That's really dependent upon where you live. Not just the state, but where in the state.
What one pays for shop labor in Beverly Hills will be quite different from what one pays in a small city in the mid west.

There is a book time accociated with the job, so in theory most shops should quote similar time it will come down to the bill rate an hour as mentioned

I priced one out of a wrecked GX for $1600 with a 90 day warranty. Since I swapped silinoid D, it's been shifting good but I still have to let it warm up I the morning for about 10 minutes for it not to take a while to go into 1st. I'm going to do a drain and refill on my days off and try adding some lube guard. If it doesn't help I'll drive it until it doesn't drive anymore.
 
This is probably a dumb question, but has anyone who has experienced the codes issue had one of those OTT tune jobs after experiencing the codes? I was thinking of having one done, as I have read good reviews on performance improvements from this service, but not if it could further jeopardize my transmission.

Also, as a data point, since I returned to Louisiana from Virginia in December 2024, I have been driving the GX exclusively in sport mode. I have about 1,600 miles on it since my return, and the codes have not returned (knock on wood).

I have an OTT tune. It definitely changes shift points. It might make shifts a bit quicker but if it does it's not enough that I notice it. Quicker shifts would mean less clutch slipping which means less clutch particles in the oil which might help long term. Other than that I don't see how it would affect the valve body either way.

I had them do the least throttle mapping change option. It's still a little abrupt in the first bit of travel for me but it's not as bad as the pedal commander. I prefer a progressive throttle action and feeling for traction vs blasting through.

The throttle mapping and transmission programming changes do wake it up noticeably but there's not actually significantly more power. Which is what their dyno charts show. It's hard for a tune to get much additional power out of a modern non turbo/supercharged engine.
