well, this hasn't really been a BIG issue for me, but i want to make sure it's not a big issue that just hasn't "blossomed" yet...every now and then, for no apparant reason, my van shifts firm as hell. at first i thought it was the tranny getting too hot, but as soon as i turned it off and back on, it shifted normal. it just randomly will shift firm and then normal again...no lights come on or anything. it just made a 5,200 mile trip (to Seattle and back to Arkansas) with no problem except for the occasional hard shift...anyone got any ideas? i kinda figure it's a computer issue, but i don't know if i'm losing a solenoid or if the tranny ECM is fried or if its an internal tranny issue...any help appreciated!
