Major improvement with MT82 fluid change

[Varekai]

2cool, I got all the stuff to do this, will be doing it in the morning, including the pump. Did you remove the whole center piece like in the mtw shifter install vid or just the area around the shifter to fill back up?

If you are using a pump you should be able to do the entire job from beneath the car without having to pull the center console or shifter. The fill hole is on the side of the trans about halfway up.

Oh so it's not on the top like the guide that was posted?

That is the gravity method. With a pump you don't need to go in from the top.

Did the change out earlier. Poured the leftovers into a old oil jug, came up as 2.5 quarts. The rear was a bit lower than the front tho since I had the front on race ramps and the rear jacked up as high as I could, so maybe it didn't all come out. Either way don't feel much of a difference, still some notchiness.

Before I invested in a pump I used to gravity fill manual trannies by using a long hose that I stuck in the fill hole and stood next to the car with the bottle of oil at roof level.

Which fluid did you use?

The royal purple synchromesh that the OP used

All done from underneath. Took all 3 quarts, still did not flow out of the fill hole.

After doing a ton of research on line, I'm going to go with the Motorcraft Dual Clutch Tranny Fluid (QDC) with the X-18 Additive as called for by the Ford Service Bulletin and current Ford/Motorcraft Transmission Fluid Chart. Apparently once Ford went with QDC and X-18 additive the cold shift problems with the German/Chinese Getrag MT82 seemed to clear up substantially. I also talked with a Getrag representative who said unequivocally that QDC was a lighter viscosity lubricant and the X-18 additive is essential as it maintains a presence on the gears especially if the vehicle has been cold soaked or not run for a prolonged period...the X-18 aids in cold shifts and then reverts back to a more viscous property under heat. As far as using other after market lubricants...he was pretty non committal and offered that if you use QDC and X-18 Ford will totally warranty your Gearbox but using other than QDC and X18, you're in essence rolling the dice. he suggested that before you purchase any fluid other than the manufacturer recommended fluid, you check with the specific manufacturer or Ford itself (I believe that the Ford Transmission Fluid chart lists NO other fluids other than QDC and X-18) :clap2:

I did my first oil change at my dealer yeaterday, me and demon coyote,another mustang6g member, have the same mt82 problems and both cars from the same dealer. The service rep told me about the additive however he said they wont flush and install it in their dealer so that i have to take it else where. I m kinda confused on whats going on. I wonder if the tranny breaks afterwards they dont want to take the responsibility or fix the hard shifting issue and thud noises. If we infact use the XL 18 or Royal purple and the tranny goes bad, can they tell what fluid we had in the car? Do they apply a chemical analysis on the fluid, color, smell or something gives it away? I m driving this car in freaking -10 degree temps sometimes so need a solution asap.

When it's really cold , I shift 1st the 3rd until it's warmed up.

I did the fluid change yesterday and used Amsoil. I had already installed the MGW shifter last weekend. I would say the fluid change helped with the notchiness quite a bit and it's worth doing. Temps here have been in the low 20s, so it may even be a more noticeable improvement once things warm up.

I did the fluid change to Royal Purple Synchromax yesterday, and installed the Whiteline trans mount insert at the same time.

The feel is greatly improved. I don't know which made the most improvement, the insert or the fluid. Shifts are much smoother. It's still a bit notchy but with less resistance going into gear, engagement is much smoother. The thud actually goes away once the fluid warms up. The shifter moves less during acceleration with the insert.

But HOLY NVH BATMAN! The feedback into the cabin from the trans is magnified by about 5 times now. The OEM transmission mount is very floppy. And now I know why; so all the noises from the transmission aren't sent directly into the cabin. I can clearly hear when the MT82 sings me the song of it's people. With the mount hardened up, I can hear every bit of gear lash, every synchro engagement, every bit of wind-up and backlash in the clutch hub, and engine vibrations are really transmitted into the trans tunnel. If you're thinking about this bushing, be forewarned, you are trading about a 50% improvement in shifter engagement feel for a 50% increase in driveline noise transmission into the cabin. I personally don't mind, especially with my future intentions for the car (next week is the SCCA Solo season opener), but the average-joe driver may not be pleased.

Looking at the engine mounts and trans mount design, the engine mounts must be doing 90% of the work. The trans mount is only there to offer some vertical restraint, relieving the engine mounts of overturning moment due to the CG of the drivetrain vs. engine mount location. It offers no lateral stiffness, no fwd-aft stiffness, and no additional torsional stiffness. I guess it shouldn't surprise me, given the fact that the IRS does not, in theory, impart any loads on the transmission due to displacement of the axle, like in a solid-axle design (in reality, it will, but in greatly reduced magnitude). Also, seeing that the trans mount is a carry-over from the S197 Gen 2 and seeing the piss-poor shifter design of that car, I also now fully understand why the previous gen car had so many shifter problems that we don't have and I'm surprised that it passed any kind of engineering design review. The floppy rear trans mount with an IRS is doable, but not with a solid axle back there moving around.

On a closing note, I am considering switching to RP Max Gear 75W-90 at the end of Auto-X season, just as an experiment. While looking up torque specs, I found a few discussions regarding Max Gear vs. Synchromax, and one being better than the other for different temp ranges.

This is semi off-topic, but will this get rid of my car's jerkiness/jolts? Mine jolts before I come to a complete stop (2nd to 1st). To explain it better, if feels like if I were being somewhat rear ended (or bumped)? Or is this something completely unrelated? or a different issue?

Maybe it's a engine or trans mount issue?

Trying to find a solution to this. It's driving me insane and no dealers want to touch my transmission.

I apologize again if this is not supposed to be posted here. I'm just out of ideas, and a bit frustrated.

I'm guessing from your sig that you have an automatic? If so this stuff were talking about is for Manual transmission cars. You wouldn't be able to use any of this stuff. But if your having a problem like what your describing, you need to go to your dealer and have the car looked at asap, it definitely should not be doing that.

Yep. This thread about manuals.

However, is this happening in normal mode or sport mode? In normal, I barely feel it downshift when slowing. Only sometimes depending. On sport mode, you'll feel it and that's normal for that mode.
