    What scanner would I need to have that done? Ford scanner or something a trans shop might have?

    If I tab brake pedal, it unlocks the TQ... always has since I have had truck.
    What tells trans to unlock?

    Thanks

    Mark, if you have a moment for another question...
    My 06 is still having the same issues but has added a new quirk. When cruising down road in 5 locked (per CTS), if need to accelerate or say climb an incline, it does not want to come out of locked in overdrive. It starts to bog and just blow dark black smoke out pipe and not accel. I have to bump brake pedal to get out of OD locked and go to not have it do this mosquito fogging.

    Could this be a symptom of one of the tranny issues that you mentioned?

    Thank you again for your time.
    Dave


    PS: I have tried this under two tunes, and stock programming and turbo etc seems to be fine per the cts. Truck had 8 new injectors installed a month ago.

    What would I be best to tell a shop to check?
    Does it have to be torn into to find those issues?
    If it needs rebuilt, what do you suggest they do for a bit more power?
    <studs,stageII turbo, atlas 40 on FICM, street tune>
    Thank you

    Dave,

    It's either a worn direct clutch, a slow shift solenoid D, or a leak in the direct clutch circuit. Checking line pressure isn't going to find any of these problems. It's also possible that the problem is the intermediate clutch releasing too soon, due to either wear or a leak. Either of these will cause a flare on that shift.

    Mark, good afternoon. I am wondering if you can share some knowledge with me? I have an 06 6.0 CC 4x4 with 228xxx on it.
    My trans is hitting a "lull" when shifting into 4th as shown on Edge CTS2... It seems to quit pulling for a second and sometimes rpm will raise then it "catches up".
    I understand this is actually 3-5 shift as this is when warm. I have had line pressure checked at two different shops and they keep telling me it is in specs.
    It has gotten worse in last few months and I really dont want to ruin the transmission. I have upped the line pressure by 5% via SCT X4 on 3-5 shift which didnt seem to help. Recently had trans hot flushed with new filters and fluid. Anything I can look for or request they change/test?
    I have not been to a Transmission only shop with it yet but understand not everyone/every shop knows these.
    Thank you much.
    Dave

    Did the 2000 E350 2WD Diesel vans have the earlier 4r100?

    Having an issue with a transmission re-builder.

    The build date on my original is MAY 2000 and has a worm gear driven VSS

    and the one the shop sent me has a different magnetic VSS and diferent output shaft size.

    Hoping for clarity from the expert,,
    Thank You,
    Harry

    I'm going to do this flow test you recommend, but before I start I would like to know, If my flow is not good what is the best way to flush my brand new coolers ?

    Thanks in advance
