Installed valve, put pan back on and started flush. Couldn’t get out of park. First thought I had screwed something up with the shifter because I had just replaced a cracked plate. Pulled pan. Figured out piston where fits into linkage was crooked (first pic) and jammed against the channel. Second pic shows correctly aligned.

 

Nice catch, and lucky no unintended consequences.

Yes, I also got caught out by that

I did add a caveat to BobRoy's excellent writeup thread for this procedure:

...upside is I got the first trans flush in early

 

Great. I installed mine yesterday and now am worried that I did it incorrectly! And since I'm on jackstands till my new suspension comes in I'll fret for a week!

 

Without out starting car, turn to on and press brake. If can move shifter through right side of J gate did correctly.

 

Success!
