Their products are very good. LG Platinum is designed to meet mfg approval specs for ATF without approval codes on a PROPER base ATF fluid. I just did an Auto trans service on a 2000 Jetta TDi.(supposedly sealed and need no service for life) Yeah right. I changed the Trans filter, and pan gasket, and Side Cover gasket. I refilled with 3.5L Ravenol full synth ATF it's already fully compliant ATF with VW specs and still added LG Platinum just to keep things inside good. (seals, valves moving etc.) Tranny has 287K on it, expect to get at least 150K or more out of it now. **Q: Is this compatable with a Honda Accord 2000 LX Automatic Transmission?** A: That transmission should call for ATF Z1. Red Line recommends for this spec, so you shouldn't have a problem with using D4 in your Accord.Here's a link: http://www.redlineoil.com/product.aspx?pid=51&pcid=9 **Q: Can anyone say if I can use this on a mazda 3 2010 model automatic transmission with a manuel overdrive?** A: I'm using Red Line D4 in my 2011 3S 2.5L since 2011 no issues even in low 15 degree temps. ## Frequently Bought Together - Red Line 30504 D4 Synthetic Automatic Transmission Fluid (ATF) - 1 Quart - Red Line 57904 75W90 GL-5 Synthetic Gear Oil for Hypoid Limited Slip Differentials - 1 Quart - Slippery Pete - Fluid Pump for Standard Quart Bottles - 8cc per Pump Stroke and 3rd Hand Adapter, Transfer Gear Oil, Transmission and Differential Fluid (28mm) --- ## 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/3962881-red-line-30504-d4-synthetic-automatic-transmission-fluid-atf-1](https://www.desertcart.sg/products/3962881-red-line-30504-d4-synthetic-automatic-transmission-fluid-atf-1) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-02*
