So for the last week I have been having this repeated problem with my tranny. At slow speeds, such as in light traffic, the car downshifts very rough into first gear...seems to be grinding...but more accurately describing it would be to say it feels like when you downshift in a manual too early into first and the car jolts hard. It is happening more and more now and the manual says I should never have to check fluid levels. The car does not have a leak or drip in the differential. Any ideas?
BTW, my car is an automatic.
