Hey bp, do you have access to the procedure I need on this 97 buick century 3.1 to remove the bellhousing and replace the 1-2 and 3-4 solonoids? Or is my best option an alldata thing? I've replaced solonoids on the older 80's front wheel drives and wasn't too bad of a job but this one looks to be very time consuming. The bellhousing gasket is pricey as well. thanks for any advice bp!!
