ok i went to the parts store and looked at the haynes manual and it doesnt say anything about changing the fluid the t-5. tells you how to check the fluid level. but not how to change it! can anyone tell me how to do this! i need to this to my tranny. the reason why im asking is ive heard people say if you remove the wrong plug, that yeah the fluid will drain out, but you will lose reverse or something like that. please help.

 

Im almost positive filler is on the pass. side of the gearbox. There is one toward the top of the side and one on the bottom. They take a 3/8 extension to remove them and the lower one drains the top one is the fill.
also i think you use dexron automatic fluid for some reason and fill till it starts coming out of the hole then its full. I may be wrong
