PWM Frequencies - Any ideas?

Anyone know what the pulse width frequencies are for all of the PWM solenoids in a 1998 4T65E? Are they the same for all years, and are they the same for a 4T60E, or even the 4T40/45E?

I found the TCC duty cycle on a 4T60E at 32 Hz. Mine was set at 68 Hz. It's now at 24 Hz and TCC lock is finally smooth! No more lookin like I can't shift into second gear with a 5 speed! lol
