transmission shift too early?

I have a 78 Pontiac firebird with a Chevy 350, from a stop if i give the gas full throttle the car will shift from 1-2 gear at around 10-15 mph, but i can down shift the car manually and hit, well i guess about 40 -50 mph before i have to shift to second. What can i do about the early shift so i don't have to manually shift the car all the time when trying to run it? What could be wrong with it? Thank you.

HEY CURTIS: I had that exact same problem in my 350TH after I put in a shift kit. What happened was one of the little check balls moved during installation and got in the wrong flow channel. I discovered it when I upgraded to a Transco Auto/Manual shift kit from Sumitt Racing for about $ 70.00. My sugestion would be to recheck installation of shift kit. I hope this helps....DAVE

HEY BLACK: THe Transco kit was great! It came with all color coded parts, video, instruction book, tech line. It works great and solved quick shift problem. It was about $ 60.00 at Sumitt Racing. You can use it as a manual or automatic shifter.....DAVE
