My tranny was not good and they said they could handle it. Now 7 weeks later they are saying it's not the T 89 BW they thought it was? The parts they are ordering are not fitting and they think it's been modified in some way to work with the 327 engine.I am totally confused and I think they are too.Why is this so confusing for them? Any thoughts would be appreciated. Thanks
