The fluid level should be checked when the engine tempurature gauge indicates a normal warmed up condition and the fluid in the transaxle is heated to its normal operating tempurature. Operation with an improper fluid level will greatly reduce the life of the transaxle and of the fluid.
Fluid Recommendation: Diamond ATF SP or equivalent
The wire transmission dipstick on this 1998 GSX can be really hard to read the first time. I did not check the fluid level before changing the fluid. So I had no reference. I first put 4 quarts in and started the car. Ran it through the gears and checked the level. The problem with this is that the dipstick gets residual fluid from the dipstick tube after running a bunch of fluid down it. Also, make SURE to use Neutral for checking the level. Park read 3 quarts over-full for me... So, I can't tell if the fluid I'm seeing is showing a level in the pan or just picked up from the tubing. Eventually I filled it enough to see a drip on the end of the dip stick. Cool! So I filled it a little more and checked it again. Getting closer. Finished off the quart and it checked perfect.
Moral: check for a drip on the end of the dipstick when refilling. Not just ATF residue on it.
Your two main options:
1. Auto --> 5-speed swap and a performance clutch.
2. Beef up the automatic and install a BIG transmission cooler.
