Hi, My car is 1990 BMW E34 M20B20 that uses 4HP22 transmission and here is the problem: When I put it from P into R it makes a sound like a hitting and doesn’t move but you can understand it is on load, because when I step on the gas, engine cannot outrun 2000 rpm (even at trying to rev). When I shift into N, it starts to move forward and it’s drivable but not an engaged drive, and while traveling or not, when I shift from N into D, it retrieves the engaged drive and goes normal. I think it cannot leave 1st gear or all forward clutches. What the problem could be? Sorry for my English, And thanks for help all given in advance. ---

300K kilometers. 🙂 around 185K miles I think. Its ATF was changed with Dexron 3 and made dry fill, and also filter changed about 10K km ago. ---

This guy found a dirty screen and it fixed his problems , which sound exactly like your problem. He even has pics of the screen filter. > **[Automatic Transmission Shifting Issues - Page 2](http://www.bimmerforums.com/forum/showthread.php?1908147-Automatic-Transmission-Shifting-Issues/page2&s=365eb7325310450433b14f8db794096f)** > > Bimmerforums - The Ultimate BMW Forum ---

So, let me get this straight, I am gonna take down epc solenoid and shift solenoids, and I am gonna either replace or clean them. Am I right? 🙂 Mine can shift 1-2 (bumpy though), 2-3 and 3-4. It seems it is in first gear (or any forward clutch) even if it can shift truly into P R or N (it is my hypothesis :neutral: ) Changing solenoids might not be a solution I think. I have read the conversation and I might have missed some part because of my unsatisfactory English. ---

It goes fwd in both reverse and neutral. It goes into park just fine. The fluid is full and not burnt. It will drive forward when in reverse and in neutral. I turned the engine... Could be an linkage issue for me too? ---

I disattached the battery cables and after a few hours I attached them and I don’t know the reason why I did that, after I shift into all of gears, it got well, but it might be coincidence I think. I hope it won’t repeat again.
