Make a few tight turns in a parking lot to be sure there's no clunking or binding in the rear and you should be fine. I'd recommend asking the dealer to drain and refill the differential with fresh synthetic fluid and a bottle of "friction modifier" (all parts departments have it) just to start with fresh fluid back there.
As far as the transmission, I haven't seen too many of those replaced, but cars are made by humans and some just break. As long as the new transmission is acting properly, I'd consider it a bonus (new tranny!  )
Thanks for valuing my advice, and if you have any other questions relating to the car or the purchase then let me know!  |
Hi Tony,
The dealer said the trans had a vibration in 6th at 70 mph. I spoke to the previous owner and he said he had not noticed it so it must have been pretty minor. I test drove it yesterday, bought it this morning and I pick it up Monday. I'm not a "clutch-dropper" so hopefully I won't have any diff issues. The car appears to be a perfect blend of performance, luxury, and 4-door convenience. Thanks for you help.
Chuck
