t-56 2nd gear issue
 

I have a 97 camaro z28 and i just put it in transmission shop for a second gear issue unjust recently started to have, i went to put it in 2nd and it went it smooth just no catch, lie another neutral. Transmission shop is taking forever to get back to me with price torepair, im not being charged labor because i know the owner. Im getting impatient because i want to know the price to fix. Does anyone know that is wrong with it and hoe.much the part is to repair? Once again it is an lt1 z28 with t56 tranny.
