Transmission itself is great. Could be other things as mentioned here but common issue outside actuators/TCM would be the clutch in the bell housing. Recommend when accelerating from a stop to go heavier on the gas so it engages more hard. Could prob dive it like that for a few years but eventually will gunk up with enough dust inside that the actuators won’t be able to move the forks. Most shops will charge $3,500+ to replace. If you’re good with DIY you can prob do the job when the time comes yourself for about $750 for the Luk repset and dual clutch trans fluid.

Pros: transmission is great

Cons: clutch gunk up with dust

Vehicle: Ford Focus

Never had a problem with them and the last kit I bought was only £60 (and was LUK).

Pros: no problems, good quality

Wouldn’t trust anything but the luk kit at this point. Ur talking maybe $100 difference for something that might be fine be something proven to be oem quality.

Pros: oem quality, proven

Cons: maybe $100 difference

I used an OEM LUK flywheel and upgraded to a 4-puck Sachs clutch.

So, if you just take that flywheel to a machine shop to scuff it up, lathe it down to have a perfect fresh surface, you can just put a new LuK or Sachs clutch kit on it.

Pros: nice and quiet

Cons: makes a horrific racket

Vehicle: Volkswagen Golf

I read somewhere that some aftermarket flywheels (maybe Luk) were manufactured incorrectly and cause problems like the one you have now.

Cons: manufactured incorrectly, cause problems

I had a clutch kit (LUK) put in my 1998 Ranger 2WD back in March 2025. Approximately 10,000 miles ago. Had issues with it recently and took it back to shop. Shop called today and said clutch kit is warrantied but not labor.
