TH350 Starts in 3rd

I recently rebuilt a tranny with my cousin and did so with the help of a video. We followed everything on the video. We did take out the middle seal in the first stages of assembly and then plugged the passage with JB weld at the front of the tranny where the pump goes on.

When I start out in 1st gear with the shifter in 1st 2nd or D The truck is is 3rd gear already. it lacks power and stays in 3rd gear. It does not kick down either. I dont know if it is another problem either because the tranny was bad when i got the truck so i never really had a chance to see how it worked before the rebuild.

Any advice or suggestions would be greatly appreciated!

Check the governor for proper operation, I think it may be stuck in the open position.
