can those parameters be scanned with a PT or is it a special scan tool?

PT can scan them. He already responded.

Hi Bill, if you can view TCC slippage and Duty % then it will help to see
what is going on. There is also a TCC ON or OFF data line as well if you
have that available. The TCC slippage should be roughly 0-50 rpm all the
time when the torque converter is locked up. Duty % will vary anywhere from
20%-70% while TCC is ON. It will show 0% or 100% depending on your scanner
when TCC is OFF. If it tries to lockup and slippage is constantly above 200
rpm it will dissble TCC operation and throw a trouble code and it will save
in the history of codes in the pcm. A quick test to verify operation is by
going down the highway at crusing speed and lightly apply the brake pedal.
If the rpms go up a few hundered with the brake lightly applied then it is
working. After you release the brake pedal and you should see the rpms drop
back down a few hundred. There are a LOT of causes to make this happen,
check your fuses first to make sure you dont have a blown one as the TCC
solenoid generally gets its power through a purple wire going to your brake
switch under the dash. I hope this helps and let me know what you find or
if you have any other questions.

that's really interesting... I wish there was a way to "subscribe" to or "save" certain threads for easier reference. I want to start looking at all my transmission related settings and scanning those aforementioned parameters with the powertuner and see what I turn up... and if they are consistent with what he's saying.

Yeah I was looking for a site that had engines for sale, and i found that one through google. Anyone know where I might be able to buy a long block l67. I believe a rebuild for my 280,000 mile engine would prolly just be better off with a completely new engine. Starting with a long block. But hte first thing Ive got to do is beef up the tranny. ive got 200 bucks right now. With 200 more every week.

I just meant like a way to subscribe to them so you see when they are updated and such
