hi guys, im new to the site although i have been lurking around for a few weeks. but i have a question as to weather a t case from a 98 yukon will bolt up to a trans from a 89 sierra? i am going to put the powertrain from the 89 into the 98, since the 98 engine harness is butchered and doesnt have a motor and the trans is junk but want to keep the push button case instead if haveing to cut a hole in the floor.
