I would say that is normal. At my shop, we usually try to make sure the vehicle is 100% before giving it back to the customer. There's nothing worse than driving the car for three miles and then handing it back to the customer and then theres a problem during the fifth mile. After a rebuild, we keep cars overnight to verify that there are no leaks and so that we are able to drive them cold the next morning. As far as programming, a full day sounds reasonable, but not overnight.Doesn't make sense to me. If they replaced the TCM, I think they would need to reprogram to VIN match, but that should be quick. Besides that, they can do the fast adapt learn procedure which takes maybe 5-10 minutes. Maybe they are charging you to drive the car around all day to learn the shifts the slow way?
More than likely you are correct, and they are probably sending it out to be done.He gave me the full price out the door. about 2450. it went up from 2100 since the entire valve body was replaced. i heard that the tcm is in the valve body. my inkling is they did not have the correct tool to reprogram the valve body and are scurrying to get one. i am allowing them slack and not questioning them. i am going with the flow to maintain a good working relationship with them.
