2009 Nissan GT-R: 9-12 Month Transmission Calibration
April 23, 2009
As Mike Schmidt mentioned yesterday, our 2009 Nissan GT-R went straight from the body shop to Nissan of Santa Monica for service.
No, it wasn't broken again, it was just that Tuesday 4-21-09 was the first day our GT-R was eligible to have the transmission recalibrated under warranty. Nissan wants one calibration done at the 1,000-mile mark. We hit 1,000 miles somewhere in the middle of the country while bringing our GT-R back from Tennessee. That service was done at about 3,900 miles and remains the cheapest service we've had to date; they didn't have pricing available yet. But the next service is not based on mileage. Instead they mandate a transmission recalibration be done between the 9 and 12-month mark. Our GT-R, according to the computers at Nissan, started its service life on 7-21-08. Tuesday was nine-months to the day.
The transmission recalibration took a day and there was no charge. Before the calibration, first gear would bite suddenly somewhere around 1,500rpm. Creeping, backing and parking weren't easy, but they weren't as bad as in say, our single-clutch 2008 Audi R8 or Smart fortwo. Now, after recalibration the clutches start to grab around 1,100 rpm and gradually increase force as the revs build. It feels like a normal car now. For now.
The clutches get themselves out of line with miles and driver vigor, not time. Why this is a calendar-based maintenance and not a mileage one is beyond us.
Also included with this 9-12 month service is an alignment. We got the performance alignment because it's a GT-R. Tire life will be reduced. We're okay with that.
