Anyone down the Upgraded valve body?
Feedback please.

I've tested the Suncoast valve body + pump on my car for about 3 days and 100 miles.
I used FORScan to update the solenoid strategy number as well before testing.
It was part of a cat 3 kit but I installed just the clutches first and tested with the stock valve body + pump (where everything worked great) before switching to the Suncoast valve body.

Personal experience:
1. Very harsh engagement shifting into drive, rocks the whole car like it was hit (Worse when trans is up to temp).
2. Downshifts are mostly smooth but sometimes very harsh and feels like the trans is about to drop out of the car.
3. Upshifts are mostly smooth as well but sometimes has shift flares at part throttle.
4. There's an RPM drop that happens right before the 3 - 4 shift. Can be seen in the video at 00:05, 00:26, 00:44

Didn't bother doing any WOT tests and reverted back to my stock valve body where everything is working fine.
During my short test it performed ok but just seems clunky/rough around the edges especially for a daily driver.
My Suncoast valve body might have an issue but no way for me to know that without trying another. I'll contact Suncoast to either get a replacement or return it.

Would be good to hear feedback from someone else with the valve body + pump and how it works for regular driving but my personal feedback is to hold off till you get more feedback from real world users.

we need more imfo like this.

I'm fairly certain that Suncoast has said the valve body/pump will require special tuning above and beyond just the strategy change. Shortly after release, some of the tuners were complaining that suncoast was not providing any information about what needed to be done. Not sure if this has changed.

There's nothing on their site - https://suncoastdiesel.com/i-30500957?q=Valve+body - regarding special tuning for the valve body except this:
"For maximum results in power levels exceeding 800HP, it is highly recommended that the TCC apply offset be changed in the factory file calibration"
Which shouldn't affect any of the tests I did.

Spoke with my tuner as well (one of the major ones) and there's no unique tune for the valve body. Not ready to start tuning/logging for those little annoying niggles on a part that should be plug and play.
Might have received a defective one or it just doesn't work well with my car.

@beefcake did you require a special tune for your Suncoast valve body?

 

[mustangflanagan]

I thought it needed a tune also besides the solenoid strategy also but who knows could be wrong.

If it does that'll be great so I don't have to deal with replacing/returning it

Terry mentions it in the very first post of this thread.

I had gotten through to Suncoast tech support at one point. I only recall the TCC apply part and optionally trying shorting shift times, if desired. Sorry to hear of your experience Exploded. There's got to me some kind of response to now the car is shaken violently going into drive....

I wonder how this valvebody will do in colder weather for daily drivers with the thermal bypass removed

You will need a thermostat, I've got an external like others here works great.

 

[beefcake]

The TCC offset is really the only thing

 

[Bullit69]

The TCC offset is really the only thing

What does that consist of? Simply via tune?

 

[beefcake]

It’s just one parameter in the tune

 

[mustangflanagan]

Any updates on this? Debating this or a stock valvebody... Can anyone find price for a stock one?
