Slipping automatic transmission

kia
sportage

#1

first gear “surges” and has a very dificult time shifting into 2nd. I do not have a history of the car ( it was my parents, they both passed away at about the same time and we are trying to determine if the car is worth repairing ).


#2
So you don't know when or if the car ever had a transmission fluid change?  

It is time to do a sniff test.  Does the current fluid smell burned? 

What year Sprotage is it and how many miles on it?

#3

Is the tranny fluid level correct. What color does it look like when you wipe it on a white paper towel?
