Skip between 2nd and third

[Rusty knuckles]

So my BB 727 has been having a kind of weird skip between 2nd and 3rd upshift. It's like the trans goes to neutral briefly before going into 3rd. The rpms jump up a bit as it's doing it. It does this both in drive and if I shift manually. Not sure if it's related or not but it doesn't seem to down shift correctly under acceleration. But if I shift manually from drive to 2nd the skip doesn't seem to be there. I've checked the kick down and its adjusted right, full pressure at WOT. I don't think there's any slippage while driving, just this skip between 2nd and 3rd. I also think it upshifts too fast. Its trying to go to 3rd by 30mph. Any thoughts?

Adjust the kick down. Forget about what you think is right. You need more throttle pressure.

If the trans has a lot of miles, it may just be worn clutches & bands. Any history on the trans? Is this a new problem?

Not a new thing. It's been doing it for some time. I've never had the trans out and had the car for over 20 years.

I'll do that.

I would adjust the kickdown for higher shifts and see what that does. It sounds like it's time for a transmission fluid and filter change and while the pan is odd, adjust the bands according to the Factory Service Manual.

I was in a lot better shape 20 years ago! I would recommend going through your Torqueflite.

As noted adjust the kd band. Kim

Any updates? Kim

There are basicly two possibilities that will create this condition, Changing the fluid, adjusting the bands will do nothing. Either there isn't enough throttle pressure (Kickdown) due to the linkage not pushing the lever back far enough. Or the high gear clutch frictions, seals, or reaction shaft rings are worn out. There isn't any magic fix. If the linkage adjustment doesn't help? It needs to come apart.

No. There's no more adjustment to the kick down i can do. So may be time to drop the trans or at least the pan. I haven't done that yet though.

No sense dropping the pan. There is nothing that you could do to cure the issue if it has full kickdown. Maybe the thottle pivot weld is broke. But I've never seen one break in 45 years of doing Torqueflites.
