well my check engine light came on and i took the car to autozone and it came up with this P0740- TCC Circuit Malfunction......anyone ever experience this code???....i know that its the Torque Converter Clutch Circuit Malfunction but what exactly does this mean?......is there anyway to fix this problem or does this mean i need a new tranny???

if i need another tranny i will be real pissed because this will be the 4TH time

fsttyms1

thats what my last failure(which i isnt the same type of failure or associated with the 3rd gear) was which prompted a 6 speed conversion

Da_iLLeZt_TL973

thank you for the fast response...........that was the last thing i wanted to hear i think im done with this car

nyctl

your tranny is going chief!
if under warranty take it to the Ac dealer
if not, you gotz to shell out the funds for a new tranny.

i just had that same thing last month and my car is in the shop ever since.

fsttyms1

My recommendation is to bring it in and get a 2nd opinion to see what is exactly wrong

CL Platano

damn man..what tranny are they putting in that car you just got it fixed ..

sittinlow

damm steve.. I hope its not the tranny.. if it is, time to start on that new project.hehe

Da_iLLeZt_TL973

dam guys yea im taking it to the dealer friday morning to see what happens......

yea plat i just got the tranny done

adrian- yea man im ready to start the new project but im gonna miss my TL

fsttyms1

Mine happened right after i had mine redone (well about 3 months later) the tq converter failed and caused issues for the trans

Da_iLLeZt_TL973

yea i had mine done a little more than half a year ago and they shop that did it only had a 12k/1 year warranty on the car and i already put 12k on the tranny i believe i would have to check the paper work but im almost 95% sure im over the 12k mark

fsttyms1

that was my issue as well, i was over the mileage. Id call them up and talk to them to see if they will work something out with you

Got_3.2?

yo steve. sorry bout the news. yea id call the place and tell them that within 6 months ur tranny blew which shouldnt happen for $3000 that u paid for it. dont even mention that u are over the mileage.

Da_iLLeZt_TL973

kris- i will call the shop tomorrow and see wat they say but i feel like raising hell instead of speaking lol


mike- yea man this shit sucks i agree wit u 100% all that money was dished out for the tranny and not even a year later its acting up again.....anyway it might be time for me to leave the TL family i got no luck with this car

fsttyms1

let us know how it goes. Hopefully they will work with you

Got_3.2?

iTrader: (2)

once all this shit is done ur car will be staright. every1 goes threw there shit with cars mine with the noise in my brakes that lasted like a yr n a half lol. u have mad miles so of course things will start to break. they will most likely work with u on the tranny so ur golden.

Da_iLLeZt_TL973

yea man i agree with you hopefully after this nothing else will go wrong lol u kno how it is when u fix one thing then something else goes bad.......if it aint one thing its the other lol

Rouse1965

well my case was like this ,. Hope it helps someone.
2006 t/l . Bought brand new by me. 88,000 mile. a/t
transmission was randomly slipping.

Then one day it was having trouble shifting. it seem to get into 2nd or 3 rd gear. got worse as it warmed up.
Had it towed to a trusted shop that only works on Acura/Honda.
P0740 code came up when the tech test drove my car.But not until then
I have maintained the car well.

Need new trans and two motor mounts.... errr
rebuilt trans from Acura for $3125.00 in Sacramento , CA
given a 3 yr / unlimited mile warranty.

A hit to the C/C but car is paid off.

TLZINE99

that code = Kiss of death.

3.2TLc

So hey Rouse1965, an '06 TL bought new and "well serviced".......just being curious, what was your tranny's PM work performed on the car while ya owned it ?

Did ya have regular tranny drain & fills using Honda fluid or replace the inline ATf filter ???

What was the main part that failed......did the shop tell ya ?

vginotes

I have been getting that code p0740 as well, but I've read elsewhere that if I replace the lock up solenoid or clean the lock up solenoid and linear assembly I shld be fine. has anyone ever clean the linear solenoid?


I see a couple of videos already on cleaning the lock up shift solenoid.

Yikes

You can try, but many have taken that route here with no results. In all honesty you're wasting your time. That code means the damage is already done. Cleaning the screens or replacing the solenoid only gives clutch material and debris an opportunity to clog something else up.

Skirmich

Hello!, Your Trans is Toasted!!

3.2TLc

Yeah, too little ....too late.
Ya could try checking the ATF fluid's level and condition for shit and giggles.
If the fluid is dark and smells burnt, it may be time for an "AV6" donor replacement.

d4atls

Shop that just did mine installed an atf cooler and gave me lifetime warranty

3.2TLc

^^^ Did the shop that did yours.....replace or rebuild the tranny ?
Lifetime warranty, wow.....how much extra did that cost ya at the time ?

d4atls

Rebuild, added a new case and bearings for the shafts too.... along with the cooler and the lifetime warranty comes with. He quoted $1200 but called and went up to $1800 when he discovered the main case and bearings were gone. Was good enough to call and let me come by and see for myself too. He ususally never goes up on a quote but had no choice this time. He's kinda known for doing these transmissions in this part of bama.
