727 wont go to drive after speedo gear change

[taxspeaker]

I had the rear end rebuilt and put back the original 3:55 gears. Had to then change to the correct # of teeth on the speedo gear in the tranny. I indexed it and checked fluids after starting and running warmed up in neutral. All fluid levels fine and in test drive speedo is right on the money. However I get a real hard shift 1st to 2nd and then no shift from 2nd to drive. Did I mess up some sprocket or indexing? Any ideas.
Thanks-this is on the Alaska Highway Superbird. 440 stock, 4 barrel, original transmission with only about 10,000 miles on it and no prior issues.

I don't know much about transmissions, but it sounds like a throttle pressure issue. Kickdown linkage and governor control it, and the governor is back where the speedo gear is.

Something I was taught about troubleshooting a long time ago was: If it worked fine before, then maintenance was done, and something crapped out, go back and look at the maintenance done.

If it is a stuck governor, I've read that a quick shift to park and back while moving in gear can free it up.

I'm not an auto transmission guy and do not know.  So I will ask.  Won't shifting into park while moving cause somethings to break?  I thought park was not for moving.

I recommend doing you own research, I'm just parroting what I've read.
As far as damage, the spring loaded parking pawl will try to lock, but won't be able to, and it'll make noise in the process.
This is just momentary into park and right back into drive

Thanks guys-tried that one but did not help. Will just run it to transmission shop

Sounds like throttle pressure rod / linkage is stuck in rearward position

And that right there is why I love this board-fixed, thanks guys. I forgot to hook the springs up.
