I took my journey to the dealership after I heard a strange noise. They sent the transmission mechanic to my car and they drove it 3 miles round trip. Got back and they said no transmission issues were noticed; however, there was a slight whine but they said it wasn't a major issue. Got in the car the next day to go to dinner. The car was fine for about 1.5 miles after leaving my house. All of the sudden when I tried to accelerate it wouldn't I had to rev the engine up just to get it to kick into gear and it wouldn't last (limp mode as they called it). I am highly confused and have been researching quite a bit.
The worker (second trip, not transmission specialist) checked the transmission fluid. He said it was low but "not low enough to cause an issue." They did the codes and it popped up the following:
P1790 (Fault Immediately After Shift)
P0868 (Line Pressure Low)
P0740 (TCC out of range)
Gear ratio error in 2nd, 3rd, & 4th
I understand the codes; however, it seems strange they get these codes and wouldn't even take a look at the transmission. They said it was dead. I am confused as there have been no issues of slipping, no major changes in gas consumption, or any other warning signs. Any tips would be appreciated as they are quoting me 1800-3000 (again, without even doing a full diagnostic).
