Thanks guys plenty of great advice , once again the forum has given great words of wisdom,
They help for when you go into the shop you do know what you are talking about and dont get bullied into too much money spent in the wrong areas.
The band did go and its a bit of a mess in there and a rebuild was in order

, the costs for this were starting at about $2500.00 Australian (1/2 that in US dollars)
My Mech found another box we checked all items and replaced filters and oil etc. before installation will be ready today . He worked overnight on it and its costing me $1600.00 in total (Australian / thats about 1/2 in US dollars) the box has done about 90,000 kms from what I have already found out thats mighty fine price also.
The mech is in Brunswick in Victoriuan state Australia . He also imports his own parts from the motherland and Lebanon, He's Lebanese and has a guy who I swear has Mercedese self leveling fluid for blood, thats all he works on(Even the factory dealerships aroud give him a call for tricky problems on older cars.
So once again thanks to the many out there

the forum has proven itself yet again with quick responses and sound advice.
Thanks again
Regards
