It just screws on the top of the tranny fluid bottle and you pump it by hand to pull it threw a hose into the tranny. Fill her up till fluid starts coming out again, then put the plug back in and call it a day.

if u pull out the fill plug and stick your finger in there, it should be just about level with fill plug. hence the "fill till spill"
and your car will also have to be lifted evenly to get accurate readings.

you can use a pump to get the fluid into there. you can pick one up at your local autozone.

Just to chime in with my experience. 2002 Formula. 500miles- in went RL ATF and Diff fluid along with RL engine oil 5w-30. At 16K miles of freeway driving and I didn't even start getting on the throttle hard till almost 2K miles. I babied the car, doing only 55 on the freeway with varing speeds and oil changes every year, incl the tranny and Diff. Well, at the 16K mark, my tranny gave out. Under warranty, I got a new one. I have since put 1500K on the tranny and changed it out to AMSOIL ATF. What a difference. It shifts smooth and the SOTP fell was nice. So my vote goes for the AMSOIL in all of my cars in every component that takes oil. Even there grease is awsome. The coolant is 7 year green coolant. This is just my experience, I hope it helps.

Should be no problem. I would just use a good name brand DexIII (i.e.; Pennzoil/Havoline/Q.S./Valvoline, etc.).

Hmm, so being that my car is a 98, I should just stick with Dexron III, or is it worth it for me to upgrade to GM Synchromesh? My tranny has been fine, no problems, but I have never changed the fluid in it and now she has 52k miles on it.

Not to throw another monkey wrench into the works, but has anyone tried the Amsoil MTF (Synthetic Synchromesh Fluid) or ATD (Torque-Drive Synthetic ATF) ?? The MTF is a direct replacement for the GM synchromesh part #s, and the ATD is a Dex 3 replacement. Are we right back to square one since they are both synthetic and therefore considered useless/harmful to T56s? Any Amsoil dealers out there with any experience with these in our transmissions??

For those that say only DEX III, have you even ever tried anything else? I have had notchy transmissions before, and I switched to Synchromesh. The notchyness went away and things were nice and smooth.
For the person who called Tremec... When I bought my Tremec 3550 for my Mustang, they specifically told me to only run Synchromesh or it would void the warranty. I had already been running Synchromesh anyway, so I wasn't concerned. Unless there is some major things different between their aftermarket transmissions vs their OEM ones, I don't see why they'd change their minds.
Trust me everyone, if you have never tried Synchromesh, you are missing out on a very smooth shift. If you don't like it, switch back. I can almost promise you will wonder why it took you so long to switch in the first place.

I was on a road trip coming home from Palm Springs (visiting my buddy there) and my tranny got stuck in 5th gear. I noticed some really hard shifting between 6th and 5th for about 1K miles, but I figured "no big deal" and took the car to So. Cal. Well, on the way back, the shifter got locked into 5th gear while downshifting for traffic.
For the life of me, I couldn't get it out of 5th. I had it taken to a dealership nearby who was going to work on it. Come to find out, there is a part inside the tranny that seized up. Now I don't remember what seized up, but I could still drive the car in 5th gear only, I just couldn't use any other gear. The shifter was really lose in the 5th gear, I could move the shifter around with a little resistance. The dealership could not fix the problem because of a special gear puller that they didn't have, so they just put in a brand new tranny for me. Since than, I have put 1K miles on the stock tranny fluid and have since changed the fluid to AMSOIL ATF and it made a huge difference. It shifts smoother, feels nice. I had a new tranny put in about 2 years ago with 17K on the car, I now have 19K on the car and no problems yet.
