Torque Converter / Lockup Clutch

Torque Converter / Lockup Clutch
Ok, so my 03 D2 torque converter isn't engaging. I have checked and replaced the fluid in the transmission case and a new filter. Is there a way to check the lockup clutch solenoid? Or is there a way to replace this part? What do you guys suggest to further troubleshoot this before I open up the transmission fluid case again.
Is there a fuse I am missing?

I don't have a code of any sort, just that it isn't working. I can tell because of the shifting that doesn't happen. I have owned it for about 1 week and just now getting around to this issue.

I had a problem with mine where the torque converter would lock up too early. Like, around 30mph. It would unlock if you stepped on the brake, but as soon as you let go, it would lock right back up again. The same would happen if you floored it. It would downshift and take off, but it would lock back up when you went back to a steady speed.
In my case, it was a valve mechanically stuck in the valve body. Which could be the problem with yours too. It could be stuck in the opposite direction.

There's some TS info in attached thread link. What's your RPM at easy going 50 MPH?

I have found that I need to narrow down and ohm port 32 on my transmission ecu, but I don't know where the EAT ECU is located. any idea?

finally found it on the rave manual, still getting use to that particular manual.
I tested my lock-up clutch valve and it was tested in the normal range, 39ohms. Im not looking into all the requirements for the torque converter to engage to ensure those electronics are working properly. Any helpful insights would be appreciated.

Your RPMs at 50MPH are higher than my 1800 after lockup occurs in 4th. Is yours stock?
Surprise you don't have any codes, did you also check for pending codes? What type of scanner are you using?
Recently somebody was surprised my ScanGaugeII would even show the trans codes many of which were pending prior to clearing when my x,y,z switch was acting up. Several new to D2 members in last 6 months have thought they had a trans issue because not used to the lower gearing compared to other vehicles they'd been driving. Hence the stupid questions to a newbie.

Glad you found the box and getting used to the manual.

Ill have to use a better scan gauge to pull any codes, however my check engine doesn't come on. Would the codes still show up and not have a check engine code?
Also, assuming all those codes are not showing up, I was considering doing a full flush and change of the trans filter. I attempted this earlier, however all my parts stores had a slightly different filter setup and I didn't realize this until I had it all apart, so I had to put everything back together with new and old oil. Either way, the converter was not engaging before that.
While the sump cover is off, should I try and make sure the solenoid valves are not jammed mechanically? since I know they are functioning electronically.
thanks again

Sounds to me your D2 is operating normal.
