Lava 0 Report post Posted September 20, 2018 (edited) Hi there, I’m new on this forum. I have a 318i 2002. I’m having a issue in automatic transmission. When I start to drive the car after a cold start, rpm suddenly goes bit higher. Then the transmission error occurs and shifts are becoming hard. Can feel them really hard. However, once I stop the engine and restart the car, this error and hard shifts go away. Car would shift as normally. Does anyone have idea on what could be the issue? Could it be a bad MAF? No check engine light so far. And I did change the transmission fluid and filter as well. But still issue is there. Thanks in advance.

Your normal bluetooth/WiFi to phone type scanner will not do the job as it only talks to the engine computer (DME). Find someone local with INPA set up on a computer or set it up on your own windows computer with it.

If it is a definite trans issue then Ace-o-Matic on Stanmore Road. Quote Share this post Link to post Share on other sites
