I have found a Transmission Specialist who after reading my email said;
Hi Keith,
Yes we can help you out on that, you don't need to remove the motor or complete auto. Unfortunately we are currently on holidays as of today and won't be back until after the 27th of jan.
if you can hold off until then let me know and ill book it in.
Hopefully this guy may solve my problem. You comments are appreciated and may well be on the money.
