B&M Shift Plus Issues

[Philbar71]

So I hooked up my shiftplus finally and it works exactly like it should, but only for a very short time.

When in stage one, it works beautifully anywhere from 3 to 15 minuets before the trac off light comes on and the trans shifts as hard as possible (like it would in stage two) ive tried turning it on with the car off and while driving. All to no avail. Trac Off also comes on if the engine is cold or if I manually shift through the gears using the shifter.

Also a few times when I had the B&M in stage one and the trac off light came on the trans wouldnt shift any higher than 2nd. I had to turn the b&m off and turn the car off to get the trans working properly.

Anybody know what the deal with this is? Is my trans on its way out...?
