98 Cirrus Tranny problems during winter
 

Hey guys, can anyone help me clear this situation. When its cold out, I have to let my car warm up before i leave (lol). Even after 30 minutes, my tranny does not always grab. For example, if i park nose first, i can go into reverse but when shifting to drive, i'm not moving. If i back in to my parking, i can leave no problem but as soon as i apply the brakes, boom, tranny does not grab again. Its like if my car as to warm up for 45 minutes for the tranny to be ok. If i drive around for lets say 1 hour, park the car for 3 hours, when i get back up and let it warm up for 5 minutes, no tranny problems. only when it sits in the cold for more than 4 hours. my dad does not seem to know whats wrong as he as always had Dodge and hes never had this problem. Oh, when i have to brake (very tight with the line) because the light is changing and i can't make it, it seems like the tranny goes off its gears. HELP ME PLEASE
