Hello Stan, I've been working hard to find a Professional to assist you with your question, but sometimes finding the right Professional can take a little longer than expected.
I wonder whether you're ok with continuing to wait for an answer. If you are, please let me know and I will continue my search. If not, feel free to let me know and I will cancel this question for you.
I'll wait for advice. additional information car has travelled 120K km
I have done as suggested, cable a little bit slack, had a mechanic look at the control iunit but couldn't fault. took a week to get the car out to some steeper hills but still preforming the same, rapid shift down x 2 and car slows to 70 from 100 so dangerous for following irate drivers. Starting to look like VW problem???? what next, am having the auto transmission serviuced with new oil etc.??
