700r4 Owners:TV Cable Setup Problem
Hi folks,
I just finished installing a new 700r4 transmission after my last 700r4 blew up. The TV cable is giving a bit of a problem. I'm using the same cable that was on the car.
The "throw" of the TV cable appears to be different on this new transmission. I have a pressure guage hooked up to the trans and I'd like to set the initial pressure between 90 and 110 psi. This is the typical range. I have to extend the TV cable pretty far out to get this reading. So far, that it prohibits full throttle.
That is not ideal.
I can't get this at the right pressure & full throttle at the same time. The only thing (I think) that will effect the length of the cable extension is the mechanics by the plunger under the pan.
Am I missing anything?

I asked my builder and checked a few places on the web like..

I wish it was that low.

Jack,
I am not a fan or spokesperson for BTO,as you may have read about my dealings with them,but they sell a TV setup that works perfectly. There's some pics on my website if you run a Holley you may want to look at. The kit comes with the bracket and carb cam that puts everything in correct geometry.My pressures checked out perfectly,per the BTO tech support.(I later blew the trans with a single 6500 rpm shift,but that's a whole different story)

For as many overdrive tranny upgrades as members of this forum have done there are not many threads that actually list the tranny pressures for all gears and neutral. I would have to search to find my data. I have it recorded somewhere and will look.

My temp is typically between 160 - 180. I also have a trans cooler on it that helped a lot.
I think the solution to this problem is to swap the plunger mechanics from the old tranny. I noticed they were slightly different when I had the pans off both units.

i hooked mine up with the trans pan dropped so that i could see both WOT and the plunger being depressed.....this worked flawlessly and then used the pressure gauge to verify everything was set correctly. i also used the BTO stuff and also used there instructions.
