Evedently, this forum sucks. If I had posted the Q on any other forum, it would have been answered by now. (posted 11/18). That's OK, I figured out a temp. fix for the problem. I guess the moderators on this forum are not as schooled as other moderators on other forums. BTW , if you ever have problems with your gauges going dead on ya, just smack the dash with your fist and they will come back on.

Temp fix for a tourqe converter that likes to un-lock at 75+mph and lock-up again is install manual torque converter lock-up switch. Istallation procedure is located on the startup forum under Tech. articals/trans. lockup switch.

 

The mods here are not schooled to solve your problems. Public forums are on the internet for public participation.
Glad you found your solution.
