TV cable

I can't leave my TV cable alone. I have a 1998 (46RE), so the cable has the notches on it and the little white plastic clip. I know the older models were set up a little different. Basically, it seems like there are two settings you could reasonably leave the cable at. One is when unhooked from the TB, the clip is just about in perfect alignment on the stud on the TB. In this setting, the truck downshifts to 2nd less, and I get almost 1 MPG better. The trans doesn't slip, but it shifts a little sooner and not as firm as I'd like. I assume this is the factory setting, having read through service manuals on how to adjust it. The other setting is one tooth rearward, towards the firewall. When the trans was rebuilt (both times), this is where two different shops adjusted it to. Probably because they like the firmer, slightly delayed shifts. I do too. The only thing I don't like is occassionally, when applying progressive throttle in 3rd gear, the trans will drop down to 2nd for no apparent reason, and then go back to 3rd. Once this annoys me enough, I go back to the first setting I mentioned (probably stock). Then I eventually want the firmer shifts again and go back to setting number 2. Its a vicious cycle. I will eventually break the clip or lose my mind. You guys that have been around these trucks for a while, where do you have yours set? With the cable unclipped from the TB stud, is it in alignment with the stud, or do you have the cable slid one tooth back towards the firewall? If you have it one tooth towards the firewall, do you get that annoying drop from 3rd to 2nd and back to 3rd again occassionally? I'm considering seeing if the BW GP sensor/ selenoid helps with that, but I hate to waste the money if its unrelated. I was told all electronics were replaced when it was rebuilt, but have no way of knowing that. If they were replaced, I could already have the BW unit in there, but I don't know how likely that is. I also wonder which setting is best for transmission longevity. The setting with the firmer shifts seems like it would be better for the trans, but I don't know if that is true or not.

May ask the trans shop about it. Still under warranty for about 6k more miles, so I can't do anything myself now. Took it back and told them about it a while back and they just loosened up the TV cable a bit, which helped, but didn't make the goofy shift go away completely. Hard to find time to leave it with them, ya know. Daily driver.

I wouldve thought the pressure would be high, since if you tighten the TV cable, it acts up more. Was thinking tightening the cable made it shift at a little higher pressure. But, I don't pretend to know squat about an automatic trans. I can adjust the TV cable and change the fluid and filter. Other than that, I gotta trust someone else.
