I have an automatic 2006 Nissan Altima and am having what I assume is a transmission issue.
When I have not recently been driving, my car is slow to shift into 4th gear. Normally it will shift and I will be around 1400 or 1500rpm when I'm going 35, but when I am first driving, I will be around 2300rpm for maybe around half a mile before it shifts and I drop back down to around 1500. Once it has made the shift once though, it is perfectly fine for the rest of that drive.
Anybody know what would be causing this? Is this something fixable without having to replace the transmission, or is that a sign of overall wear on the transmission?
