Today, after about an hour or so of driving on the highway, the tcs and cel lights came on, then the car went as if on neutral and a few seconds later the cel light started blinking. I pulled over and opened the hood and this weird smell came out of it. I pulled the tranny dipstick and it smelled burnt, but the color seemed ok (a bit reddish, not really black). After that, I started the car, put it in all the gears, including reverse, but it wouldn't move. I pulled the codes from my scanner, which were: P1399 (Random/Multiple Cylinder Misfire Detected) and P0740 (Torque Converter Clutch Solenoid Circuit). I had a tow truck take the car to my mechanic's shop, after I told the story to him he said: Tranny's likely gone. What do you think?

I'm probably looking at a tranny rebuild. The question is, since there is no "official" Acura dealership where I live, but there is an official Honda dealership, is our transmission shared with any other Honda product so I can buy the parts needed for the rebuild?

Thanks in advance

 

That's not your tranny. Your tranny failure would be the D4 (since you have a 1999 TL like me) flashing.

By your symptoms above, it seems like your cylinders are miss firing and your either not getting any spark or fuel to the cylinders. And the torque converter lock up could be because your tranny was shifting and was being interrupted because of the misfires.

 

Honestly, do not go with a rebuilt tranny from Acura as some people are still having failures witht the rebuilt ones. Though, there have been fewer failures.. I would go with a 3G TL tranny.. someone over on the CL side had successfully put in a 07-08 TL tranny into his CL. It bolts directly in with no fitment issues but you will need to do a few things..

Here's the thread:

Actually his symptoms are a trans failure and 99% of the time when you get that TQ code trans is done. You dont need the flashing D4/5 to mean its toast. You can some times clean the solenoids and drain fill the fluid but that doesnt always work.

 

depending on trans model there are 2 solenoids in block on top side of trans attached with 3 10mm bolts.the transmission cooling lines also mount here. remove the bolts and the solenoids being careful not to break the rubber molded seal that fits the solenoid block itself. underneath you will find 2 screens if these screens are full of a brownish material it is converter clutch material.cleaning the screens and reassembling may prolong the life of the trans somewhat but it is a sure sign that the torque converter clutch <lock up> is beginning to degrade and fall apart. unfortunately a filter change requires removal and transmission dis assemblybut if the code persists a trans overhaul and new converter are pretty much the only answer to your problem.

 

Well you beat me to it dude! lol I did some research and was looking around on the code and came up with the above solution but like that solution says more than likely he needs a new transmission.

seems like he or the previous owner was not taking care of the proper tranny fluid changes.

 

, you got the hang of things now, easier to just get a new gasket though, it is only a couple of dollars from the dealer, but sometimes you can get away with using the old gasket though

 

any part number for those solenoids?

$235 for somtin that might not work....it all comes to me now..a member almost went thru wit it..but called it quits n jus got a new tranny

 

Thanks all for your input...I think I'm just going to have it rebuilt.

 

And maybe sell the car...

 

^ take your solenoids out, clean them drain the fluid and see if it helps. 99s are FAR less prone to issues than the 00+

 

p740 is the code I got when my tranny took a dump the 3rd and 4th time i got THAT code!

 

Such a shame that they can't even rebuild the trannies right! Could be the coils.

Do as fstyms1 says- he has actually rebuilt a few of these trans and the 99 has far less issues than later years
It may be a simple problem

 

The solenoids you are refering to are those on top of the tranny just in front of the fill hole?

 

Is this the same tranny as the 98-02 Accord?

 

not the same- not drop in or everyone would be doing it-

the regular honda trans seem more reliable than Acura...or there are more hondas so it seems like fewer problems

 

also might help that they only have an 3 liter motor compared to our 3.2, so less torque;
let alone being a couple of hundard pounds lighter then our acura's


also he is talking about a 99, so only a 4-speed, and not the shitty 5-speed

 

Well, not according to this...check this out:

They say almost the same thing about our transmissions...
http://autos.msn.com/research/vip/re...Acura&model=TL

That's why I thought they might be the same...

 

Oh well...

 

i would say they are very similiar to your 99 4-speed tranny, but not so much our shitty 5-speeds

 

I agree...

 

should i do this too??...ive had the code for about 6-8 months.. car still runs perfect..no slippage ....when i reset the code ..comes on when 5 gear kicks in on highway alond with srs light

(s2tj)

 

you can try. The mere fact you have gone this long with that code is beyond me. The 2 times i had that code i had about half a day

 

and for JterrorC saying he has already tried resetting the light, and it coming right back on after going into 5th gear, kinda diminishes only hope that his tranny might still be saveable, but only way to actually tell, is to do as recommended
