: 4T80E Trans neutraling out in Drive/OD

06-16-04, 11:29 PM
Has anyone else had this problem? A trans was built for a 2000 Caddy Deville and now the car does not recognice D or OD as '?' show up when those gears are selected. When it is in D or OD it acts as in neutral. Manual 1st, 2nd, Reverse, and Park all work properly.

Any ideas or anyone have this problem before?

Did you check the PRNDL switch adjustment. The neutral-safety switch on the top of the transmission at the shift cable connection?
