Please take the poll -- and then post what you use, what transmission you have, and why you use the grade you use.

Mobil 1 TES-295. Allison approved ATF. Fully Synthetic. Lowest price fully synthetic I know of. I use it in everything.
Where I work is a National Bulk dealer. $34.00 a gallon! Let me know if you want me to bring you some to Commerce.
I've looked inside garbage truck transmissions with 15,000 hours on them, and they don't even have the "normal" back stuff in the bottom of the pan! This stuff is really amazing!

While I'm with you on the durable and clean part -- I'm wondering about the required friction for racing.
A lot of guys use to swear by the Ford stuff -- and they said it had more friction for quicker harder clutch engaging for racing.

Guess in the 'old days' the firmer shifts were true. The Allison trannies shift and lock up torque converter clutches, with almost 2,000 foot pounds of torque applied (AT VERY LOW RPM, compared to racing). The TES-295 fluids can handle it!

Type F in my C-6, usually avalable at Auto Zone here in Chicago burbs. Motorcraft distributors also. Would be interresting to see what various race trans/converter shops recommend. JPT converters recommened type f.

I use the ATF 4 as well in our 727 lightweigt trans, tried the synthetic weird results, it turned a gray color after a couple of passes. I took it out and haven't tried any other brands. poppaj

I know the aluminum drums are lighter -- but we use the billet steel drums because they don't foul the transmission oil in just one event.

I use Type F in all of the race transmissions I build and recommend it. Have never had a failure due to the fluid so I stick with what I know has been successful. On street transmissions, usually Mercon except in O/D's then I use whatever the factory recommends. I have never really seen the benefit of the extra expense of synthetics.... except in the ones with a clutch type lockup converter, the synthetic does keep that clutch from chattering when it applies after it has quite a few miles on it. Have had a few with a chatter and changing to synthetic stopped it.
I have never tried it myself but I know quite a few "old school" Mopar guys that use Dexron/Mercon with a quart of 30W oil in their transmission. This was recommended by Chrysler in their performance books.
