Ok, just got a 1997 explorer sport (4.0) and was warned it has some shifting issues but not all the time. So yesterday it was shifting fine then all the sudden after i had been driving awhile it was a B!tch to get into first when at a complete stop (stick) so when i got to another stop i tested and it was a b1tch going into any gear from a stop, like i had to push really hard to get it to go in, but it didnt grind at all, or kick back out and it always went it, which i would think if the synchros were going that it would grind/kick out but it didnt do any of that. Also it only does it once the vehicle gets hot, and when i shut the vehicle off it goes into every gear fine, without any hesitation.... Any ideas? anybody ever have a problem like this? Havent really dug into it at all just wondering if anybody else ever experienced anything like this.
