흠.. 딜러얘기를 들으니 또 헷갈리는군요.
D 에서 1단 안걸리고 M으로 1단 움직이면 D로 돌려도 1단 포함 모두 잘 작동한다 (엔진 끌때까지)?
스캐너 에러코드 없으면 speed sensor와 inhibitor switch는 문제가 없어 보이고..
계기판의 기어 포지션 표시는, 아마도 미션(TCM)에서 미션 내부상황을 받아 오는 거겟죠? (기어봉 주변의 스위치같은게 아니라).. 그럼 링크 케이블은 정상 위치에 있을거 같은데…
비슷한 D에서 1단 안걸리는 경우 찾았습니다.

차 주인::
가끔 D 에서 기어가 N인것 처럼 엔진회전만 한다. 엔진 껏다 다시 시도 여러번 하면 된다.
Sometimes when I am backing out of my garage in the morning
and change gears from R to D then step on the gas, the car revs as if it’s in neutral.
I have to put it in park, turn it off, restart it, then try to shift into D again.
Sometimes I have to do this multiple times before the car successfully “catches” into drive and I can then drive normally. Yesterday morning I was desperately turning it off and turning it on for a good 10 minutes before I could get it into D. (The gear shifter is in D but the car doesn’t behave as if it’s in D, it behaves as if it’s in N.)
This happened for the first time last summer then did not happen for many months, then it started happening maybe once every other month, now it is much more frequent. The car has been to the dealership once before for this problem and they basically told me to pound sand because they could not reproduce it. I took it back to the shop this morning and they gave me the same “we’ll try” song and dance.
다른이의 권고:: 링크 케이블 유격이 있나 확인해보고 위치를 조정해봐라
Your problem sounds more like a shift linkage problem. You move the lever in the console to “D” and expect the cables/linkage to move the selector shaft in the transmission to match. I believe the cable/linkage is not moving the transmission selector to the proper location. This would cause your problem. You’ll have to follow the cables to the transmission to find the selector shaft. You can move it manually. DON’T move it with the engine running. ONLY move it with engine off. You should be able to place the console lever in “D”, go under the hood and locate the selector shaft, see if you can wiggle it. There are dentents for each console position. If you wiggle the shaft and it moves a little into a detent I believe your linkage needs adjusted. The cable/linkage at the trans selector shaft may have a threaded adjustment shaft, it may not. The cable/linkage at the console lever may have a threaded adjustment shaft, maybe not. You’ll have to locate the adjustable links and trim them accordingly. Once you do this it should resolve the trans problem.
차 주인:: 딜러에서 말하길 트렁크안의 접지 전선을 잘 고정하니 고쳐졌다…?!?
(트렁크 안에 무슨 접지선이 있을까요… 보통 배터리의 마이너스 단자에서 전선이 나와 배터리 근처 차체에 나사로 조여 접지를 하는건데.. ??? 멀티미터 저항측정으로 맞추고 배터리의 마이너스단자와 트랜스미션 쇳덩이의 저항을 재보고 1~5 ohm 정도로 낮은지 확인. 또는, 멀티미터 DC전압으로 마추고, 배터리 플러스와 배터리 마이너스의 전압이 배터리 플러스와 미션 쇳덩이의 전압과 거의 같은지 확인 해 보면 차체의 접지 연결 이상은 확인가능하겟죠)
The dealership says they have figured out what the problem is,
some ground wire in the trunk that was not attached properly and was causing the problem.
They said they have fixed it and the problem should not occur again;
저라면 아래 같은걸 해볼거 같아요.
1. 배터리케이블 5분간 뺏다 끼움. (미션의 운전습관 학습내용 reset)
2. 기어봉 아래쪽 분해 해 보고, 관령 전선 커넥터 핀이 녹슬거나 이물질 있나 확인.
3. 미션 쉬프트 케이블 링크 유격있나 확인 (엔진 끈 상태에서 만져봐야 차가 움직이지 않겟죠)
4. ECM & TCM(트랜스미션 콘트롤 모듈) ROM 업데이트 해봄. (이건 아예 1단이 안들어가는 증상과는 거리가 좀 있지만 혹시나 해볼라면…딜러에서 $100+쯤)
