Re: Transmission clunk
Most probably the fluid and filters change will solve your problem. Maybe a good idea to put it on a DRB scanner before opening to check for faults codes, just to prevent opening it again. You can then also realtime see the pump linepressure and other inputs, which could show any anomally.
