sometimes when racing (I have missed 3rd about 3-4 times, and 2nd once, no other gears).

But why would you need a 5th, 6th, or reverse lockout?

I mean it automatically locks out reverse once you get going (not shure what speed). And it seems to lock out each gear once you get out of its speed range (at least 1st and second).

And I have never shifted into the wrong gear (meaning 2nd to 5th, or 3rd to 6th, etc) while accelerating, exept the first 2 days I was learning to drive.

I would be willing to demo it, if I had a clue what it actually was for http://web.camaross.com/bb/confused.gif

Brian, I just talked to your brother about your automatic. That things gonna fly!! Shoot me an email on the tire you were looking for. I've got a place for you, that can probably get what you are looking for. I gave your brother the # if you want to just call him.

Dolby109,

The main purpose is when you are shifting the trans like an absolute maniac.

When I would treat the trans with respect I would never miss a gear. It seamed like every time it counted, 3rd gear became a problem.

In my case, I think I would move the shifter foreward when it was in between 3rd and 5th. There is a gate under the middle cover of the trans that forces the shifter into 3rd or 5th. But before it gets forced, the pin that actually grabs the 3/4 or 5/6 rail is already heading in the middle of them. Once it started its path down the middle it couldn't return. The result was the shifter would be solidly in 3rd gear but neither the 3/4 or 5/6 rails were ingaged. Just from the feel of the shifter you could tell something was bending.

My idea was to take the reverse lockout that GM or Borg-Warner designed and extend it into 5th and 6th. This way you are gauranteed that your shifter is lined up for 3rd gear.

I still have to do a little more research. The prototype I made is from cold rold steel. It works well, but I can tell just from shifting it on the bench it will need to be hardend.

The other thing I need to research is the skip shift. My car is a 93 Z28 and it never had it, so I don't know how it works.

If any one can help with the metalurgy or the skip shift please let me know.

Thanks

I can get hardend cold rolled steel from work. I work at Fastenal Co. I can get it cheap to. Let me know some dimensions.

Oh here is a quick and easy way to fix the skip shift crap.

Thanks for the skip shift link and the offer for the metal. I wish I checked this board earlier, I already ordered some 4140. A metalurgist recomended it based on what I described to him.

Just wanted to let you guys know, I'm still working on this. The 4140 metal came in. Waiting on springs. Depending on how long it takes to heat treat the parts, I should have something within a week or two.

Today I recieved the springs (I ordered them over a week ago). I modified the prototype to work with the new springs. It seems to work pretty good on the bench. Tomorrow I'll start making 5 more and then it's off to heat treat.

Tanner, I'm definetly planning on sending you one. I know you're doing some slick shifting to pull that ET.

Thanks

Brian,

thanks a bunch, i 'll be throwing the 35 spline full locker into the car this weekend http://web.camaross.com/bb/smile.gif and then it is off to the races, hopefully in a week or two. it will be my next attempt at singles digits (on the left side of the decimal place that is)

hell i can even pick it up if you'd like me to? i will ssend you my cell number.

This must be what happened to me the other day. I shifted to 3rd, let out the clutch and just revved the engine. It felt awful strange pulling it out of 3rd, and it hasn't done it since. I was getting on it a little and doing some quick shifting.

Sorry to here that your trans is doing it, I'm happy to here I'm not the only one though.

Every time it's happend to me I get the frustrating comment, Oh you can't shift.

By the way, if this lock out doesn't fix this particular problem, I also came up with an idea to reinforce the pin so it can't bend. I did it to my trans. The only problem is it involves completely disassembling the trans and welding a boss to the side of the case.

I'll be driving it this weekend, so I'll see if it happens again. Maybe being aware of the problem will help me avoid it.

Just an update. Finally finished them. I'll drop them off tomorrow to get heat treated. They said it would be a one day turn around. Not sure maybe two with the holiday. I made five of them, hopfully all of them make it through the heat treat process.

i will be in the livonia area tomorrow, call me if they are done....lol!!!!
shoot me an email when they are ready.

have you thought of cryogenic freezing? there is a place in windsor that does it. let me know?

Taner, cryogenic freezing doesn't really strengthen the part that I'm aware of. It allows force fit parts to drop together. By freezing the pin and heating the hole they simply pop together (just an example). Once the parts return to normal temp their material properties will be the same and they'll return to normal size. This works great in die making when you have to dowel pieces together. The freezing drops the pins about .001/.002 and heating the hole a bit makes them drop right in!

If there is a cryogenic process that strenghtens though let me know. I haven't heard of it and would like to look into it some more!

I droped them off at a place that works 24 hrs. They should be done tonight. They are shutting down for the holiday early tomorrow. If I get there before 10 I should have them.

Sorry guys, I called this morning at 8:00, to see if they were done. They are done, problem is they close at 8:30 not 10:00. I'm in Livonia, the place is in Madison Hgts, I would have had to drive 120 to get there in time. I'll have to wait until Monday to get them.

OK, I have 5 of them ready to go. If you guys are still interested, then drop me an email. Can either pick up from my house or I can ship them.

NOte: to the users of this lockout, mine is in and will be put through the paces tonight @ Grand Bend, one thing I experienced is I blew my fuse for the fan (10 amp) I upgraded to a 15 amp fuse, hopefully this will suffice. the fan and lockout are on the same fuse. I will post back if the 15 amp fuse is not enuff.

Taner,

The resistance on the lockout solenoid is 13.4 ohms which means it will draw about 1 amp when it is on. I wasn't sure if the factory PCM was fully turning on the soleniod or duty cycling it. Since you're blowing fuses I suspect it was duty cycling it.

I looked up the circuit. Both fans, the EVAP canister purge soleniod, exhaust gas recirc motor, and the reverse lockout are all on the same fuse.

PLEASE KEEP A CLOSE EYE ON THAT FUSE! I don't want the lockout to end up overheating your engine or burning out your fans. I appriciate you testing it, but the last thing I want is to damage something.

If your feedback is positive, then Monday I'll talk to one of the engineers at work about comming up with a circuit board to duty cycle the soleniod. It should significantly lower the 1 amp current draw.

Thanks
