I recently got a new stall that is bigger so I have no use for the stall that i took out which is a TCI 3500 which ran strong and has apx 6k miles on it but is in good shape. this was in my 07 Silverado for a 4L60E. i would like 400 OBO or will consider trades for a 5.3 short-block or trade plus cash for a 6.0 short-block let me know.Would like to sell local first I live in the Deer Park/ Pasadena area.
