Hummer H3For the Hummer driver who wants the rugged look and off road capabilities of the Hummer, but in a smaller size and with a more fuel economy friendly engine.
Hi guys,
2007 i5 here, I had the transmission rebuilt a little over a year ago coz of some issues and now it drives well, except that the P0741 code did not clear. Mechanic said solenoid is good but I really do want to change it for good measure. A couple of questions (please assume that I'm dumb with these things);
1) In the attached pictures, it says no. 5 is the TCC/PWM solenoid - is that the one I should change for the TCC On/Off solenoid? I previously thought they were two separate solenoids but I'm not too sure anymore. If possible, a part # would be of great help!
2) Could anyone lead me to like a solenoid kit set with the harness? Might as well change all once it's open.
Your mechanic said solenoid is good, yet code shows stuck. Replacing the solenoid will not be a guaranteed fix!
I understand, however unfortunately most mechanics here aren't very dependable when it comes to electrical issues in parts like these and I've only figured that out much later than I'd like. At least I'll be certain it isn't something as simple as the solenoid once I have it changed out.
Could you please tell me if no. 5 is the correct one to change out or am I missing something? And do you know of a solenoid kit w/ harness for the '07 i5? Thanks!

Make sure to clean the valve body! The TCC is on the right front of the transmission. After you drop the pan, identify the parts. Many yt videos on how to change. JUST MAKE SURE TO CLEAN! #SeaFoamWorks

THANK YOU SO MUCH! Seems like the TCC solenoid is hardwired to the harness.
I'll be ordering the OEM kit, this is great help thank you so much! I'll update once I get it done. Thanks for tips too!

Did you ask the seller to throw in a can of Seafoam Trans Tune? Btw, it happened on mine, lost 1-2, dropped the pan and replaced 1-2 & 2-3 and installed a new filter and fresh dexvi(flushed within 20k miles). Test drive gave me just 1, 1-2 shift. I immediately opened a can, and drove a few miles, manually shifting, until it came back automatically. Never a problem since! My fluid is the same color as new fluid, however I only avg around 1k miles a year now. Caused by varnish? I don't care, It's been shifting perfectly and smooth for over a year since, and I have 2 good working shift solenoids for backup. GL

I did not, problem is I'm in the Middle East so the shipment forwarding service I use does not allow shipping flammable materials so I can't have the seafoam trans tune :/
Follow up question tho; did you only have only 1-2 shift coz the computer was relearning from the new solenoids or was there something else going on? I'm worried now that if I change all solenoids and get into a situation like that
TCC solenoid and P0741
