Please give me some advice and assistance on this one.
Here is what I have:
1999 Sentra Automatic wtih 84K miles. The tranmission fluid is at the right level and the right color.
The engine was recently changed and a transmission problem began.
If I start out in Drive, it will not shift from 1st to 2nd until 22 MPH--this is way too late and the car jerks into 2nd. The 2-3 shift is perfect.
But, if I shift the car manually from 1st to 2nd, it shifts perfectly.
What could be wrong and how would I fix this?
Thank you in advance for any help you can give.
