My 2024 D Max 2500 shucked the transmission at 29,000 miles and has only had a fifth wheel trailer hooked to it once , mostly pull bumper hitch fertilizer trailers and just daily transportation. Was repaired under warranty, but took six weeks to source a transmission as there are a lot of them with the same problem. Tech who put it in said transmission is not a real Allison automatic.
