I have a 1992 Explorer, and recently when I first start it and drive the tranny wont shift to 1st gear until it has warmed up, then it will shift fine. I replaced the modular valve on the tranny, the tranny screen and the fluid and it is still doing it. Any ideas.
Try some Lucas Transmission Fix if that doesn't fix it looks like a bigger issue that an Expert will have to look at.
Ty I will try that.
