I have a 92 ranger 4.0 with an automatic. Last week transmission started acting up. When the tranny is cold it will not shift into drive. Works fine in first and second but it acts like it is in nuteral rather then drive. Once it gets wormed up it will shift into drive with no slipping. Every once in a while with the tranny is warm when i stop at a stop sign the tranny will also start out in second gear instead of first.
I have already replaced the tranny filter and rechecked the fluid still full. I have pulled the vacume line at the modulator and it did not have any fluid in it.
