727 Installed - No Movement in Gears

Final resolution: I had the rear servo installed incorrectly. Everything is back together and driving nicely, reverse too!

It actually shifts a little too firm for my liking, but I think I just need to get used to it. Next time I have the pan off, I will add the accumulator spring back in, although I have heard that it won't affect anything, it can't hurt.

Thanks everyone!
