Idemitsu ATF Type HP Automatic Transmission Fluid for Subaru - 1QT, Red, (30040099-75000C020)

This is great A/T oil for my 08 Subaru Outback.

OEM supplier, few bucks cheaper than dealer.Not all HP ATF is the same, some others result in shifting hard up or down, especially 2-3 and 2-1. Not so with using this.

TL;DR: works just as intended and IS the manufacturer of the Subaru HP variant. Idemitsu HP is the same. Its what Subaru recommends over Dexron since 2006 for these transmissions.To give a little background: My center lockup clutches (MPT if you know) were binding in turns which often happens in automatic Subarus when the oil gets old or dirty. It feels like a shutter when you make tight turns, and you can hear the tires binding up. Its 50/50 that or Duty C solenoid went bad. Need to fix it or risk burning the MPT clutch pack. One of the first things that should be done, even if the oil is dark, is to give it a change. The oil pan holds 5 quarts, the transmission itself holds a total of about 15.Subaru service bulletins state( in 2006) that after '06 they do not recommend Dexron, they recommend Subaru ATF-HP. This is that very same HP formula. Idemitsu makes the blue Subaru bottles of the same stuff but at about half the cost that Subaru sells their blue bottles at.Well, one change is all it took. One change and the MPT broke free within the first tight turn. The transmission never shifted or felt better. No more hard shifts, no more shift hesitation. No more solenoid buzz. no more " idk which gear to choose" syndrome. I will change it 2 more times after periods of about 500 miles to get all of the fluid new, just as many in the community recommends.If you see glitter in your old oil, time to get it rebuilt. I did not and its the only reason why i changed it even though it was dark and didn't re-add some of the old oil back( often done because that glitter is usually clutch material and without it, you will slip gears). No clutch material from any of the MPT or drive gear clutch packs in the oil and no broken teeth in the gears. If this oil change doesn't help with MPT bind, could be your Duty C solenoid but that usually throws a code and makes your ATF TEMP light blink 16 times when you start the car.If its Duty C, you will need more of these as you have to drop the pan and do a little work.

Great seller, fast shipping, will buy again !! Thanks !

Worked great in my 2011 Subaru Outback 3.6R with the 5EAT Automatic Transmission, 180k miles, had to replace a faulty Turbine Speed Sensor, which required me to remove the transmission pan and valve body. I wound up needing roughly 8.5 quarts to refill it and get it back to level after this repair, I only ordered one gallon and regretted it, I should have ordered 2!

Product arrived prompt. Works well to replace transmission fluid

Subaru OEM fluid without dealership markup.

My preference is to stick with what the manufacture recommends in putting into my Subaru. Although there are universal ATF out there that states that it meets ATF Type HP specs, I feel more comfortable in using what the factory put into my 2011 Subaru Outback's transmission from the onset, and Idemitsu ATF Type HP has never proven me wrong. I do a complete ATF fluid change every 30k miles by draining the transmission via the drain plug and also running the engine with the transmission cooler line disconnected and routed into a container to get nearly 100% of the fluid drained and changed to fresh Type HP ATF. My Outback now has over 150k miles with its original transmission, so obviously maintenance is a huge key to longevity. The fluid isn't cheap, but it is exactly what the manufacture recommends without having to go the universal ATF route.
