Ok guys got my transmission together and now I am having an small issue.
The transmission seems to shift fine from 1-2 but 2-3rd has a 300 rpm jump up before it engages. Any idea how to fix?

 

adjust the shift cable on the under side of the throttle body its hard to explain on here if u take it to any shop they can show u how to do it it takes 5 min and if it fixed it then it dose it again in a few days u need to replace the cable and lock on the cable cost like 200 hundered dollars easy to do
