I blew the front main seal on my transmission and I replaced it. The transmission worked fine before the seal blew.

Good afternoon,

Did all the fluid leak out when the seal failed?

Did you change the filter in the pan?

If it does not move, you may have a front pump failure or torque converter failure.

Change the filter and add new fluid and see if it moves.
