MINI Cooper S is experiencing issues with the transmission jerking and hesitating, problems with the automatic gearbox? Any repair recommendations?
Hey there, sorry to hear you're having issues with your MINI Cooper S's transmission. Transmission jerking and hesitation, especially in an automatic gearbox, can be a real pain, but there are a few things you can check out before things get worse. First, I’d recommend taking a look at the transmission fluid. If it’s low or looks dirty, that could be your culprit right there. A fluid flush and refill with the right type of fluid, as recommended by MINI, can sometimes make a big difference in how smoothly your gears shift.
Another thing to consider is the transmission solenoid. This little part controls the flow of fluid in the transmission, and if it’s on the fritz, it can cause those annoying jerks and hesitation. Getting a mechanic to test it out and replace it if necessary might just solve your problem. Also, the transmission control module (TCM), which is basically the brain of your gearbox, might need a software update or even a replacement if it's malfunctioning.
If your MINI has seen a lot of miles, it could be that some of the internal components like clutches or bands are worn out. Unfortunately, if that’s the case, you might be looking at a more serious repair or even a transmission rebuild. But before you jump to that conclusion, check for simpler things like vacuum leaks or issues with the throttle position sensor (TPS), as these can also cause similar symptoms and might be a quick fix.
If you’ve gone through these checks and the problem is still there, I’d recommend taking your MINI to a specialist or dealership. They can run a thorough diagnostic and figure out exactly what's going on. Catching transmission issues early is key to preventing more expensive repairs down the road, so it’s worth getting it sorted sooner rather than later. Good luck, and I hope you get your MINI running smoothly again soon!
