Trans shift vacuum question

[pontiac6ksteawd]

i would like some pics of this. Mine only does it under WOT, I just thought it was from lack of vacume, but if there is a way to correct it...

[Prospeeder]

Pics would be great, thanks! Id like to get it cleared up, it feels bad for the car

Okay, here we are, first off, obviously, these pictures aren't from the TGP, since well, its like impossible to get a good picture, well, i think I got like 2, without destorying it, and the extra one we used to have from our Lumina engine we cut up for experimentation, so this will work, from our '90 INDY which I might add I hit the hood prop and dropped the hood on me!!! :x , same concept though, I uninstalled my photshop during reformatting time, so I had to use PAINT to resize them............and we are off.....
TGP....you see that circular with the line coming out the center, which is the TV cable right, yes, it is.....


On the top of it behind the big cicular thing *from looking at the first picture, there is this, with 2 shiney metal "things" on it....about middle of picture with a hole in the center


Here, close up view...*linked because its not resized....*

I'm a skinny mini so I was able to reach my hand down too it.  This is how I went about it.....Standing on the driver's side, by the fender, reach over, stick your hand down between the firewall and the back of the engine, its like directly below the purge canister solenoid, using my right thumb, pushed down on it....then with the left, slither down under the EGR, push the thing in the center of the connector in, there is a little CONE type thing, if you look in the first picture you can see it slightly, its what the cable comes out of, it will go quite a ways in when you are pushing the thing down, if not, push harder or find a way to use a big object that you can push it down with....THEN, after its retracted, take the right hand and OPEN the throttle body, you will hear the thing click, which is does when you push it it, you open the TB all the way, WOT, and then let go with the left hand on the "button" I'll call it.  That should put it pretty close to what its at.  My poor back has about 2 cuts in it or I would go outside and look in the manual, or someone will chime in, but you do a test drive and at partial throttle you check to see what it shifts at RPM/Speed wise, and that will tell you if it needs more adjusting, I believe the more IN the cone type thing is, the higher the RPM/Speed must be at partial throttle to shift....

I hope this explains it well enough, any more help needed?

Just in case anyone else had trouble telling what was what in the above pics, I happen to have a cable out in my trunk so I snapped a few quick close up pics.  Hope they help.

well ya have the right tranny for hard shiftin  :P

just bustin the majorities chops a bit  :wink:

erm, so theres the button, the further you press it the more it adjust or what? or u press it as far as it goes? And then open the throttle all the way, let off the button, then let of the throttle, and it adjusts? How do you adjust it more or less, i didnt see that part? just press the button more or hold it longer or what

No....

You press the button to allow the thing to adjust....The little "cone" thing at the end down by the end is what you adjust.  Push the button down, then push that "cone" thing in, then, while still holding the button, you open the throttle and it will click and the "cone" will move out.  Open the throttle ALL the way while holding the button, then let go of it, then you are done for the first part.  The small adjustments are probably easiest with just pushing the button in and moving the "cone" in a couple click, you may be able to move it out some too.  Like I mentioned before, I believe that the further IN the "cone" is the higher the RPMs must be under partial throttle for it to shift.

Nuh uh! No way! Nope! :wink:  :lol:

I will take a manual over an auto anyday! Cheaper to fix, more power to the ground, and just plain more fun! :wink:

dont listen to the clutch dumpers, and shift fumbling whiz bangers. :lol:  :roll: they are used to keeping their hands busy with knobs :P

just remember to double or triple heat shield the cable as it runs down in between the x-over,turbo and downpipe, otherwise the thing will strech (if it hasnt already 'turboblanket? Y/N') from all the heat. even crack off the plastic cable housing.new ones are $150+ so I hope yours is not all streched out yet.

[TGPilot]

My turbo is not insulated and I have never had an issue with heat. No cracking or stretching at all. If you use the dimpled hole in the floorboard to run the shift cables out you will not come any closer than 6" to the downpipe and they are a long ways from the cross-over. I will have to look at it again...but I remember being nervous about the fitment when I was mocking things up 3 years ago...but was very relieved when I saw where they were after it was bolted together.

the plastic covering the TV cable in my TSTE is all cracked up and coming off due to the heat.  and it had the original turbo blanket on it too :(

manual shift cables are a different story.  they don't come very close to the downpipe but i do have mine wrapped in Thermo-Tec heat wrap from Summit anyway.  i have my regular NA 3.1 fuel lines wrapped it Thermo-Tec heat wrap as well because they are sort of close to the turbine housing.

And like I said, Us Drag racers :P

Its a never ending no win battle, I could go into the torque/low end/launching/etc.etc. with the two and it would be the same outcome, yes no thing :lol: Good debate material there, haha....

On Topic, My TV cable down between turbo/crossover still looks in pretty good shape actually, it still works so I'm not going to fix it, don't fix what isn't broken they say :wink:
