First and foremost, i'm not very mechanical
a. During winter, i placed the car on 4WD but for some reason it would not engage at all. Mind you, this is Texas and i rarely use 4x4 except if it's icy on the road (no off-roading).
b. while driving on the highway, when i'm anywhere between 50-65, the car acts like it has a hiccup, the RPM needle jumps very so slightly but cant figure out what it is since it doesnt happen when above or below that speed range.
c. Last week i got a service engine soon light. had it checked at autozone and showed code P1870. Which according to them it's a transmission issue. This makes sense since lately when i place it in gear, it'll stay like it's in neutral and then, very slowly, start moving, even though i'm accelerating.
Can someone help please!!!!! i dont want to end up spending $$$ if the car is not worth it anymore. i just spent about $1.5K in replacing the ABS computer and feel that if i keep that pace, i can just buy a newer car and that'll be the monthly payments
