Engine/Transmission (1998.5 - 2002) Tow-Loc Issue

[WILLD420]

Installed a BD Tow-Loc yesterday. Now whenever it hits overdrive, it downshifts back to drive, the o. d. light comes on and flashes, and the trans goes into limp mode.



This is in the stock setting. The unlock position works just fine and allows all gears. So I'm thinking it must be in the T/C lock portion.



Any ideas?



Thanks.

Got it figured out, now need help with other issues.

I was under the impression that the tow loc was supposed to over ride the factory settings when you have it activated. It does over ride some, but it's still locking the torque converter at 30 mph when I have it set to lock up at 48 mph.
