Amazon Customer –
Got the package just 3 days after I ordered it. Noticeable improvement in shifting smoothness after replacing my old conventional ATF.
Be careful about spills – the stuff has a really strong odor that takes a long time to go away.
marc majlaton –
Red Line is the best. I flushed the transmission on my 1990 420SEL Mercedes with 8,500 original miles. The car had been sitting since 1992 and all the transmission fluid was bad. The car now shifts like it should.
CJ –
It’s good stuff. I like squirting fluids into holes, and this would fall into that category, pricey yes, but quality. Definitely not to be used as a replacement for baby oil though…..
Will –
Was a bit Leary of the price but man my car shifts smooth now
Macca Ronibut –
I will never use anything else for my 4EAT 2002 Subaru WRX transmission. Getting ready to do a small drain/ 5 quart replacement, to refresh the fluid. About 25k miles on a full 15 quart drain/replacement. Took some time because I would never hook up to a flushing machine(very very bad never allow a mechanic shop flush the trans on your car with a “machine;” it pulls important gunk out of your transmission that is vital in 8+ year old vehicles due to older transmissions having worn down clutch-plates/gears that need that gunk to “hook up.”).
Instead I drained about 5 quarts at a time(that’s all that drains, in my car, because of the torque converter) drove for 200 miles and replaced another 5 quarts; then 200 more miles and 5 more quarts so on.. Took about 2 weeks with this method and it is the only method I would recommend.(depends on how much you drive of course)

Smooth Transmission
PMC –
Wife’s 2007 V6 Honda Accord with 140k had slipping “hunting” 2nd to 3rd shifting. ONE drain and refill about cured the majority of the symptoms. The second drain and refill has transformed the response of the transmission. There IS a filter on the BAYA/BCLA transmissions that is user replaceable if you are reasonably handy with tools (does NOT require transmission disassembly).
I thought the transmission was toast as is too often the case with this year/model Accord. I was AMAZED at the complete lack of bad symptoms after the second drain and refill cycle.

I use this fluid for my fully built auto transmission and torque converter in my 98 Mitsubishi Eclipse GSX. Great stuff. Best price and fastest shipping for 12 pack bundle online. Ordered from Trends Auto here on Amazon.
