Having a issue in a buddies turbo truck with the 2-3 shift just flaring into the rev limiter. Have tried everything from lowering the shift point, shift times, torque management, and force motor current
Its a built 60e with a ptc converter, he may chime in but behind a 4.8 on about 11 psi. Ive been told it could be the 3-4 clutches wearing but im at a loss on what to change in the tune now.
Help!!!

 

What are the shift times set to?

 

What yr truck

 

Well, a useful start in the tune would be to do an 80E segment swap, then do supporting mods.

I think you're asking too much of any 60E. I'd imagine a 4.8 on 11# would be doing around 575HP.

 

Its a 00 2 bar sd os. the shift times are at .200 right now have tried .000 to stock shift times with the same results.
Pretty sure we may have just pushed the little 60e too far but the fluid still looks fine, you can literally lift off the gas for a second and get back on it and it shifts.
Not sure what it makes for power but it just ran a 11.9@114 having to lift 2-3 shift with a lackluster 1.8 60'

 

Using funny math, I get an estimated 504RWHP for an 11.9 quarter mile. Which is pushing the limits of any 60E.

 

Did you figure out your shift flare? I am going through that right now also. I have a built 4l60e by rpm transmissions and mine make the least power but still has the issue. I was starting to think wheel speed not matching shift speed? But it does the exact same thing, same gear. A buddies did it and he drove to a different tuner a little ways away. And it got fixed. So I'm guessing it's in the tune also. He just didn't ask. what was . Thanks

 

It ended up being the trans, we tried setting the shift early and all. Trans guy said its probably the 3/4 clutches wearing. Hes going 4l80e as we speak
