Just installed a HSR and it is pretty tight on the TV cable. It reaches the bracket fine and hooks to the trottle body fine but it seem like there is some tension on the line when it is in the idle position and after it is attached to the TB . How far should the tv cable be pulling up on the rod in the trans in th idle position?Do I need a New TV cable and if i do what one? I seen the post from slvrvette but since mine was a tpi to start i think it is the same cable that he upgraded to. Thanks! also does anybody know the size of the bolt that holds the tv cable down?

Stock TPI cable worked fine on my HSR swap.
Have you reset the TV cable to correct position after install ?

The throttle valve cable (TV cable) should be adjusted so it's "just" tight at wide open throttle. If that gives you delayed and hard upshifts back it off about 1/32" at a time until the upshifts feel right. The TV cable housing is bolted to the transmission case with a 6mm bolt with a 10mm hex head. It's REAL easy to get the bolt cross-threaded so use extra care when starting it.

The TV cable has only one correct position.
It is not designed nby GM as a "shift adjustment" device
From a prominent trans site

" We have read lots of General Motors manuals explaining how to "adjust" the factory TV cable.
While most GM publications used the term "adjust", when you actually followed their procedure, what you actually accomplished
was to "set" the system to its correct W.O.T. position which will in turn automatically "set" the correct starting position.
We are not aware of a single GM publication that advocates "adjusting" the TV cable once it has been properly "set".
Not being "****" about semantics here but commenting on the wide spread belief that the TV cable system can be "adjusted"
to make the transmission "act" better.
As far as we know, this system was never designed nor intended to be a transmission behavior adjuster.
We further feel this is a very dangerous practice being performed by many "professional" transmission shops and mechanics.
Once a correct TV relationship is "set", you cannot re-adjust it without creating a problem of some type"

while it is true that GM never intended adjustment of shift "feel", using the TV Cable, there are aftermarket trans companies like Bowtie Overdrives that sell conversion kits to allow you to do just that .. without harm to trans http://www.bowtieoverdrives.com/catalog/catalog_inc/viewitem.php?ITEMID=218 .......... from their site .."unique systems linkage. Once installed, our unique cable pulling cam also provides the owner / installer a means of adjusting the shift timing and feel of the these transmissions during light and medium throttle driving. For a small investment of time, money and effort, you will be able to gain control of your transmissions "Personality" while absolutely being sure you are signaling for instant pressure rise to protect the transmissions frictions."

If memory serves me correct there was only 2 cables used from 84-92?.. I would call a short and long. Since yours is a TPI I am going to assume its the longer t.v cable. It will be a bit snug, check routing, and make sure your adjusting it correctly. It should work fine

I got it on there!!! had to reroute it around my wiring harness in the back of the block. I set it by connecting the tv cable to the throttle body and holding it at WOT. Then grabbing the cable crimp at the end of the fitting that attaches to the throttle body and pulling it. kept adjusting untill it there was no slack in the TV cable at full throttle.
