I have been driving my 89 Camero RS sice 95 and it recently kicked it. 2 Weeks ago I purchased A 95 Millenia from an auction. Yesterday it started slippin really bad, but it is like it is skipping 3rd an thefinal gearso today I changd the tranny filter and fluid,but there is no change. Are there any external plugs for the elctronic tranny that may be loose?? ay other suggestins?? Also, where is the best place to buy used, or rebuilt tranny's? It hasthe 2.5 liter engine

 

I would really appreciate some help with this problem
