Well just for the record... and staying on thread.... The stock converter is doing the same thing. I am officially stumped.

Apologies to PI and their converters.

It is amazing the difference in how the truck drives with the stock converter. If my 60' times and 1/4 aren't drastically different I may stay with it. All the torque being wasted even below 2800 rpm. A kick down from 3rd to 2nd from about 40-50 is just amazing. Biggest thing I don't like is how hard it shifts with the stocker. The PI "soaked" up a lot of the hard shift. Anything beyond just idling to speed will snap the neck hard.

 

Some-one has been saying that for some time now, but NO-ONE listens.

A STOCK CONVERTER KICKS ***!


Can you post up a log of the trans doing this?

 

I might get to the track this weekend. I haven't done a full stall launch with it yet but it does fell like it pulls stronger midrange. Enough to overcome the 60' I think I will loose? We'll see.

I've attached the log that generated the screen shot from the first page of this post. I haven't captured the slip with the stocker yet but I bet it will look just like this one.

I am trying to confirm that it isn't tune related but feel it isn't. When it started I hadn't done any tranny related tuning in months. I put most of the tranny tables to a stock SS setup yesterday and its still doing it.

The major slip in this log happens around frame 6650.

 

can you send me a bin file? NO-ONE ELSE else will see it, ever!

Did you ever find out what was causing your problem? Mine is doing something similar.

 

No I haven't found it. As posted earlier in this thread. It is not the TC. I am leaning toward a tranny problem. Chuck @ FLT suggested going back to a stock tune or another PCM awhile back but it all started independent of any tranny tuning. He has also graciously offered to send me a different valve body setup like mine to try that. I just want to confirm somehow that its not in the tune or PCM. When I get motivated again I am going to pull the pan again and have a good look at the TCC solenoid.

I am officially stumped. Just driving it as is. Its annoying as hell. I've even considered finding a good stock tranny and throwing it in to see.

 

KySilverado this is what the tranny shop found that was wrong with mine.

The bearing race on the beast sun shell was broke and they found pieces of it in the valve body.
