Attitude monitor....TC lockup???

[MikeBeggy]

I have been watching the TC lockup on my 05 and if the attitude is correct, lockup only occurs with boost of 8 or 10 psi. (turbo boost). Has anyone else with an 04. 5 or newer 48re noticed the lockup chacteristics? I'm looking to compare notes before I decide if it's acting normally. Thanx for your input.

TC lockup w/Attitude

Mike, My 4. 5 48re 3. 73 2WD in overdrive likes to lock up around 48 mph, I haven't noticed it being boost dependent. With the Tow/Haul button pushed in I'm not sure, I'll try it and try to provide an update later. Hope this gives you some info.

I was changiing the monitor from slip to lock today and watching the changes in the display. It shows that the TC locks and unlocks repeatedly above 50 mph. Seems to cycle every 2 seconds. The trans is definitely NOT locking and unlocking every 2 seconds. I guess I'll be calling EDGE to see if there is a diagnostic routine to run or maybe I just got unlucky with my unit.
