This is a good product that works on small transmission fluid leaks. Unfortunately my vehicle had a leak that was too large and whilst this helped quite noticeably, it was not a complete fix in my case. It definitely bought me more time before having to pay for an expensive repair. **Q: Can I use on power steering pump** A: unknowing for sure , it might if you use a.f.t in power steering pump **Q: The directions say pour bottle in to Transmission, but then says "one ounce treats one quart of fluid". So do I need 5 oz. or the entire bottle?** A: One ounce per quart of transmission fluid **Q: Could it damage the transmission or other car parts?** A: Sorry can't answer that but it worked in a 56 year old transmission. ## Frequently Bought Together - BlueDevil Products 00236 Transmission Sealer - 16 Ounce - BlueDevil Products 49499 Oil Stop Leak - 8 Ounce - BlueDevil Products 00234 Rear Main Sealer - 8 Ounce --- ## 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.es/products/8963642-bluedevil-products-transmission-sealer-16-oz-seals-leaks-in-automatic](https://www.desertcart.es/products/8963642-bluedevil-products-transmission-sealer-16-oz-seals-leaks-in-automatic) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-08-13*
