pause between shifts after tuning

i never really thought twice about it, and the time that the pedal spends on or close to the floor is minimal anyways. After i installed the srl tune from matt on the truck, seems that when i mat the pedal it takes an extended time between shifts, but when it does it shifts quick and firm. not a slipping, and doesnt seem like a trans issue, just maybe a tcm issue? anyone else have this with the srl tune?

Re: pause between shifts after tuning

Mine does the same on my 7.3... when i asked matt he said something along the lines of the tune makes the truck defuel so it doesnt harm the trans. Ive had his tunes for just about 2 yrs and still on stock tranny. Nothing has been done to it except an oil change.

Re: pause between shifts after tuning

its the solenoids in the trans getting weak... dont know why matts tunes seem like they're the only tunes that make it apparent.

I get a nice flare on the 3-5 shift

Re: pause between shifts after tuning

I have not noticed this with my SRL tune. It shifts quick and firm, of course I came from a Banks 6 gun to Matt's tune so maybe I just don't notice.

Re: pause between shifts after tuning

oh, youd notice, it takes a while between shifts, but if i bring the pedal just a little bit off the floor it seems like it breaks the tires loose easily shifting gears. i was thinking maybe a hole in the tuning,

you need to replace you direct shift solenoid in the trans with the gogo diesel solenoid... its an OEM one modified on a solenoid tester that flows 4 times the fluid of the stocker...

over time all of the solenoids wear out so some trucks may be different than others.. only my 3-5 shift has a flare where is some may see a 1-2 or 2-3 flare (these are different solenoids)

Re: pause between shifts after tuning

Re: pause between shifts after tuning

matt expressed concern about a possible fuel pressure issue, going to look into it a little further, see if i can get it in the pids on the ids and monitor it there, im not going to install a fuel pressure gauge on an otherwise stock truck.
