1997 sierra automatic to manual conversion
 

Well first off i had a slow leak in a tranny cooling line and it got low on fluid and it will run in first and second gear just fine then when it is time to shift up to third it will just rev and will not accelerate. I was wondering what i would be facing trying to fix that problem or if i was going to have to replace the transmission anyhow if i were to change it to manual what all i would have to do
