It's not slipping or anything. It just stays in the same gear till about 3k rpm.
It feels like I'm in ss mode but it's not. No jerking or slipping.

 

I'm not sure I understand the issue. Was it shifting before then when it was "normal"? The shifting depends on how u drive. If you're getting on it it will go closer to redline before it shifts. If u take your foot off the accelerator it will cause it to upshift then. Maybe a few more details and we can be of more help.

 

clean the pressure/shift selenoids per our diy or replace them
how old is the fluid?,,running the new `dw-1` honda atf?

motor mounts front/rear are good?--vac leak there will mess with shifting

 

Normal driving without going over 2500rpm. It shifts fine from first to 2nd and from 2 and on, it stays in gear longer than normal.

 

The fluid has no more than 10k miles and it's the new Dw 1.
I have the new redesign casing, where is this solenoid?
