Shifting

I installed Matt's SRL tune...and I gotta say...my tranny shifts like sh*t !!! I shifts hard, but sometimes feels like it doesnt wanna go into the next gear when it should. Also...if you lay into it, sometimes it acts like it wont go into a high gear (stuck in whatever gear its in until you let off the throttle). Its done this a few time when I jump on it trying to pass people when I was going maybe 40 mph from the stop light. It almost acts like I'm building too much line pressure or something. If I let off the pedal, it will shift. Runs like a molested gorilla from 50 to 100 mph tho. I'm just scratching my head. I'll try and call Matt tomorrow.

I did not mess with any of the adjustable tranny points in the SCT. The only thing I changed was the tire size rotation thing.

did you let the trans re-learn? If not I highly suggest you do, Matts tunes should shift real smooth under light throttle conditions. When WOT the 5r110 LOVES firm shifts so its supposed to do that. Every tuner uses a fair amount of line pressure under heavy throttle because the trans needs it. Your trans will thank you later.

Dont mess with any of te shift points all that stuff should be left to the tuner

His Srl should shift great. Trans learning is important. Give it some time. If it still isn't right contact Matt.

How long do you figure (roughly) it will take to re-learn ? I just changed the fluid...so that should be good. It just feels like sometimes the tranny wont shift when you put some decent throttle to it. Almost acts (feels) like if you had a manual tranny, and you pushed the clutch halfway in while accelerating hard....then let the clutch back out when you let off the throttle a little. Does that description make sense ?


I didnt adjust the speedo (with the SCT) for tire size (285/70/17)...could that make any difference ? (like maybe the shifting and speedometer readings somehow affect each other in the tranny program )

I know what your talking about hanging in a gear until you let out. The first time I went wot with it it held 4200 rpm unroll I let out then it shifted. After it learned that's wasn't a problem

Go on YouTube and type in Srl powerstroke and watch some vids of the tune. It will give you an idea of how it runs.

Here's a couple of mine.

"I know what your talking about hanging in a gear until you let out. The first time I went wot with it it held 4200 rpm unroll I let out then it shifted."

Ok now...."hanging in a gear until you let out" is a perfect description sir.

Secondly....you said it held till 4200....I have my rev limiter set to 3650...could that be part of it ? Maybe I'm on the limiter before I have enough line pressure to shift it ?????

You need to me sure to set the Rev Per Mile correctly, then drive the truck normal and give it time to relearn. Sometimes it takes less than 20 miles, sometimes less than 50 miles. Really no set mileage when relearn is complete.
