hi guys. so heres the deal... tranny used to mess up in 2nd, it would shift fine but pop out under load, so i got a complete used tranny out of an 03 and put that in, then everything worked great except i couldnt get it to sift into 4th when drag racing or under load, it shifts fine when im just cruisin if i use the clutch or dont. so i took it all appart again and put the shift forks and drum from the first tranny(even though everything was good and straight) and it was a littile better but it still does the same thing. i cant see anything wrong with it. i guess i just dont know what to look for, any ideas or advice would be great. im tired of the trial and error what am i missing? ive already done the star and shaft mods, what else could i do while its appart, cut the dogs? thanks in advance
