I have a problem with my red brake light and yellow abs light. After starting my engine both lights go on then off like their supposed to. But after I start rolling the car they both come on and stay on. About the same time this started I noticed my transmission wont shift into its highest gear. The car will push 4000 + RPMs to go 55. For some reason the OD wont kick in, I am wondering if the abs/brakes and tranny problem are tied to the same trans and/or speed sensor or are they 2 different problems. ?Thoughts?

A full scan with both a trans function and abs scanner will point you towards what is going on here.

Update: Last night I noticed my cruise control switch was pushed in(on) When I disengaged it both the brake lights went out and the tranny started shifting fine. Weird! Am planning to spend some quality time today to run down the wiring schematic.
I would like to get it scanned but a GM dealer will cost $$$$$ nobody else seems to have a reasonably priced scanner to pull abs codes.
Is there a sensor that is shared by the cruise control and ABS system???

No.
