700r4 TV cable too short? Thoughts?

Hi HotRodders,

My project is using a SBC with a 700r4 transmission. The fuel system is a Tuned Port FI set up from a 1986 Chev Camaro. I am having a problem adjusting the kickdown/tv/detent cable. I have purchased a new cable using the ‘86 Camaro as the application.

When I go to adjust the cable I cannot get wide open throttle. The cable is maxed out as far as adjustment is concerned but the butterflies in the throttle body are only opened about a third. I can pull the cable by hand easily when it is connected to the transmission. Said another way –I can feel the resistance from the transmission so I know it is connected.

I have tried a couple of longer cables from different applications. This doesn’t work because I cannot take up the excess length with the adjustment. This makes me think the Camaro cable is the correct application. Is there a chance that I got an incorrect or poorly made cable?

I am not a transmission expert. I am looking to the group for some thoughts as to what to try next.

Hi,
Are you depressing the re-adjust tab on the T.V. cable?
Depress the re-adjust tab, move the slider back through
the fitting in the direction away from the throttle body until
it stops against the fitting, now release the re-adjust tab.
Good luck,
rich

Go to Bow Tie Overdrives online http://www.bowtieoverdrives.com/index.shtml they offer linkage adjustment kits that will provide the correction you need for your application. Your problem is in the linkage geometry (arc).

700r4. How could it change from one vehicle to the next?

Your problem is in the linkage geometry (arc).[/QUOTE]

Thanks for taking the time to respond to my post.

I don't see what has changed from the Camaro to my car. The geometry(arc) is determined from the cable mounting boss on the plenum to the throttle body. The arc from this point is independent from the vehicle. Unless I am mistaken.

Please advise.

Possibly I misunderstood is this a stock setup? engine/transmission combination or have you just changed to the 700R4? If this is a stock setup and you are just changing the TV cable you have something in the wrong location or not getting the detent pressed in completely on the TV cable at the bracket before you press the throttle to the floor. If this is a conversion your problem is most likely in the geometry on the Throttle body linkage if it was not originally set up for the 700R4. Are you using the stock mounting bracket for the TV cable in the stock location?

Bracket follow up and Project details.

I am installing a SBC w/700r4 using TPI in a Jagaur XJS.

If this is a stock setup and you are just changing the TV cable you have something in the wrong location or not getting the detent pressed in completely on the TV cable at the bracket before you press the throttle to the floor.

I pressed the detent in and the adjustment is all the in ( the adjustment sleeve is extended all the way toward the throttle body). I cannot go any further.

If this is a conversion your problem is most likely in the geometry on the Throttle body linkage if it was not originally set up for the 700R4. Are you using the stock mounting bracket for the TV cable in the stock location?

I am using a stock engine, trans, and TPI unit in a Jaguar. The TPI unit is not modified.

Was the 350 and 700R4 originally mated up and was the TPI on the original setup, are you using all the original bracketry in the original locations?

The engine and trans have been paired since new(1992 GMC VAN). The TPI system was purchased seperately(1986 Camaro). The detent cable bracket is the one that came with the TPI unit.

Thanks for taking all the time in trying to help me out. I do appreciate it.

If you are sure you have it in the trans correctly and have the correct bracket and the TPI unit was originally set up for the 700R4 I might suggest getting a universal TV cable such as Lokar (which is what I have done) then you just have to get the trans pressures set correctly and there are several post on the board on how to accomplish that. Others on the board may have better suggestions give it a day or so and see what you get.

Follow up.

I ended up buying a genuine GM detent cable. The GM cable installed and adjusted with no problems what so ever. The adjustment mechanism seemed to be better built than the other brand I bought.

Thanks to all that replied.
