After 6 speed build no lockup?

Shot in the dark but the converter won't lock until it hits a certain temp (87.8 F in a stock 2005 tune, for example). Can you log trans fluid temp to be sure you're getting a signal from the sensor? I'm not sure about this one specifically but I know a lot of readings default to the minimum value when they are unplugged or the circuit is interrupted.
" Seems to lock " doesn't tell me anything. If you think it locked, look at the slip rpm and it better be " 0 ". Then you will know it locked.
I was unable to arrow down to the slip rpm once I enabled the lock command. The screen was frozen once the command was entered. It was definetly a positive engagement going thru the gears.
Which solus do you have? If it's a newer one before you start the test you can click on the check mark in the top corner and deselect all pids, then just select the ones you really need to see. If you need more help on pid selection I can take screen shots as I use a solus daily..
If your not on a solus anymore ignore my post

Its actually a Modus. There probably is another way to make this happen other than the way I did it. I went into transmission functional tests and tcc on/off. I selected on and from that point the screen would lock and not let me scroll down to view slip values.
Modis has same functions.. I'd set it up so you only have like 2-3 pids and then you won't have to scroll. Maybe it'll work? I don't have one to try it on to see.
Well I got my hands on a Gennesys scanner and was able to monitor tcc command psi which was 0psi. Also was able to monitor tcc slip rpm and lock the converter. The converter would lock / unlock whenever the commands were pressed. The converter had 0 slip when locked. The fact that the tcc solenoid only reads 0 psi it has me thinking it is bad. I will use a dvom and test solenoid and wiring tonight. Mike L I might need a tcc solenoid. Also a fitting to test psi just so I know what it is.....
I am just thinking out loud here about my tcc not locking up. With me being able to lockup the converter manually with the scan tool isn't that the same electronic circuit that the tcm would use to command the solenoid to function? If so wouldn't that prove my wiring and solenoid to be okay? Also this would point the problem directly @ the tcm. I am going to swap tcms with a buddy and test my theory but any insight appreciative. If this doesn't work I will hook up a dvom to signal wire before it goes into connector and see what I am getting.
Exactly what parameters need to be met in order for the tcm to issue the lockup command? Is this throttle position and rpm or psi or?
Well I have a strong feeling my converter was the issue of not locking up. I have a very loose converter and while scanning turbine rpm and output shaft rpm there is a minimum of 550 rpm difference. From what I have learned is that no way the converter will ever lock with this rpm difference unless using a lockup controller. I will be sending the converter back in for inspection and re stall. I also will be buying a new converter. Leaning hard on the Goerend R converter at this point.
If I go with the R converter should I have the billet stator or not? I sled pull about 2-3 events a summer.

Just going thru some old posts and figured I would update this for anyone that may experience similar problem. The converter that I had in the truck was too loose and would not allow lockup to happen. This could have been corrected by simply using the tcm slip inhibit tables and adjusting the max slip from 600 to 1200 rpm. I went another route with a tighter converter but if anyone is going to run a loose converter on a lbz / lmm truck they will need to adjust slip inhibit rpm tables for normal driving and wot lockup to occur. Some run lockup boxes but if you are using only efi this will generally help the no lockup condition with too loose of a converter.
