No. MT fluid completely different from AT fluid.

 

Just placed an order for 3 quarts from http://www.gmpartscheap.com/. Order was accepted, and received this confirmation email message:

However, an hour later I received another email with the following text.

"THIS PART COMES 6 TO A BOX YOU ORDER WILL BE ON HOLD INTILL YOU OK THE CHANGES"

Not cool.

 

I replaced my tranny fluid yesterday with the GM syncomesh. I'm not really feeling any difference? Would it be maybe because I have a short shifter that already makes the shifts feel smooth? Does it take some time to actually feel its effects?

 

Just wanted to bump this thread.

I'm at 34K in mileage and I've FINALLY decided to change my tranny fluid. I should be doing it next Wednesday. I'm buying it from the Chevy dealership that DMZ recommended.

Thanks DMZ.

 

By the way, I'm not sure what you mean by that the short shifter makes the shifts feel smooth.

I have the short shifter and a countersunk Voodoo shift knob. If anything the shifts are much shorter, but also it takes much more effort. It is notchier than the original.

Since I have not yet changed the fluid on my car, I can't comment regarding it. Once it is done, I will report back on my findings...

 

please do, I also have the Comptech SS and a countersunk Vodoo knob, so I'm interested to know how its going to change.

 

Question - How often will this brand of fluid need to be topped off or replaced?

 

Yiz welcome, but you really let yawz go to 34K ????

After only 7600 miles, my old fluid looked like un-stirred metallic paint in the catch pan.
It's 9000 miles later, and it still shifts like the day after I changed it.

 

I am at 40,000 and have not changed it and have no problem with shifting. I guess I am being lazy or cheap, I dont know which one. I just do not think it is worth it since it is going in off of lease in 8 months. Worth it or not?

 

At this point, I couldn't tell ya. I didn't think I had much of a problem shifting either untill I did the change. But then again, have you ever driven a 6MT with the GM fluid running through the transmission's veins?

 

I think GM considers this fluid as a lifetime fill in all of their gearboxes..

For Manuals, I usually do one fluid change at the first oil change to remove wear metals from break-in (gearboxes break-in quite "dirty"), then I wouldn't change it again for 100K or so unless shift quality becomes a problem.

 

did this last week (around 7k miles). Shifting feels great, 1st to 2nd is smoother. Shifter seems more "glidey-er." Not sure if it was because it my first MTF change though...

 

Just changed to synchromesh FM at 21K miles. Kicking myself for not doing this sooner. I had the intermitment 3rd gear problem (worse in cold weather) and on the first drive after putting in the new fluid I knew it was solved. Smooth like butter. No more guessing about going into 3rd.

One problem I had was getting the fill plug loose. I used the method where you don't take the airbox or battery out and it was a bit tough getting the right leverage with the extensions and universal. I ended up finding a position where I did not need to use the universal adapter and got a big ass pipe to slip over my ratchet to get more leverage. Took one hell of a lot of force but it finally popped. They must have had Bubba at the factory tighten this one.

 

Not really. With a plug and washer that has the surface area of that "big old fill plug" you don't need "Bubba". Grandma will get it tight enough to be a bear next time.
After I changed my MTF using Honda/Acura MTF and saw little improvement I then switched to GM FM a few months later. That plug was just as hard to remove as ever and I was the one that tightened it a few months prior. I've seen the same thing on other cars.

 

Like I said at the beginning of this thread ....

Just like those who've replaced their rear stabilizer bar with the Comptech.


Still have no idea what those of you who still haven't are waiting for.......

 

My dealer replaced my MTF with the new Honda MTF fluid about 4 months ago. It was a slight improvement but unless I realy keep the clutch engaged while shifting into 3rd gear I will get the grind. Does the GM FM reslove this or I am just letting off my clutch too soon when going to 3rd gear. No problem with grinding in any other gear.

 

Change to synchromesh FM and your 3rd gear problem will be solved. Period. If you read through all the posts you can find on here you'll see that is what is reported from everyone. Like I said above, the first drive after putting in the new fluid I knew my 3rd gear issue was solved. Before, even when it didn't grind it had that notchy feeling going into third and I had to push hard to make sure it was engaged. Smooth as silk now.

 

I printed this picture and I am going to get this Monday (today)! It's worth it for third gear thing alone! Mine doesn't grind, but I hate the notchy feeling.

Thanks "Thony Soprano"!! (DMZ)

 

Warmer weather?

 

I talked to the dealer today; they said the GM stuff would void the warranty. So, I'll probably have them put the new Honda stuff in at the next oil change. Hopefully that'll fix it well enough, at least until 50k miles.

 

If memory serves me right, I seem to recall there were posts where some Acura dealers did use the GM stuff once upon a time.

