The fix-all for all Acura transmissions! - What can I say? I have nothing but praise for this stuff. I bought my 2004 Acura TL in August and really haven't been able to enjoy it since then because a week after my purchase, I was told by a small shop that my transmission was on its way out. I've been babying the car since then, and keeping my fingers crossed during the several 250 mile trips I've made to my hometown. I didn't have many symptoms, except the occasional chatter, RPM fluctuation, etc. I narrowed it down to the torque converter, then did some research. After replacing the 3rd and 4th gear pressure switches and noticing a little difference, I decided to do more research. Then I heard about this stuff... Oh man, was it ever worth the $130 investment! I first got the car jacked up, and loosened the drain. I'm not kidding, I don't think my fluid has been changed in the 107,000 miles on the car. It was pretty dark, and although there was no "sludge," I wasn't happy with the consistency of the old fluid. I spent a couple hours doing the 3x3 fluid change. First of all, it's a comforting feeling knowing I've got clean, fresh, red fluid in there. Secondly, HOLY CRAP! The car drives like it's brand new! No more "gear guessing" or chatter or anything! Shifts are smooth, clean, crisp, etc. I didn't realize how sloppy the shifts had become until I replaced the fluid with this stuff. If you're even contemplating trying this stuff out, DO IT! Thank you, Red Line, for allowing me to begin enjoying my dream car!!! Review: Best stuff you can get for gm auto’s - This is by far the best thing you can do for a 4l60e, 700r4, 4l65e, 4l80e. It just works wonders with the standard in truck transmissions. I was seriously about to go have the tranny rebuilt. I’ve had 3 rebuilt all around the 175k-200k mark. My Tahoe was banging into 2nd and not pulling great in 3-4. Changed filter(every 50k miles for my trucks) and emptied through radiator. Refilled with redline d4 and drove it. Banged into 2nd 1 last time on the test drive and I tell you it now shifts like new. I have a rebuilt tranny in 2 other 4l60’s (1 with about 400k on truck, 125k on trans) and I emptied both and added the redline. I don’t normally write these long winding reviews but this stuff is awesome. Trans runs 20 degrees cooler on stock cooler, shifts like a dream, pulls like it was new. I know it’ll eventually run out of clutch material but I’ll be danged if I didn’t see a huge improvement from the jump. Didn’t have to join some club to buy it either. ## Features - EXCELLENT - gear and synchro protection, balanced slipperiness for easier shifting in cold climates - ALSO USED WITH - manual transmissions and transaxles like T-5, T-45, T-56 and late-model BMW, provides a GL-4 level of gear protection - MOST VERSATILE ATF - use where Dexron III, Dexron II, Mercon and Mercon V fluids are recommended, for use in automatic, manual transmissions and power steering - POPULAR TRANSMISSION FLUID FOR - Toyota Type T-III and T-IV, Honda ATF-Z1, Nissan Matic D, J & K, Diamond SP-II, SP-III, Mazda ATF M-V, most BMW and Audi/VW automatic transmissions - WHY RED LINE - Established in 1979, Red Line Products perform & protect better than any on the market.

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 ### ⭐⭐⭐⭐⭐ Amazing stuff!
