    po722 output speed sensor no signal
    Po734 4 gear incorrect ratio

    Check the wiring pigtail to the rear most speed sensor on the back of the 5r55e transmission
    Losing D and being able to engage 1 and 2 manually, having a sluggish reverse, these are usually signs that your 5r55e is on its way out.
    But check the simple things first

    Here is the OSS or output shaft speed sensor on the 5r55e:

    410Fortune Thanks for the reply. The crazy thing is the trans has full power in 1 and 2 gears no slippage at all. heck it'll burn the tries off lol

    bt93, I bought my ‘01 because the guy couldn’t get it in to D - it would pull down and die. Reverse worked fine. I replaced all the solenoids in the bottom of the transmission
    ($20 at my local u-pull-it) and it’s been running great ever since. Turns out there’s one of those that go bad, I don’t recall which one, and it was easier to buy all 6 than to figure out which one was it.
