TRANNY!!!!!!!!!

[younggun55]

Running the 310 earlier today transmission started acting really funny and threw a wrench, it said something about shift solenoid D being stuck, but I cleared the code and everything was fine. Now truck won't shift into 5th. I am loading a different tune now to see if it will fix itself but highly doubt it. Is this a common solenoid to go bad? And if it is stuck would that prohibit the truck from shifting at all?

I am guessing you turned the truck off and then back on? We have had that code before, material got stuck in the solenoid. Replaced that solenoid and everything was fine. Might want to look into the tranny filter kit from suncoast.

You can bet that "material" is clutch material. Which means that you are hurting your tranny. You can continue to change/add filters and solenoids when they get clogged, but you cant get around the fact that you are wearing out your trannsmission.

A tranny "makes" metal as a normal function of it's operation. The quantity of this metal and fiber mix is what determines if it is normal wear or failure beginning. Aaron is correct, that adding a inline filter on the return side helps keep the solenoids clean and working properly. Even a stock truck or good tranny will have metal and other material on the magnet during regular service. This doesn't mean the tranny is going bad. If the inline filter continues to need replacing then yes the transmissions days are numbered.

I'm well aware that there is a certain amount on material on the factory magnet between normal servicing. We deal with this in our 900/1200/1500 hp 4R70W trannsmissions all the time. These trannsmission are built to handle the power and the fluid is inspected frequently to ensure no damage is occurring.

If it was normal wear the stock filter would pick up what is not caught by the magnet. If you have so much debis that you have to add an extra filter to keep the fluid clean it is not "normal opperation" and the wear should be considered excessive. I assume younggun55's truck is not a race only vahical like Aaron's race truck and sees some mileage to go along with its fun time with the go pedal through the floor.

Lets face it. All of us running these high power tunes are most likely going to need trannsmission upgrades sooner than later compared to the lower hp tunes, but you gotta pay to play right?

Have we determined if in fact it was material that caused the solenoid to go out. Mine did the same thing this morning running the 210 tune, will not shift into 5th got wrench and codes P0766 and P2703. Only a couple days after putting in the Suncoast direct solenoid.

Same thing happened to me, but I got a code about clutch packs too. Truck wouldn't shift for a while, drove 40 miles doing 40, then I turned it off again and it would shift fine. I haven't really pushed it yet to see if it will hold or not, cause I don't know what to do a tranny til Suncoast comes out with something more solid.

what does this do for you? I see a lot of you running this solenoid. Just wondering.... thanks

I have one because my stock one went bad. It increases pressure on the 3-4 shift.
