97 blazer. 2 door 4 wheel drive. 146000 miles. it ran fine all day. parked it for a hour. took off again. ran fine then as i came to a stop it took off as if it was in a high gear & didnt want to shift. no signs all day. ran fine. fluid full. i let it sit for a couple hours. looked under the truck. i noticed the read differental was leaking some green looking fluid where the drive shaft goes in. not sure if that has to do anything with it not wanting to shift. i took it for a 20 min drive. it ran fine. shifted fine. as i was headed home it started not wantin to shift again. now it seems to only do this after the truck is warmed up. runs fine shifts fine till warmed up. what can my problem be? is the tranny going out?

i had a scanner on it. only code that poped up was 3-2 soilinod. someone told me sounds like its in limp in mode. its like it doesnt want to down shift.
