Can't find any info on this topic .Someone must have some input?????Been a long time since I asked this question. absolutely no replies. Does anyone ever change the transmission filter and fluid in a buick regal after 70 thousand miles. this seems like a TABU question to ask? There must be a way to change these items. No matter what the manuals say the fluid changes after many miles. There is a torx plug on the top of the transmission for a refill. need to know where is the drain plug and Full plug .HELP.
Evidently Transmission fluid and filter changes are for Business Owners to deal with. I:E: Dealerships, Transmission Shops and Professional Mechanics who have Info from places like ALLDATA.Com???? Where the correct INFO is. Can't afford $200.00 a month for Membership.
I found out how to do it. Go to u-tube type in Volvo transmission oil change Aisin TF-80 SC 6 speed auto. This person did a perfect job of how to do it. I followed his video worked perfect. I purchased my fluid from ams oil their product is better than GM'S and Cheaper. I had to do it 3 times to get my fluid to look Reddish color. Started off color like Chocolate Milk. Goes to show you, it Needs Changing. I changed at 80,000 miles. You will need a scan tool for the Tran's Temperature. Great Video.
