Make it tighter or lossing it up
--------------------------------------------------------------------------------
Let get started I got my New 357 engine rebuild bugs worked out.
I also have a new 700r4 trans in the car It shifts good during normal driving it has a Transgo shift kit in it not the full reprogramer one the step down from it.
The trans has all HD clucth stuff and a beast sunsheild in the trans also.
When on it hard it slips in to gear I was maunal shifting the car to see what it will do.
I was in 3rd passing a car about 3500 RPM it shifted it self into the next gear even with the shifter put in to 3rd gear still the issue was it went from 3500/4000 RPM's to 6000 RPM sliping the whole time before I got t o back out of it then it shifted in to High gear It was like some one push the clucth to the floor at 3500/400 RPMs then let it rev to 6000 RPM.
Qustion do make the TV tighter or lossing it to add more pressuer so it will not do this again.
I used the instruction that came with the Transgo shift kit to adjust the TV cable.
Like I said during normal driving works fine just when you on it hard it slips.

As it should unless you have a manual valve body

it went from 3500/4000 RPM's to 6000 RPM sliping the whole time

Sounds like the trans itself is slipping ; don't know that adjusting the TV cable is going to fix that

Obviously, because it is getting more load @ WOT

If the trans Is bad it would not suprize at all the place that did the rebuild I having thew BBB and the BAR looking in to him as we speak.

I trying to get my money back from the they screwed the car up Thats a whole anouther story.

I just save up the diffrence and order a Preforma transmissions next time.

I'm with Oz...
I don;t think the TV cable has much to do with it. This sounds like the wrong servo or relief.
Transmissions are just hydraulic pumps with their slave built into the same body. The transition between gears is just the timing of one gear/clutch or band releasing as the next grabs. The timing of this is what you see when the rpm rise during the shift...slipping.
One clutch is slow to react, either from a weak servo or low pressure.Why that is? only the trans dr knows for sure...

I can't help much about this kit but I can tell you that pulling the TV cable a couple clicks tighter, then working the throttle to WOT to "set" the new adjustment probably is'nt going to hurt anything. At worst, it will or should, make a gear run wayyyyy out before it allows an upshift. If its upshifting on its own, somethins wayyy wrong.

When set too loose or soft the TV allows the gear change to happen too soon, too quick. Its really trial & error to find the right spot.
