Would not consider one of these transmissions because you are dealing long distance. That adds freight two ways to the cost on the initial purchase. You are now over $1500 and if you did not hold your mouth right they get to keep your core deposit. Now then you are at $2000. Do they know all the factory engineering changes made in the NV4500 since its inception. Probably not. So they repair to 1995 or 1996, etc, standards with a few innovations they have discovered usually to lessen their cost. If you have a warranty failure (warraty period not very long) you now have another $500 in freight. You assume almost all the financial risk with one of these transmissions for an apparent cheap up front cost.
