Trans Upgrade?

Is the Suncoast Direct Solenoid a worthy upgrade?
What is involved with install?

Is the MagHytec Trans pan a worthy addition also?

Thanks

I would say yes to both, if the tranny is in good shape put a converter in front of it all and now your really talking. The solenoid install is not much more involved than doing a regular tranny service/changing the internal filter, one clip and harness plug and the solenoid is out. Let me know if you need help, or have questions. We have all that stuff in stock. Sean

It increases line pressure for the 3 to 4 shift to reduce wear on the direct clutches

I noticed a change in shifts with mine. Firmer and more direct shifts is what I have noticed. I have a stock DPF delete file, and I'm not sure how much, if any, Matt messes with the tranny tuning, but I notice that te 3 and 4 shifts are firmer than my dads completely stock 6.4....

The Suncoast Direct Solenoid increases line/holding pressure when shifting into 4th gear (i.e. - 3rd Shift.) It doesn't actually affect the harshness of the transmission shifting if the TCM is able to go through a relearn. The easiest way to explain it would be this, it increases the actual holding pressure of the direct clutches under WOT to prevent slippage and wear. Most 5r110 failures are related to direct clutch slippage and failure.
