Bottom right on passenger side towards the back of it it, uses a 3/8 drive extension and remeber to put RTV back on the threds as well.
O and remember to torque no more than 20 lb. ft for fill and drain plug.
Items Required:
-- Four quarts of Dextron III Automatic Transmission Fluid.
-- Fluid pump (make sure the threads are big enough for the bottle) or a suction gun would also work well
-- Oil drain pan
-- Set of Rhino ramps or equivalent
-- 7/8" wrench
-- 3/8" ratchet
-- Roll of teflon tape or RTV
-- Creeper to roll under car

im a little confused about it,
should not be manual tranny oil?
another question, can be use 80w90 diferential oil for gears and standart trannys in my t56?
because today i check the level for oil in my t56 so i only have 2 liters for diferential 80w90 and i put it in the t56, 2liters¡¡¡¡¡¡
thats so much?
please i need some opinions

Car isn't huge on HP, so....
Filled at the shifter myself as well.
If I recall, tranny calls for 3.9 quarts and filling at the shifter allows for that little extra fluid in there.

I run Redline here, per recommendations from a former T56 sponsor on here...but the car is race only, so, best thing for the street? idk
do NOT run Royal Purple! Yeah rumors that it eats the epoxy on the syncros...well it happened to me in my GTO, and Tremec confirmed.

Curious what about Purple Royal

I rebuilt my T56 about a year ago, a few new gears, 3-4 steel shift fork, bronze pads, billet keys, new synchros, new slave, master all that stuff. That was about 12,000 miles ago and now it is starting to shift like ****, grinding on hard 1-2 shifts and it justs sounds bad. I tried bleeding it the other weekend and it is taking longer to go in gear, not good at all. I am currently running pennzoil synchromesh, I think I am going to change back to plan ole dex III. Its not hard to rebuild these as I did it myself but damn I hope I dont have to again.

I wonder if the fluid just breaks down and wears out around 12,000-15,000 miles. It seems no matter what fluid someone replaces it with it seems to get better. Could just be that you need fresh fluid quite often if you are racing or banging gears all the time All I know is my transmission sounds like **** now and I am going to get rid of the synchromesh this weekend.

i change my fluid every 4th oil change(2500-3kmi.) on my car so i guess that's why i never have an issue. i change the rear end gear oil once a year. the car sees less than 10k miles a year.
