What does a modded direct solenoid acutally do?

[Jonnydime]

Like the title states what does it actually do and why are the only shifts that I have problems with connected to this solenoid?

 

[BOSS450]

The solenoid does manually what a tuner can do in tuning. it increases pressures.

So do I need it?

 

[BOSS450]

Technically no. A stock solenoid can do almost the same thing with tuning. I'm waiting on my bottom end to be finished so my 450 will go back together and I have a stage 5 going in it. Got ahold of tad and he stated he no longer had the tuning software.... But said that Matt has the correct files to write a tune for his stage 5. So I'll give it a shot or two then i was going to pull the whole valve body and run another company's. That's my plan.

Let me how it work's out since I am in the same boat with my stg 5. Forrest(drunk on diesel) sent me his trans file to try and it is awesome besides the fact that 1st to 2nd and 3rd to 5th are a little harsh. Matt's files are great as well but I like to try everything.

Just back down the desired slip tables a bit on the shifts that are hard.

Mine will be a while as pistons are still on back order. So a couple months still
