5r110 first gear problem, please help
 

hey guys in my 5r110, once the fluid warms up, sometimes at a stop sign, or from p/r to drive the truck tends to "bind" in first gear. it feels like the breaks are sticking, the truck wont freely roll forward. i have to hit the gas and it will move, once it shifts out of force its perfectly fine through every gear. it only does this once and awhile when fluids hot. sticking solenoid? any help welcome
seems like as soon as it goes to 1st gear it also turns on reverse????????:humm:
