SOURCE: Chevrolet Malibu 2001 Transmission Flush or not
75,000 miles isnt alot of miles,unless they were mostly city miles. If you aren't experiencing any transmission problems,i would drop the pan,change the filter and whatever fluid the pan holds,and hold off on flushing the entire sytem.The clutches and bands sometimes don't do well when shocked with ALL new fluid that contains a certain amount of detergent.The only real problems i have seen with the total flush is on Dodge trucks of the 90's up to even 2000 and some later models,the transmissions use a governor pressure sensor,and solenoid,and i have seen many of them set codes after the flush,and the components having to be replaced with new.Black fluid isn't a good indicator.Brown fluid,is better than black.And red fluid is the best.

I First, you must remove the black air deflctor that runs underneath the radiator across the car. Maybe about 8 bolts. Even then I couldn't find the drain plug at first. It is on the driver's side. Beneath the radiator there is a heavy metal Mounting bracket. Almost looks like a crossmember. About an inch in from the left (driver's) side bottom of the bracket there is a large round hole with a rubber grommet. In the center of this hole it the outlet of the drain. If you reach directly above it on the back side of the radiator, i.e. come around back on the bracket and looking forward, you will find the drain ****. It is black plastic and has 2 ****, not a full petcock handle. It is still hard to see, even after removing the air deflector. The air deflector is the one people knock off by running too far forward when parking. I hope this helps .Remember the 2 or 3 vents at top of radiator hoses when refilling the system.
The radiator does have a hard to see drain plug on the left drivers' side. There are 5 10MM screws holding the air deflector on. The block has removable plugs, one 14MM hex next to the oil filter and one in about the same location on the other side of the block toward the firewall under the exhaust manifold.

Transmissions these days need very little maintenance, our fluids are advanced formulas that hold up for an average of 100,000 miles, most vehicle manufactures recommend no maintenance for automatic transaxles these days.As for a transmission flush I don't recommend this because it's an expense that is not needed and possibly could loosen some contaminants setting them loose to possibly clog some of the very small passages in the transaxle requiring full transaxle service,which could include removal,dissassembly,etc of your trans.Now draining and replacing fluid is OK if that makes you feel a peace of mind but normally not needed,if you decide to do that,as far as quantity just note approx. how much fluid is drained and purchase similar amount in quarts and then refill (DO NOT OVERFILL)
start engine, let it warm up to operating temp,then check the transmission dipstick for the correct level,remember the vehicle needs to be on a level surface,hot idiling in park when you check the fluid level. Good luck !
