Hi All,

I've got a 1995 Bonneville with about 135k on it. I bought it used around 80k. As far as I know, it has the original transmission fluid in it.

I'm thinking about trying to follow this procedure to change the transmission fluid. I don't just mean a drop the pan and drain routine, if you read this procedure you can see it has you pumping out 90% or more of the old fluid.

I'm curious if anyone here has done this sort of change before, and if so, if you have any thoughts or recommendations on how to proceed? Similarly, I'm curious if anyone thinks this is a bad idea. I'd rather not kill my car :-)
