I had a small chirp noise in my Van when it shifts into 4th gear. Took it into United transmissions for a total rebuild. First rebuild had the same noise so they did it again and it came back with the same noise.at that point they gave me my $2500. Back and said they don’t know what it is. I can find no one in this state that will rebuild the Tranny. I an in NM any one have an idea?
