I seen the following post

I would like to do this with my L98 TPI engine but I would like to verify I am understanding this correctly.

I am understanding this as:

1. Car turned OFF
2. Press "D" button and have the cable housing (black) slide into the collar more towards the front of the engine.
3. Have someone else get into car and while "D" is STILL pressed down fully, have them press the gas pedal all the way to the floor and hold it as #4 is done.
4. While gas pedal is to the floor, pull the housing as hard as I can towards the rear of the engine (firewall) so that the throttle plate is open as far as it possibly can.
5. Release the "D" button.
6. Mark the cable at the back of the plastic housing to set a mark where the cable is just in case it ever slipped or want to reset back to INSYNC setting.

I read online that you just pull the cable to the firewall with the car off and it reduces the cable tension, however this resulted in my shifts being WAY up almost into 4000rpm. I ended up fixing it (or so I hope) when I pulled over like 15 times as I (without knowing what I was doing) slighting pulling the cable a click forward or back to see the results..

But I think it might be better to be doing it the RIGHT WAY ;-) not just randomly selecting a setting that SEEMS to be perfect ;-)

Thanks.

 

Just I found another method which is COMPLETELY Different so which is correct? This one looks like a completely SIMPLE 1-man process??

Umm.. this is explaining a Carb. I have a TPI. I don't see where it's saying which to adjust..

 

simply
1. Push and hold the "D" to unlock the cable and push the cable housing towards the firewall, release the "D" to lock the cable in place.
2. With the engine off, by hand, move the throttle lever on the TPI to full throttle (it doesn't matter what your floor pedal does). You will see/hear the TV cable housing move forward on it's own. This is Setting your cable...no adjustment necessary. DO NOT adjust this cable to get a firmer/softer shift...that is not what it is for...READ the above post in whole to find out why.
3. DONE.

OK, now you can adjust your floor accellerator pedal to achieve WOT on the TPI if needed...some people have to take the carpet padding out from under the carpete to achieve this.

 

As I'm sure you noticed when you read the page, they tell you all about how the linkage is the same. Doesn't matter what the throttle shaft is going into; the transmission part is the same. Just like it says in the text, about how they'll use the word "carb" for lack of a better one, but the exact same things all apply to FI applications, identical in every detail.

 

gr8apmech has it nailed in his post.

That's the way I did it. And it's "perfect."

 

Just about every time I have re-set a TV cable to the printed shop manual insturctions it has needed more adjustment.

Instructions tell you to push the button and push the slider all the way back towards the firewall..... then move the throttle linkage by hand to the WOT position. This action is supposed to pull the slider out to it's correct setting. Just about every time I have done this I have needed to pull the TV cable out a click or 2 more then the WOT setting sp the shift points were correct.

That's my experience with the TV Cables over the years !

 

I'm tryin to set my cable perfect. I'm having an issue with 2nd-3rd at wot, the rpms go close to 6k if I let them. I've tried 1 click and 2. I just cant get it perfect.

 

Spring in the valve body may be getting weak. Short spring is a common prob. That's why they created a fix. Get the spring kit that installs on the carb end of the cable. It has a spring that you install that 'adjusts' the cable through the full range of throttle...Or, pull your pan and remove the valve body and put a good shift kit in it...but be sure to ask for the TV Pressure spring. It normally isn't in the kits. (you could just replace that spring) All kinds of options...

I'm no expert, just a hobbiest like yourself.

 

Stock "tach"?

Probably means your "tach" is off, as opposed to anything being wrong with the transmission.

 

what does it mean if I have slack in the cable??. In other words if i push the D shape button and move the slider towards the firewall..I then turn my lever to WOT and the slider never clicks open. I have like another 1/2 inch of that stainless steel tv cable cord before the slider can even begin to click forward
