2nd gear issue?

[4doorboost]

so i pulled my tranny and replaced it cause 2nd gear at high rpm it wouldnt go into gear or grind just would sponge out and car would rev like its in nuetral. put a new (used) tranny in and it felt great for about month now its starting to not go into 2nd at high rpm? all other gears r fine and low to mid rpm goes in fine. doesnt grind at all. could it be dissegnagement issue, wrong fluid, bad adjustment?

well, what fluid are you running? have you tried the static test, Rev on flat ground 1st gear clutch in see if it creeps? Have you done the shifter adjustment?


Or the short answer... Yes.
