Seeking Advice on ZF 5-Speed Transmission for BMW

I’ve recently come across the ZF 5-speed transmission used in various BMW models, and I’m thinking about either upgrading or possibly swapping it into my project car. I’d love to get some insights from anyone who’s worked with this transmission. Here’s what I’m curious about:

  • Which BMW models have the ZF 5-speed? I know it’s common in the E36 and E46 series. Are there any particular challenges I should be aware of when trying to fit one of these into a different chassis?
  • Adaptation tips: For those who have tackled this job, what should I consider regarding mounts and the driveshaft? Are there any specific parts that make the job easier?

Performance and Upgrades

  • Performance enhancements: What are some recommendations for performance upgrades when it comes to the ZF 5-speed? I’ve heard about different clutch kits and shifters that can improve performance. What is your experience?
  • Comparison with other transmissions: How does the ZF 5-speed stack up against something like the Getrag? I’ve seen mixed opinions and would appreciate any thought-out comparisons.

General Maintenance

  • Maintenance tips: What kind of maintenance does this transmission typically need and how can I ensure it lasts? Are there common issues I should be on the lookout for?

I appreciate any advice or shared experiences you can offer. I’m excited about the possibilities and look forward to the discussion!

I’ve been working on my ZF 5 speed and noticed a grinding noise during downshifts. Any ideas on what might cause this?

It could be due to worn synchros or low transmission fluid. Have you checked those yet?

My ZF 5 speed often has difficulty going into gear. Could this be related to the clutch or the shifter bushings?

Definitely check the clutch first. If it’s not fully disengaging, that can cause all sorts of issues. Shifter bushings are worth a look, too!

Is anyone else experiencing a shudder when accelerating? I think mine might be on its way out.

That could be a sign of a worn clutch or even a bad flywheel. Definitely worth investigating before it gets worse!

I once had a transmission fluid leak that seemed minor until it caused major shifting issues. Has anyone dealt with that?

It seems like many owners overlook regular maintenance. Proper care can keep these trans running smoothly!

I just find it amusing that we love these cars but complain about the same issues! Classic BMW life, right?

Haha, true! We endure these quirks for the love of the brand, don’t we?

I’m excited to see others interested in the ZF 5-speed! For serious upgrades, consider the Getrag 260 as an alternative. It’s often regarded as more robust. Any thoughts?

I second that! The Getrag offers great performance, and parts are relatively easy to find. Just make sure to check compatibility with your car model.

I’ve replaced my ZF with a Tremec T5 before. Not only was it a smoother shift, but I could also handle more power. Highly recommend it if you’re looking for an upgrade that lasts!

That’s great to hear! Power handling is so important. Did you face any installation challenges?

For anyone considering upgrades, look for aftermarket parts that come with warranties. I’ve had positive experiences with the UUC short shifter. Makes the driving experience much better!

I agree, it really does enhance the driving feel! Also, don’t forget to replace the bushings while you’re at it.
