Hi my name is***** will be glad to try to help. Is the transmission throwing any fault codes? Also, A clunk could be anywhere in the driveline or even radiate through from the rear end as well. Check all your u joints and driveline and suspension components for worn pins and bushings, slip yokes and yokes at the transmission and rears, etc. Drain the oil and look for metal inside the transmission or rears indicating an internal problem. Let me know the results.
