## Questions & Answers

**Q: Do you have to flush the transmission to  use this,or can l just add this to existing transmission fluid, thanks for the feedback**
A: After 50,000 miles you should change your transmission fluid (and filter unless it's a screen type) if it's still bright red. But If it's very dark red or even worse black then flush the transmission it's money well spent to save your transmission. Keep in mind it will look like red metallic paint that's just part of normal wear. If it's bright red then just drain some transmission fluid to keep it at the proper level. Overfilling an automatic transmission by just a few ounces can cause it to leak. Best of luck to you.

**Q: Does this work on a Prius?**
A: I believe it works on any automatic transmission.  Call Lucas Oil company to make sure and/or Toyota

**Q: he can use on any transmission fluid?**
A: Yes it's compatible with conventional and full synthetic transmission fluids note that this product is not compatible with CVT fluid

**Q: do you have to drain any fluid**
A: Check your fluid levels first, always! If it's full, or close, then drain the appropriate amount. 32oz bottle, drain 32ozs. Keep the old fluid just in case if you do a drain & fill on a trans that hasn't been serviced for 10+ years or over 30k-50k miles. That fluid may contain clutch material that's allowing everything to work properly, and fresh fluids can disrupt the fine fluid friction balance needed for an Auto Trans to work correctly.
