1999 Cadillac DeVille 4.6L No upshift
Strange problem with this Deville. If you try to accelerate it will stay in 1st gear, rpms go to [...] no upshift and it just hangs there doing 3900 rpms at won't shift or gain any more rpm. Testing a like vehicle, engine will run to 5800 and shift into second...
