Another Transmission Issue

I am asking a bunch of questions because I am experiencing the same issues and I am documenting a bunch of stuff to see what I come up with. I have been in contact with ZF engineers with hopes of a solution. It appears BMW, Audi, Range Rover along with Jaguar are experiencing the same thing with the same results. I am about to remove my TCM and have it tested so understand I am not trying to give anyone a hard time just want to gather information.

Yes, Please search for a thread by a guy named CCC. Great pictures and very good explanation of the fluid change. Shows all the items needed for a change and where to get them for a good price.
I used that thread to purchase all the parts/fluid and then had my local Jaguar dealer do the change and re-flash the TCM.

I thought I was on to something with the battery voltage but after a full charge on my car I still had the problem today. I am on a mission to find out why this is taking place. I will continue to post as I go along but for right now I have no solution. I hope it does not take me as long as it did on the hyd hose.

I do not know all the answers to your questions but I have been working on this for a good period of time. Yes both 5HP & 6HP have similar problems. I have been in contact with ZF and was planning to call them again once I gather a little more info I do not like to go forward without all the info I need. As for the TCM & ECM I do not have all the info but that is what this fact finding mission is about. I do know that ZF was leaning towards a command/signal issue at this point I myself am not sure that is the case.
