changing the filter on a 1995 Chevy Blazer is the hardest thing to do...if you do not have a lift and/or the right tools, it is very difficult...first, there is a transmission bar/brace that runs right across the pan...that bar has to be removed, the catch is that you have to support the transmission....next, even if you remove the bolts from the transmission pan....you need to remove the exhaust pipe that runs across the front side of the pan....it is very difficult an almost impossible to remove the pan without damaging anything inside that pan....
I have a 1994 S10 Blazer. The problem appears to be the same. The solution is not that difficult.
Jack the transmission tail where the cross-member was and the pain slides out! I used a a bottle jack with a drive up ramp underneath. I already had the filter popped out and down, so I'm not sure if you have to do that first. Now to clean up this mess, reassemble and top up the Transmission Fluid!
