post your latest transmission lubricant change.

2010 outback, factory fill out as part of 30-month service, replaced 4.75 quarts, drain and fill, with beck arnley atf hp. Went great, will probably do another drain and fill at next oil change.
 
1996 Honda Civic DX; 102,400 mi; 1 June 2012.
Drain 2.9 qt and refill with Redline D4.

1998 Honda Civic LX; 106,400 mi; 1 June 2012.
Drain 2.9 qt and refill with Redline D4.

Both cars now have a mix of mostly Redline D4 and some Honda ATF after two drain and refills. The 1996 (subjectively) shifts a little smoother.
 
2005 Cobalt manual transmission - Filled with Pennzoil Synchromesh. So far, feels the same as the Dexron III ATF that was in there previously.
 
2002 Toyota Rav4 2WD; 131,000 mi; 26 Oct 2012.
Did a drain (about 3.5 qt) and fill of original (?) ATF with Valvoline MaxLife Dex/Merc ATF. Will follow up with at least 2 more drain and fills over the next two months, and then once annually from here on out.
 
2004 Toyota Corolla LE; 140,000 mi; 27 Oct 2012.
Did a drain (about 3.3 qt) and fill with Valvoline MaxLife Dex/Merc ATF. Will follow up with at least 2 more drain and fills over the next two months, and then once annually from here on out.
 
2004 Mazda 6S wagon, 9.7 quarts total capacity including torque converter and integral fluid cooler, 85,000 miles. Three drain-and-fills (~3.5 qts each) on respectively October 1, October 15, and October 29, with about 200 driving miles in each of the two intervals between operations. Topped off with Red Line D4 the first two times, and with LubeGard red (10 oz.) and remainder Red Line D4 the third time.
 
2010 Hyundai Elantra ATF drain & fill using Hyundai SPIII ATF which drained close to 3.5 qrts. . The ATF drain plug was a 17mm for reference...

'98 Nissan Skyline R34 25GT (naturally aspirated) 4sp AT

Out: Unknown: prior to my ownership

In: Redline Hi-Temp ATF

Mileage on previous fill: 4000kms (fluids we supposedly changed during the car's compliance when first imported - I did a fluid and filer overhaul when i picked it up)

Impression: no noticable difference, operation was smooth and seamless through gears - thinking of moving to Amsoil on my next fill @ 30,000km/20,000mi OCI


'04 Subaru Forester SG9 XT (turbo) 5MT

Out: Unknown: prior to my ownership

In: NEO Platinum 75w-90HD

Mileage on previous fill: 30,000km / 20,000mi

Impression: noticeably smoother when gearbox was at operating temperature - will try Amsoil for my next fill
 
2004 Mazda 6, 5-speed MT
Redline MT-90

I've been using MT-90 for almost the entire life of the vehicle. About 140k on the clock now. This last fill got about 4yrs/50k miles on it. When I got the UOA results, the TAN came back acidic, but wear numbers were excellent.
