well i have 2010 ford flex EB with a SCT Livewire TS tuner what does the Line Pressure kPa refer to on the tuner i was thinking it was Fuel Pressure mine has dropped from around 2000 to 400 what do i need to check.

Line pressure is trans

Ok well that's probably why its not shifting right.  What should it be running?  Right now is runs in Park 395 kpa 56 psi drive 800 kpa/100 psi or so and when it shifts 1100-1800 kph/160-260 psi. Have any ideal what it could be any help would be appreciated.

Do you have any codes currently? Any symptoms when you noticed the large drop in line pressure? Have you tuned the car recently (as I believe trans pressure can be adjusted in tune)?

no codes  fluids full it started feeling like it wes bogging down at light throttle and shakes give it 1/2 or more throttle and runs good and the pressure goes to like 250psi

Have any data logs?

Well i have tried i have one but not sure what to do with it would like to talk to someone about it.  Would like to know what is a normal reading for the line pressure and i have started watching one called Torque converter Clutch Current (A) witch it says 0 till it shifts in to 3ed gear and it says 380 at 1387 rpm  and something called TCC Solenoid runs 13.77 PSI.

Could someone post there readings so i would have something to compare with Please 

Who is your tuner?

They should be able to help with log analysis and/or post it up so knowledgeable members can help.

Well i bought my SCT Livewire from Unleashed Tuning and i got the 87 and 91 performance tunes here is the only datalog i have
