305 TPI 700-R4 TV/detent cable
 

My buddy has a 1987 IROC-Z, 305 TPI, 700-R4. He's having trouble adjusting the cable for proper shift points. I never had this problem with my 700-R4, so I am of no help. Anybody have any advice on where the shift points need to be? BTW this is a bone-stock 305, so whatever the stock configuration is will probably work best.

On mine you just press the "D" on the cable housing mount, on the TB. It self adjusts when you push the "D" button in. Of course mine is a manual now though.

Here's what you do. Push the cable cone as far back towards the firewall as possible, you don't need to use gorilla strength either. Now you can press the d-button on side of the cable OR rotate the TB swingarm to WOT and hear the clicks. Then you are set. Thats how I do it and have no issues in the 12 years I've been messing with TPI. And actually, I don't know how anyone can mess it up anyway, because as soon as you go WOT, the cable will adjust it self to that point anyway.
