4E84 Solenoid Valve S1
I've been searching and haven't really found anything like what I'm experiencing. 2009 mini cooper s (all stock) 130,000 miles suddenly got the gear light with exclamation point and transmission won't shift out of 3rd gear? Turn car off about 15 seconds and restart the problem goes away (for a short time) and acts normally. I scanned it and it showed 4E84 Solenoid Valve S1? I drained the fluid yesterday, removed the drain plug and tube and got out just under 5 quarts. It looked dark but didn't smell burned. I replaced it with Valvoline ATF that was JWS-3309 compatible. Took a short drive, about 20 minutes or so and it did it again. My first thought was to replace the S1 solenoid and refill again with clean fluid but I've read where some on here have replaced the valve body and still getting this fault? Any ideas or suggestions?
