TRANSMISSION HELP!? 97 Ranger 4.0 4x4
when i first bought my truck my transmission was throwing a code, it said something manufatured transmission control. i looked in some fourms and found out it mite me the tcc sensor (torque convert control sensor) so i got one off transmission parts usa, put it in doesn't the same thing. my truck shifts fine for about 15 miles then it starts shifting hard an sloppy, stop restart shifts fine again for say 15 more. so....just got done doing an intake gasket, i have done alot on this truck it keeps disapointing me :( anyways, now trans. in the morning takes a min it before the truck has a enought "pressure" as i would assume to move. it's like neutral then bang it slips in. then when i go to stop at a lite it shifts 1 to 2 back an forth my rpm gauge bounces. only when it's at a creep. any suggestions? pump,torqe converter? don't know STUMPED HELP!
