Lately I've been having some problems with my AODE shifting on my 94GT. When it's cold the tranny has problems shifting into 3rd gear, it'll rev up 1k more then back down 1k. Sometimes it'll also do it around 50 or 60 mph when everything is at normal running temp. Whenever it does this there's a loss of power and the tranny won't shift up but actually shifts down. Any ideas on what it could be? Thanks.
