Review: Highly recommended product - I was very worried when I replaced my gearbox oil. Oil had never changed before in my car. I bought the same time ATF from the same brand and mixed it with this additive. Now almost two years and gearbox still is working well. Highly recommended product. Thank you Liquid Molly for the amazing product.

## Questions & Answers

**Q: Can it be used with febi bilstein 29449 automatic transmission fluid (atf) mb 236.14 ?**
A: I don’t know, but the German manufacturers are very fast at replying. Good luck & Keep well.

**Q: It's made the shifts smoother but also added some general vibration/roughness feeling when driving, any idea why?**
A: have you just added additiv to existing oil or you made oil change as well?
we always reccomend to add additive when change oil and we reccomend to use quality oil as if gearbox oil will be poor quality additive will not help it

### ⭐⭐⭐⭐⭐ Great product.
*by D***K on 8 August 2022*

I have tried 3 cans of another propriety product to try and reduce the gearbox ATF leak, to no avail at all ! One tube of this product seems, so far, to have reduced the leak considerably, to almost none. It may be continuing to soften the seals and perform 100%. Update December 2023 this product has saved me £1000's as the gearbox has completely stoped leaking over the last year, it is a amazing product, thank you....
