I have a 94 Taurus with the 3.8 and an AXOD trans. My problem is sometimes the tranny doesnt upshift from 1st to 2nd. The thing will rev to where ever i want it to. But sometimes it doesnt do this. what would cause this problem? :confused:

well, being a '94, you have an AXOD-E, not an AXOD. The problem is probably a simple but expensive to fix parts failure inside the transmission, either a band or a spring probably.

I would try changing the fluid and filter first on the tranny. A clogged filter will cause bad shifts. I like to try the simple ( and cheap ) fixes first.

if your transmission filter is so clogged that it won't shift, then driving it like that will kill your transmission anyway since nothing will get lubrication. Also, for a filter to get that clogged, lots of stuff would have to break off in the trans to clog it, which would also be a sign that this can't be fixed with a simple filter change.

I have changed the trans fluid/filter/gasket already as a schedueled maintence. could it have anything to do with the VSS?
