Thread: 2000 GTP - gears 3 & 4 gone

These transmissions typically range in the $1200-$2500 plus installation and that can vary from $400-$800 on the average. Sometimes guys come across a shop that is a bit cheaper but these shops arent doing a full rebuild with all the parts that really should be replaced. $1500 for a 2004R in a G-body sounds aweful high but it may be your area. At the old trans shop I worked at a stock rebuild on a 2004R went for $450-$600 plus $150 for install and that is about the average in town, or was 8 years ago but prices really havent gone up on transmissions around here.
