I just had a new trans put in and i dont like how it shifts at all now. when i fisrt picked it up from the shop it was shifting great but now when shifting into 3 it seems like the tranny totally disconnects from the engine. the engine revs up and then it will go into gear. I dont think that it should be doing this should it???? I want it to have nice firm shifts. Is there a way that the tranny shop can adjust this with out another rebuild???????????
