Chevy & GMC Vans

how long does it take to remove a trans from a 05 awd ? and what is the avg cost to rebuild ?

I found a really clean 05 awd with 155k on it but the trans is bad im debating on buying it if I can get it cheap enough.

the last two Astro transmissions I had done were $1100 and $1300. One was an 1987 and the other was a 1992. Local guy recommended by a friend, picked up and delivered the vans as well.
