Idemitsu ATF Type H-Plus Automatic Transmission Fluid - 1QT

Expensive, but best possible transmission fluid for Honda Automatic Transmissions. For reference, I drive a 2002 Honda Accord V6. The 6th generation Accords, especially the V6 options, are notorious for failures. This is mostly caused by heat and poor adhesives on the clutch pack material, leading to slipping and poor shifting. The original ATF was Z1, then replaced by DW-1 by Honda later. Both were manufactured by Idemitsu. Now, my ATF was very old when I got the car, so dark I thought it was engine oil when it leaked because it was so black. The recommended fix for this is to replace the ATF in a 3-replace pattern, with a full drain and fill, followed by some driving and shifting to allow the ATF to flow everywhere, and replace it twice more. This will replace almost all the ATF. Due to cost, I was using Valvoline’s Maxlife ATF, which performed quite well, but there wasn’t much to help the transmission. Some additives helped, but only Lubegard’s Red and Instant Shudder Fix products. One day, on the V6Performance.net forums, I found this Idemitsu Type-H recommendation and decided it was worth it. After all, if Idemitsu created Honda’s OEM, surely they know what they’re doing. So, I’ve been driving on this for the past 6 months, and have so far been shocked by the consistent reliability. Before, shifting from 1st to 2nd was incredibly rough, and worse from 2nd to 1st. Park to reverse was bad too, making the entire car lurch. Beyond that, the RPM required to speed up was much higher than it was supposed to be, leading to lost power and higher ATF temperatures. Now, it almost feels like a new transmission! It’s not perfect, there’s still some hitching in the shifts, but it’s not nearly as bad as it was, even with all new ATF, and once it’s warmed up, sometimes shifting is invisible. Going from wondering how soon I have to buy a new transmission to realizing I can cost for probably at least a few more years is an incredible change. Highly recommended!

Good stuff

Been using this stuff for years with my Hondas & Acuras, with a total of nearly 300k in smooth shifting miles. No problems whatsoever...Please make sure you change those 3rd or 4th pressure switches & add a magnetic filter, while wiping clean the drain bolt if you have a 6 speed before you blame the fluid. This stuff is top notch, easy to change, & does a fantastic job of adding shift quality back to all transmissions that need it. We also use the Toyota version in my daughter's vehicle.

I recently had the automatic transmission fluid changed in my 2007 Acura RDX, and I couldn’t be more pleased with the results! As a vehicle owner, I understand the importance of regular maintenance, and this fluid change was long overdue. First off, the process was smooth and straightforward. I took my RDX to a trusted mechanic who specializes in Honda and Acura vehicles. They used Idemitsu ATF Type-H Plus, which is specifically recommended for my model. I appreciated their attention to detail and the quality of the fluid they used, ensuring that my transmission would perform optimally. After the fluid change, I immediately noticed a difference in how my RDX shifted gears. The transitions are now smoother and more responsive, which makes for a much more enjoyable driving experience. The engine feels more powerful, and I can tell that the transmission is operating more efficiently. Additionally, I feel more confident knowing that I’ve taken a proactive step in maintaining my vehicle. Regular fluid changes can significantly extend the life of the transmission, and I’m glad to have done this before any potential issues arise. Overall, I highly recommend getting the transmission fluid changed if you haven’t done so recently. It’s a relatively simple maintenance task that can make a world of difference in performance. My 2007 Acura RDX feels revitalized, and I’m excited to hit the road with renewed confidence!

It's very good; it worked really well for my car. I love it.

Used the whole 5 quarts on a couple drain and fills for my 2011 accord 2.4l. Transmission is working fine so far after a couple hundred miles.

Same and cheaper than Honda oil

Fixed my transmission from hard shifting

Seems great. The shame of it is if you change your transmission fluid at home and don’t have a flushing machine you have to waste some of this fluid during a 3 stage change process. No biggie. The old car shifts gear nicely and is good for another 100,000 kms.

Works fine on a Honda Odyssey EX 2014

J’ai utilisé pour mon Civic 2012, après un mois, toujours pas de problème. Le changement de vitesse est vraiment rendu en douceur. Satisfait à 100%.
