So i call up my local Infiniti dealership to get a transmission fluid flush and a brake flush for my G37, the guy over the phone quoted me $600!! $600 ****ing dollars. The guy had to be out of his mind trying to quote that much for that, i hung up the phone immediately. Called up my local Nissan Dealership and they quoted me $330 for both the brake fluid and Transmission flush, i felt like that was more reasonable and set up the appointment. Is $330 a good price for both the brake fluid and Tranny flush?

 

Brake fluid is a pretty simple DIY, but if you just don't want to deal with that then combined w/ the AT flush that isn't too crazy. I would ask if the AT flush is a true flush or just a drain & fill. If it's just a drain & fill that would be too much IMO.
The factory service manual requires a 3x drain & fill for a complete service, so if that's what they do that would be fair, or a pressurized flush (which I haven't read any FSM procedure for that)

 

I'm pretty sure they guy told me its only a drain and fill.

 

nissan put out a bulletin years ago to dealers not to perform flushes

 

I had my transmission flushed at an Infiniti dealer last year for about $240-$270. I asked specifically how much fluid would be replaced and how they do it. They hooked into the transmission cooler lines and are able to replace about 90% of the fluid this way. I plan to get it done one more time before I leave CA and go back to FL.
