Where do I put transmission fluid at???

I know ya'll are probably thinking wtf?? But yes im a noob, I have a 94 3.8 mustang and I think im low on transmission fluid because its making a loud wining sound, but where do i check the fluid at, I know the automatic has a dip stick near the firewall behind the engine, but I have a 5 speed manual. Cant seem to find it anywhere! Just got the car need help asap! New to the mustang world! Can someone maybe send a pic or something? Would be a lot easier! Thanks loads!!

Yes I do! We noticed it when we pulled the axel to check the bearings, all was fine. I replaced a seal while I already had it out. I think I may be just low on fluid, but was hoping I could just add some! Again its a 5 speed manual 3.8L 1994 mustang. Thanks!! Cant drive it till I figure this out!!

Hey! No we pulled the axle out from the drivers side rear thinking it was a bad bearing, but the axle had no wear and the bearing was fine, so I just replaced the seal out at the end of the axle right in front of the bearing since we already had it out. Hadnt been changed ever, so I figured it was about time. Im thinking the noise im hearing comming from the transmission is because its low on fluid, so the gears arnt being lubricated so its gonna make a wining noise to me, thinking thats it...hoping! Because I dont wanna spend 7-800 on a used tranny! Also I know that Im hearing some noise from the drivshaft and I already know that they had a recall on my vehicle and that was fixed in the past, but because of the 4 15's and the wall in the back its adding more weight to the car and my driveshaft is now hitting the Emerg. brake bracket in 2 diff. places. So I guess im going to have to take the wall and the 15's out! The car is lowered also which doesnt help, and its almost impossible to get my on most lifts, thats why its gonna be hard for me to add fluid to the tranny, with having to jack it up to get to it. But I guess thats what you get with a show car gone daily driver! But yes, the main noise im talking about is deff. comming from the tranny and Im just going to try and find where to put the fluid in at, hoping that fixes the problem because like I said when we jacked the rear up to mess with the axle, we noticed a leak comming from the tranny, and it was deff tranny fluid!

Thanks a lot bro! One question is it necessary to take out the fill plug when adding the fluid through the top like you said. Just watched a video on exactly what you were telling me, see my problem is getting the car off the ground or onto a lift for that matter, car is really low. Thats why im asking. Thanks!!
