Jetta Trans code DLZ vrs CLK

[njkid]

Need to replace my tranny on a 1999 Jetta 2.0 114,000 miles. Had my son pick up a used one from a local salvage yard. My tranny code is a DLK and the salvage guy said the one I bought will work fine. His is a CLK code. I am ready to put it in but am holding off until maybe someone knows this is not a compatible tranny. I don't want to have to do the work twice. I do know I also have to use special tranny fluid. I found a brand on line that says it is used in my car. Does anyone know if this is the right stuff, Pentosin Tranny Fluid Part Number Z8001-87949. Thanks for any info concerning this tranny install.
