transmission fluid mt6

[UnleashedBeast]

Oh fuck me running backwards!! I ordered the friggin Synchromesh Amsoil stuff instead of the MTG. Went to do the swap yesterday, first day I've felt good in about a month, and checked everything one more time before getting started and realized my mistake.

That sucks.

It's OK to use it. I prefer MTG because it's the formulation recommended by Amsoil. Many have used cheap Pennzoil Synchromesh with positive results. You may have greater gear roll over noise using it, but it works.

I took mine to the dealer for the tsb, and it was a night and day change in how it feels! So if you have warrenty go this route first , its free and helped mine. Mtg didnt help mine at all!

TSB fluid shifts better in cold weather because it's extremely light. You praise it now, but will hate it in the summer time. Your tranny will be noisy and would have shifted/sounded better during the summer with MTG. I honestly can't believe you wasted a true synthetic base stock lubricant like MTG for the TSB fluid.

He lives in a "warm" state. Don't think he'll have as many cold shift problems as the rest of us and the thinner fluids may have no benefit to him. As you stated he might have roll over noise all the time in his climate.

Yea I dont doubt that mtg is better stuff, it just didnt work for me . The 29 dollar a qt shit from ford is what made it feel right, and it didnt cost a penny. When this summer comes and its terrible on that end of the spectrum ill swap back agian , its damn easy job now that I got the pump and was able to capture the fluid. so good luck to you guys doing the swap ,just know thsre are better options out there from what came in the car from the factory!!!

My car actually grinds going into 5th gear when its cold. I didn't hear anyone mention grinding, just notchyness. Is this a different problem or same problem as everyone else? I just got the car back from the dealer yesterday because they replaced the clutch. Half the friction material came off on the pp side. They gave me a new disc, pp, flywheel and throwout bearing. I just called my dealer and he is going to research the tsb regarding the fluid and call me back.

I would take the car repaired as is....and put my own fluid in it. The TSB fluid sucks!

 

[Falkinman]

You're right but I want them to check it to make sure ita not something damaged from the clutch going bad.

Mine does the same thing. I'll be ordering MTG soon and filling it up, will report back.

I've also had issues putting it in first gear when stopped since new. First time it happened I only had the car a day or two and I was at a light in neutral. Put it in first and let the clutch out and Bang, it popped out of gear. I figured it was me not being used to the car but it happened again a couple of days later. Then I began to notice that sometimes when I put it in first the shifter would stop before it was all the way in gear. It would take significant pressure to "force it" the rest of the way to engage the gear fully.

My car was built on a wednesday so i dont have any problems. Yet anyway...

Mine does that as well. How odd that we would have the same problems on a transmission that was determined by Ford and the NHTSA to NOT be defective...

A lot of people with these symptoms fixed them by swapping the fluid to a quality full synthetic fluid. It does not mean the transmission is defective.

Grimace is "correct", For some unknown reason, Ford used a fluid that is not very user friendly. I researched for months as to exactly what could be "Gear Blocking" my shifts. There are many different theories, and I'm not one to throw money at a problem HOPING it fixes the issue. I like to know what I am fixing is what the issue is. That being said, I'm smart, but I don't have a degree in Mechanical Engineering(which is really what I needed), while researching I found mixed reviews on aftermarket shifters and brackets, mixed reviews on the TSB fluid swaps, mixed reviews on motor/trans mounts. Some people claimed it help, some claimed no difference, some say it made it worse. So I'll explain how I came to my current situation.
)Shifters/Brackets Due to the flexing of the trans in relation to the body, a firmer mount to the body is actually going to Mis-Align the entire assembly under high tq loads, also a shorter throw is going to increase shift effort, not the direction I wanted to go.
)Fluids, didn't think that they were a very important part of the puzzle.
)Engine/Trans mounts, in theory this should help keep things aligned, but I realized that wasn't what the problem was when I was driving, At first when I would get blocked, I would try again or try a different gear. Instead of doing that I would hold the shifter in the position where it was blocked and wait for everything to settle down, and then bam, it would go in.....Didn't have to move it left or right, it wasn't gates that were to close, or my shift being off to the left or right, the damn gate was just blocked....


Which made me start thinking, what makes the shifter slide into the gear? The Synchro's, so I started researching synchro's until my brain hurt. What makes Synchro's work, Friction......HUH, friction makes synchro's work, what the hell were they thinking. I need a quality lubricant to keep heat and wear down, but I need friction for the Synchros to work, that's got to be my problem.

So after looking at all the fluids out there, there are quality fluids available, I choose BG Synchro Shift II and all I can say is AMAZING, and that's after just 3 miles of driving. Does this resolve the Cold shift effort and grinds, don't know yet, will this resolve my whining bearings, likely not. But it does make it so I can shift the car into the gear of my choice, at the time of my choice. F U GEARBLOCKS

Welcome Aaron! Get some miles on your new fluid and report back, so far everyone I know who has tried BG SS II fluid has had nothing but good things to say. I have a collective 12,000 miles over two different transmissions using that fluid and recommend it to everyone.

 

[Falkinman]

Yes I would like to hear how it shifts in cold weather.

I am on my second winter with the BG fluid and I am loving it.

 

[Falkinman]

Grimace did you have trouble shifting in the cold before you switched to the BG?

 

[adspru]

I did, 25*F this morning, only 35 miles with the new fluid in, and while I could still feel the synchro's slowing spinning up, it's was half the battle as before, and the actual feel of the shifter, before it was like like moving a spoon though ice cream before warmed up, now it feels like it's already warmed up. Can't wait to send off a sample of the factory fill with 20k miles to see what comes back. My car shifted and drove perfectly for 10k miles, and then steadily went downhill from there, first came gear blocks, then came notchiness, then came 2nd gear cold grinds, then it started a faint whining in all gears but 5th. I could handle the cold issues(somewhat normal for all MT's, but extremely exaggerated in the MT82) and slight whining(not an immediately terminal issue, annoying all the less), but the "gear blocks" are what I considered to be the main defect, and biggest overall issue. I highly recommend anyone with a MT82 change the Factory Fill out ASAP with one of the well known compatible aftermarket fluids, don't wait for issues to arise like I did.
FYI, I tried really hard to get gear blocked in the past 65 miles of driving and was "Unable to Duplicate", I feel like a Ford Service Tech or an employee of the NHTSA saying that.....

I originally swapped fluids to try to get rid of a terrible whine(loud enough to drown out the exhaust and radio), but it failed in that regard. However after I got a new trans to fix the whine, I noticed the fluid the new trans came with made for extremely inconsistent shifting into 5th and 1st when coming to a stop. I swapped in BG Syncro Shift II once again after about a week, and those issues were completely eliminated. It was in the upper 30's when I swapped the fluid. I've now put about 1,000 miles on the new trans and new fluid, it's been in the teens early in the morning and other than the very first 1-2 shift of the morning the trans is completely smooth.

 

[JAJ]

...other than the very first 1-2 shift of the morning the trans is completely smooth.

That's consistent with my experience too. BG SS II produces excellent shifting in all gears once you get that first 1-2 shift of the day over with.

Where are u guys buying the BG SS II from?
