New member here, but not new to Infiniti's. 2006 G35x..1st) Has anyone ever had the incorrect mileage come up on a VIN# inspection? I purchased this car and it showed 116k on the odometer...on a online VIN# check (after I purchased it) it said it had 341k miles! How could you drive 44,000 miles a year for 8 years? The interior and steering wheel are in pristine condition...2) Has anyone had transmission slipping, won't go into 5th gear except in manual, hesitant shifting kind of thing, but drives ok at highway speeds, where you then replaced the valve body and solenoids and that fixed the problem? How bulletproof are the gearcases? I had a mechanic drop the transmission pan and he said the TCM contacts are fried on one part. I know it needs new solenoids...I've ordered a new valve body w/solenoids off Amazon and going to have a transmission guy install it and program it for $300. Has anyone just replaced this part of the transmission only with success? I can't afford to rebuild the gear case/transmission...let me hear of your experiences...thanks

 

The online vin checker may have been estimating what the mileage should be... I use the free version on carfax.com and it has a mileage estimator because not all shops electronically log the mileage to the carfax database. But you can look at the service records in the carfax logs and get a good idea of close mileage unless it has never been serviced anywhere which is very unlikely.

If your car / transmission has only 116k it may only need a valve body swap. The clutches usually make it to 180k to 250k from what I have seen. If the valve body screwed up in a way that allowed it to slip really bad and it was driven for awhile it could have hurt it.

 

The odometer reading is stored in the instrument cluster. If someone swapped the cluster with a lower mileage one because of something like the notorious fuel gauge failure problem then you can definitely end up with more miles on the chassis that is shown.

There's a pretty massive difference in the parts wear between a 116k and a 341k chassis though. Unless someone has been diligent about replacing bushings and other suspension components it would be pretty obvious when inspecting under the vehicle. There's also no way it would have 341k on the original motor, compression test the engine to see how much life is left on the rings that will tell you a LOT about it's condition.

However the engine may have been replaced as well.

A super high mileage clean chassis is perfectly fine if worn components have been replaced. I've seen quite a few half-million-mile cars that were in pristine condition and ran better than cars with 60k miles on them. I wouldn't worry too much about it.
