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. ## Frequently Bought Together - Lucas Oil 10441 Automatic Transmission Fluid Conditioner - 20 Ounce - Lucas Oil 10009 Transmission Fix - 24 Ounce, White - Valvoline Multi-Vehicle ATF Full Synthetic Automatic Transmission Fluid 1 GA --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/228256354-lucas-oil-10441-automatic-transmission-fluid-conditioner-20-oz](https://www.desertcart.sg/products/228256354-lucas-oil-10441-automatic-transmission-fluid-conditioner-20-oz) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-19*
