TCC sliping when in lock up

[nchristian]

I have a 2004 silerado with 4l70E and lq9 6.0l.I have put a
10 inch,2500 stall. It is a midwest converter. Im get about up to a 200 rpm slip when going about 50mph when lightly accel.(like going up a hill).the slip is causing a vinration noise.(this is the 2nd converter).I was needing a little help. Is there anything i can do to increase the pressure to the tcc or anything else to help with the slip.

the rate at which pressure applied when slipping is adjusted on table {D2905}, you could try increasing those figures so the pressures are increased quicker when slipping is detected.

You could also play with the release speeds so under loading the TCC will release rather than chatter/slip.

Could be the TC is just not capable of handling the load its given.

thanks for the help. I increase the D2905. the slip is below the 50 rmp. pulling a 2000lb boat i my see about 6 rpm slip.

I increase the d2905 to 60 psi/sec.may be a little over kill but no slip
