Torque Converter Clutch solenoid needs to be replaced

[dkknaebel]

But I can't quite determine which one I need. I have a 1995 Chevy 2 door Tahoe, 4l60e, NP241 t-case. I keep getting two different ones in my search. One is a plunger type with two leads coming off of it, the other is a L shaped solenoid with a input for a harness. Can anyone help me out with this? The transmission keeps unlocking and locking the TC, it shifts just fine 1-3, then it won't stay in overdrive, it will go in and out and the rpms jump around when it does. Going to try the easiest fix first.

If anyone has questions regarding the 4l60e, Rostra Transmission has great online support. They recommended I replace the whole wiring harness and TCC. Rock Auto has it for dirt cheap, definitely going to start here and see if I can solve my TC and OD problem.