 

Yes, I was one of those cases. My dealer replaced the factory fill with GM-FM at my request, and there was never any mention of voiding the warranty. Clearly this can vary from dealer to dealer ... or possibly from one service consultant to the next, so you may want to shop around a bit.

Anyhow, this was in June 06 -- about 9,000 miles ago -- and as ALL users of GM-FM fluid have reported, the shift quality has been FLAWLESS ever since. Look through this forum -- we are a bunch of picky, compulsive people when it comes to our TLs! If there were ANY ill-effects reulting from the fluid switch, there would be dozens of posts about it, no?

 

thanks for your reply.

The one thing I worry about is, and I know I dont have the proper term, there are these paper/kelvar gaskets between gears in the transmission. Certain types of these gaskets dont play nicely with certain types of transmission fluid. This isnt something that would show up immediately, but one of those things that happens years down the line. I dont know if its an issue with the TL tranny, but my last car it was and there were people having to rebuild tranmissions because they ran the wrong type of oil. (Even though it was just another brand of MTF)

 

................................................


19,000 miles later and still shifting like butta.

 

Yep! Am very pleased with them overall.

 

You would have seen it in other applications already is this was a concern. People have been using this in TL's for 2+ years now but much longer in other honda apps.

Also, does anyone have an exploded view drawing of the TL 6MT? Something from the service manual? It would be interesting to see if we do have those paper gaskets or if they're composite.

EDIT: Found it...but the gearsets are sold as an assembly it doesn't break out the p/n's.

I am so tempted to do this, I can't hold it in!

 

Wow I wish I would have saw this thread last summer.

Should I go with the GM or Amsoil fluid? Any differences?
I'll probably print off that picture and head down to the GM dealer this weekend. Do most of them carry it in stock?

 

No, they don't.

Your best bet is to note the GM part # from the picture, 12377916 and call the GM dealer parts depts and ask if they have that part # in stock. GM dealer parts depts do everything by part# . A Chevrolet dealer is more likely to have it.

 

It can't be that critical. From the owner's manual:

Notice it says continued use can cause stiffer shifting, not harm to the tranny.

With regard to the Honda improved fluid; my daughter's '07 Accord V6 6MT has the same third gear problem (probably has the same transmission.) Her dealer switched her to the new, improved Honda MTF. She reports a "slight" improvement, but that "shifting to third still sucks".

 

I have used Royal Purple, Redline, and Amsoil. They are performed excellent in the last 5 cars I used them in. Between the three I just get what is on sale or readily available. I will promise you'll notice a difference too. Ultra smooth.

 

I had the GM Synchromesh FM filled in my TL today. I had to get it done through Pep boys as I did not have space to do it myself. I provided the guys with 3 quarts of the GM MTF and the guy said he used all of them.

I told him that the spec says it will take only around 2.3 quartz but he showed me a book that he referred to and it said 3 liters. But I have a feeling he overfilled the transmission but how do I check the fluid level? How bad is that to the car if it is overfilled?

 

He definitely over filled it if he dumped in 3qts. I've done this job 3 times until I finally changed to the GM FM and it always took just under 2 1/2 qts.

There is no dip stick so get that thought out of your head. There is a "level" bolt (10mm I think) a few inches right above the MTF drain plug. It is the "level hole" for the MTF fill. When you refill, you put the drain plug back in, take out the "level" bolt and fill the MT via the fill hole (top of MT) until fluid weeps out of the "level hole". When the weeping stops you put the 10mm bolt back in. Do this while the car is level (not up in the front only) and you WILL have only about 2.3 qts in there.

As far as damage I'm not sure. I think you will get foam, or cavitation, which ain't good. IMHO I would check it soon, very soon. Others will comment I'm sure.

 

I've been using Specialy Formulations MTL-P as opposed to the GM stuff, as reccomended by Road Rage. Shifting is noticeably better than stock, but I still have getting to second difficluty in the cold (I attribute this more to the short shifter than the fluid).

Anyone else try the SF stuff out to compare it against the GM stuff. Just wondering "how much better" the SF oil really is, as I never tried the GM oil.

 

Just for comparison I have both the Comptech SS and the GM fluid and have no problems with 2nd in the cold. Every gear is smooth.

 

In a follow up to the issue of overfilling, can somebody tell me where exactly I can get the MTF capacity for Acura TL 2006 officially so I can show it to the Pepboys. Better if somebody can scan the spec and post it. I would really appreciate it.

 

Had the fluid swapped for GM fluid at the local mechanic a day ago. Can't say I immediately noticed the difference, but then I only have 9k on a car, and never had a 3rd gear issue.

 

In your glove box....
Should be in something like the "Capacities" section in the owners manual.
