The torque converter Solenoid is located below the intake directly under the thermostat housing. It is the black connector not theo maroon it is the further back one. The hardest part is getting the 10 mm bolt off that holds the solenoid in. The way to test is to first drain the ATF and then pour it through a paint strainer the finer the better a small amount of flake is too be expected and fuzzy metal material like what comes off the ATF drain bolt. However if you see a fair about of metal bits your transmission is done probably.
If you didn't see a lot of contaminants then proceed to tet the solenoid.
1 leave the solenoid in place and use a multimeter to ohm it out 12-25 is normal range
2 if it ohms out ok the hook up leads to the positive and negative battery terminals and connect the positive side to he left pin (if looking at it from the front driver side corner o the car) and the negative to the right you should hear a solid click when you touch the negative i it sounds hollow or weak or no click at replace the solenoid (27 dollars)
Btw since your there you should test the solenoid nfront of it and also the solenoid pack ontop of the transmission. The 2 pack on op of the solenoid has tubes that can become clogged clean with carb cleaner and replace he main gasket. Also this would be a good time to change the exterior transmission filter. It is located just back from the battery towards the firewall the bottom bolt is hard to get off so if you hav a ratcheting wrench it will help.
You could also mod the system with a manga fine filter instead and not replace the factory one as when it becomes clogged it just goes into bypass anyway an an exterior manga fine filter is easier and better anyway.
I am going through all of this right now and am hoping that it is just the solenoid, but I know it may not be there are many fine DIY's on the modifications I hav mentioned. New redline fluid may let you get more time but if e transmission is gone it is going to go. If you do end up replacing the transmission make sure you change the 3rd & 4th pressure switches regularly like every 50k at the most. Reman Acura transmission are 2250 with a 3yr/36000 mik warranty doesn't hav to be put in by Acura. Also Atkins vege seems to have good pricing and a better warranty 3 yr unlimited mileage. Local shops from ATRA will do better price wise thn the dealership. But if you hav ha regularly maintained your ca with the dealership make sure you ask to see if acura of amercica will do a goodwill repair if of warranty sometimes they will cover 100% sometimes 50/50 be aware that th dealership will try and charge 3400 fo te transmission don't let them there is a 1200 core charge they should credit you back for bringing th cost to 2200 to 2250. Alo while they are in there make sure they change the motor and transmission mount they are dropping the subframe should be just he parts also if a t belt is due might as well have them do it hen since they are dropping it should only be slightly more labor and if the steering rack is leaking change it then too along with the compliance bushings in the lower control arm. Last bit of advice price your parts at oemacuraparts.com or acuraoemparts.com these are actual Acura parts you can reference against th quote your service advisor gave you and challenge their cost model as you could buy the parts direct from a Acura dealer for less. Anyway my rant has gone too long, luck too everyone experiencing transmission issues with their TL great car picky transmissions.

I just went through this with my NEW TO ME 06 acura, among many other issues, I went for a road trip and it threw the same code, p0741. torque converter lock up. I did indeed notice that she wasn't locking up. I checked trans fluid and it was BLACK, so my car has 165k km, I'll say it's never had a service done on the transmission. So I got a new oil filter, theres an external one ontop of the case, its a cartridge style. I removed that to find it was... basically plugged with very fine bits of metal, again from lack of maintenance, filter should of been replaced long ago. I then drained the oil and put in new atf with sea foam trans tune. I also just to cover the basis, replaced my Torque converter lock up solenoid, it was only ~$50. I went for a drive and not only does the transmission shift better but the torque converter is locking up. hopefully I don't have any more issues with that. my car's still throwing rich codes both banks, no idea wtf it is. ugh. at least 1 problem down.

Depends on how long ago you bought it, if it's been a few days/ a week or 2 they may be willing to help, otherwise they may just "discount" your labour lol. If your a half hands on guy, you could do it, Gotta remove air box. But I did have a car hoist to put it on for the trans draining. But otherwise it was straight forward. Also if you do it your self capture the oil you take out and measure it, so you know how much to put back in, can't go wrong
