Dodge 62te Where is solenoid "H" p076a & p084a Sign In

I have a 2012 Dodge Grand Caravan with 62te transmission that is stuck with "limp mode" .

It was used so I don't know the full history but it has been working great for the 2 & half years I've had it. This problem is a recent development.
It has p076a code & p084a code which I have identified as problems with "solenoid H" & low/restricted fluid pressure. I was a bit low on fluid, but had no leaks that I could find & held its fluid level. After topping up the fluid it seemed to work for a while, but then went back to old tricks! So now I have done an filter change with new fluid. The old fluid looked okay, not sludgy, no debris or filings etc. But its still limping! And yes I cleared the error code.

I have tested the solenoid pack with a multimeter & it showed no anomalous Ohms readings. The wiring harness seems to check out too, although there are a few other connections I haven't checked yet.
I have looked at various schematics but none of them identify which solenoid/valve is "H". They all use different technical names for the solenoids! Not letters like "H".

I am sure this schematic name/error code name discrepancy is another one of Dodge's little "bleep you" moves to home mechanics (like ditching the trans dipstick) to try & make us go to the stealership where they will then try to sell us a whole new car.

If I have to change the solenoid I need to know which part to buy! If I need to inspect the valves for blockage I need to know which one is "H"! If I have to open up the case I want to only do it once!

This is very frustrating! It is like going to a 1st day at work & being introduced to everyone by name, "Joe", "Bob", "Tom", "Dave". Then the boss hands you a widget & says "take that to Twinkle-Toes". Well it must be a nickname, but no one will tell you whose!

Where the heck is solenoid "H"?? Is "H" in the pack or is it the "TCC" solenoid? Where on the valve body is valve "H"? Does anyone know?

Thanks for any help in advance!

P.S. I would take this to the local tran shop,(he does free diagnostics) but he is booked up for the next month!

I'll let Gary confirm this but it appears it's all one assembly and solenoids are not sold or replaced separately.

Yes, the solenoid pack is sold as a single unit. But there is also a separate solenoid, called the "TCC" solenoid in the schematics I've found, which is outside the pack.


I do not know if solenoid "H" is this "TCC" one or if it is one of the ones in the pack. Obviously if I need to replace the problem solenoid I must know which of the 2 parts to buy.

The TCC is the Torque Converter Control solenoid and only controls overdrive.

Hello,
Po76A is DC or Direct Clutch solenoid Circuit(electrical) The P084A has also to do with the direct clutch, this code means the PCM is testing the direct clutch pressure switch and it is not closing, problem could be solenoid pack. Gary
