P0700 and P0741
Hey everyone, the other day, I was driving my wife's 07 LT 2.2 (129k miles) and the check engine light came on. I scanned it and got:
P0700- Transmission control system mil request and P0741- torque converter clutch circuit performance or stuck off code. I did notice a slight whining in the transmission in 3rd gear with light acceleration, and the transmission doesn't seem to be going into 4th gear. Does anybody know if this could be just a bad TCC solenoid, or am I going to need to overhaul this transmission?? Anybody have these symptoms and codes at all before? |
Would a bad torque converter clutch solenoid cause the transmission not to shift into 4th gear?
|
YES, that is what 4th gear is.
The description is " torque converter clutch circuit performance or stuck off code", so it could possibly be a electrical thing. |
It could also be chaffed wires or loose ground wires or TCM connection

I guess my plan of attack will be spend the $30 on the solenoid and change that first and see what happens.... worst case scenario, I'll rebuild it for $440, but I'd change out that solenoid either way, so all I'm wasting is time if I do the solenoid job and need to tear it down again |
$30 for the part, $400 labor. You have to drop the entire cradle. I think R&R cradle is about 10 hours.
Gears 1-3 are inside the gearbox 4th gear is when the torque converter locks and the engine (basically) drives the wheel directly, overdrive. |

TCC solenoid
So did the TCC solenoid fix the issue?

Welcome to the site, the OP hasn’t been back since 03/21/2016, so I doubt you will get an answer.
