Had my oil changed today and also the tranny oil w/ GM Synchromesh because 3rd was difficult. Tonight drove it downtown in city driving, did not miss one shift into 3rd.

BTW, had service at Honda dealership and it was much cheaper.

The Honda dealership put in the GM fluid for you?

I was actually talking to my local Acura dealer about this, they suggest the fluid so much they stock it.

IIRC it was ~13 per quart and about 30 min. labor. It totaled something around $100 with tax.

Once or twice a week I'll get just a little notchiness going into 3rd and am planning on having this done while it's barely an issue.

My Acura dealership wouldn't put the GM stuff in it, but they did eat the cost to put the 2007+ lube in (which is supposed to have more friction modifiers), it was better for a month, but then got worse. I did the Synchromesh change myself and have been absolutely tickled! Been more than year now and still not a single jump back out of third. It gets a little notchy in the cold, but it's never spit it back out like it used to..

i know this is a 3gtl thread but i use to work for Honda
and the 06,07,08 civic si 6 sp mt had a recall for it popping out of 3rd gear randomly and they had to replace 3rd gear to fix the issue. u know how Honda is for using the same parts in different models so who knows if its the same 3rd gear or not.makes u wonder

^most honda's have the 3rd gear grind or popout.

I'd rather use the fluid than for a tech to tear into my ride and possibly messing something else up.


GM syncromesh has cured my 3rd gear pop out.

how you guys replace trans fluid? flush and put GM stuff in it? or you guys do 3 interval?

Thought GM juice was discontinued?????????

You can still get it, just call a local GM dealer ask if they stock that part number (make sure it's "Friction Modified"). Sometimes it comes in an AC Delco bottle from Canada though (same stuff).

All the Honda 6-speeds are known to do this. This is why GMSMFM is so damn popular. It even helps on old worn out transmissions.

Just drain drain & fill. Flush is for automatic transmissions. In case you were unaware, we're talking about the 6-speed manual.

I had the exact same results on mine. At exactly 1000 miles, the 3rd gear started acting up again. Then it got worse. The second time I took it in, they experienced the problem 1st hand during the test drive. Then they replace the 3rd gear synchro set under warranty. I didn't mind since Acura hands out loaners. They certainly did a good job and I've never once had it pop out of gear. 3rd & 4th are still a little stiff for my taste, but that is all. It's been a few years now and I'm thinking the fluid is getting old. I'll definitely switch to GMSMFM when I change it out.

like 94eg! said; this is only for 6MT!

TL_Trooper

Acura wanted to replace my synchro's too. After letting Toyota touch my Scion for a similar synchro issue (minus popping out of gear, just grinding) it was NEVER the same. Everything was harder to go into including Reverse gear.

94eg!

Same thing happened to my wifes 03 Honda Pilot AWD. GM Synchromesh FM fixed that too...

Whoa! I'm glad I saw this thread I didn't know GM syncromesh is also a good option for tranny fluid for TL. I've use it in my other car and it was good.

Hey. I saw a lot of posts regarding the third gear issue on 3rd generation TLs. I havea 2005 TL and there is always this grinding feeling whenever I shift into the third and even into fourth. There was a TSB issued in April 2008 on the same.
I called up the dealer and they said that its going to be 159 as diagnostic fee and the rest would depend on the costs. I know it’s been seven years for this car and there is no warranty but I just purchased this car couple of weeks back. I can use the GM Synchro FM fluid but that won’t fix the true problem. I am new to U.S. and would really appreciate some feedbacks on how I can best resolve the issue with the dealers.
a. Can I maybe convince them to help me out with some goodwill on the total cost. Is that even a possibility.
b. Should I go to a local trusted mechanic and get the 3rd gear synchronizer or 3-4 shift sleeve replaced.
c. Should I just continue on with it using the GM Synchro FM fluid and hope that the transmission doesn’t give up on me anytime soon. (if so the threads on the same are atleast a year old. Hence, any new suggestions on where I can get the fluid from. If not, I will just use the link from older posts.
Any suggestions from someone who faced similar problem out of warranty would be great.

Sometimes I wonder at that point, should you just swap the tranny rather than rebuild/replace parts.

of course you gamble with a used tranny.

UNC_Tl

Well thanks for the post Bruce Banner. I assume that including labor it should cost me more than $2000. Well that kinds of makes my decision - its GM fluid and then using the transmission until nuts, bolts and whatever other stuff is there falls apart. There is no way I can afford to spend 2k in this vehicle. Lets see, I am hoping like hell it lasts that much. But it still leaves me wondering that a Tata Nano, the cheapest car in the world (less than what the transmission is worth in an Acura), has a longer lasting transmission. So much for the brand name.

Thought I'd clue in the guys looking for the old part number. GM synchromesh friction modified fluid
old part number is 12377916
New part number is 88900399
Just bought the fluid for my 2nd change with because it's time and the parts guy enlightened me about the number change.

Just as a point of reference, the new bottle is labeled as ACDelco Synchromesh Transmission Fluid-Friction Modified, and has both of the following part numbers:

• 10-4014
• 88900399

DMZ

The new Honda fluid is just as good. Paul used it last change and its works as well as the GM/AC Delco stuff.

Thanks for this post. Third gear was popping out all the time on my 05 TL. I changed the fluid, using the GM Synchromesh type and the problem seems to be solved. I got a pretty slick filler tube at Walmart which screws onto the bottle, and has an on/off valve. Made adding the fluid to the case super-easy. No mess.

Count me as another convert. Changed the gearbox fluid a month ago; third gear issues resolved. Car has 118,000 miles.

I been hearing a lot about this 3rd gear pop out, I am guessing my car had the issue resolved from the dealership early on since it was dealer maintained. Recently car feels weird when shifting into 2nd gear, but only does it when the fluid is cold. (usually goes away after like 10 miles of driving or so) It did not do this in the summer. I was wondering if anyone else had this problem. I am going to change to GM fluid soon. Was just curious on if someone had a similar issue? Also is there any longevity concern using GM fluid in my TL?
P.S. Have a Stock 07 TL Type S 6MT.
