I had to go on a mission of mercy tonight when my son's 240 wouldn't get him home from work. It's an auto/AW70 transmission and at first I thought that it was low fluid as it leaks a bit. I checked the level with the car not running and the gauge was dry so I dumped in 2 quarts and then ckecked again (it was a long day) and wamo....lots of fluid now. He has said that it was slipping badly when he tried to drive it but it seemed to be working so we headed for home. We didn't get very far when he pulled to the curb and said it was slipping again and so I drive it and sure enough it slips very badly when it goes into third. 1, 2 and R seemed to work Ok so I told him to try leaving it in 2 and keeping it to about 35. This worked and we made it the 12 miles home. The transmission has always been OK until now, but is this the death rattle? Is there any fault finding i can do or is this just get a new trany time? Any helpful advise would be highly appreciated.

Thanks,

Cliff
