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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent produit ! *by on Reviewed in Canada 6 August 2025* Très bon produit, j'utilise ce produit exclusivement pour ma Corvette C6 depuis longtemps ! ### ⭐⭐⭐⭐⭐ Good *by on Reviewed in the United Kingdom 26 September 2020* Matches 955 Cayenne transfer case fluid specs. ### ⭐⭐⭐⭐⭐ Super *by on Reviewed in Germany 4 March 2018* Ich bin begeistert was der getriebeöl redline d4 atf leistet.
