I'm guessing that it's either a 14 or 15 mm like most other GM plugs.TMMAR said:I saw in one of the threads that someone indicated the size of the oil drain plug. I can't seem to find it again. Does anyone know the size socket needed to remove the oil drain plug?
"The Internet" was down??? Do they actually download the tranny update over the internet each and everytime they have to do a tranny reflash. Hope our Acadia's do not get a virus during one of these downloads. ;DTMMAR said:Decided not to undertake the challenge at this time so I took it to the dealer for the oil change and I'm glad I did. I had a coupon from the dealer for a $20 oil/filter change and while there had a recall done and tried to have the trans program updated. The internet was down so I have to go back for that but they were giving out coupons for a $20 car wash so it really paid off and I didn't have to mess with the filter problem.
I went into the shop and watched the tech as he was trying to update the tranny. He logged on to GM World website and hooked up a device to the car and to the computer with 2 connectors. He kept getting a message that GM World was down and he could not do the update so I quess that they actually do down load the updated via the internet everytime.
