Several of the 2.5s had that diesel sound. A friend had one back to the dealer many times trying to get it quieted down, but no luck. Last time I saw it it had 140K on it and still running strong.
Look for rebuilt engines on ebay. There was a guy on there that had bought up a bunch of end of production units from a major remanufacturing company and was sellling them for around $300. No warranty. He was advertising them for Buicks, but he had several variations of the 2.5
You can put in a 4t60, but you will have to get different axles
