My 400e shifts at 3500-4000 from a start. Then fwy speed past 65-70 mph when cable was at it setting.
Backed off cable almost bottom out so it would shift at fwy speeds. Still goes up to 3500-4000rpm from the start.
When I adjusted cable counter clockwise tightenend it would not go into higher gear until I passed 70 mph at 4000rpm. It is a normal progression of speed. Never adjusted past its rested position on the cam.
Thanks

I would try driving with the cable disconnected. Should shift at or below 1800 RPM under light throttle

No, all is normal

Checked vacuum lines all good. Re-adjusted cable and still shifting at 3500-4000. Also adjusted the modulator at trans. Fluid level good and filter, changed around 13K ago.
Help!!!

Well it has been a few months and all is well.Shifting normal around 2500-2700 rpm. Did a real good flush and filter change.I bought this used and had change the fluid and filter 13k ago. Since the recent flush it has been great.

Something was probably gummed up or plugged in the valve body.

I change my trans fluid with synthetic (and a new filter) every spring. It shifts and performs awesome. Fluid changes make the difference!
