    This fix WORKS! I bought the valve and oring from Sonnax. No more issues, but I reused the old valve body.

    I think I may have experienced this issue with my 99 Suburban this week on a road trip. We were in Yellowstone park and all of a sudden the upshifts were viscous hard. I was sweating it, thinking the worst, but hasn't done it since then.

    Van70style, how hard is the fix? The only thing I've done to a tranny is replace the fluid and filter. It looks like there are a million parts- a bit intimidating!

    I saw the Sonnax website and they recommend some tools to bore out the valve. Did you do that too?
    Current Rides: |99 Chevy Suburban- the family truckster |93 Lincoln Town Car- 250K miles & still churning -now a fan of the Panther platform |95 BMW 325is coupe- Wheeee!

    I've used this inexpensive part# A74741Q (www.fitzall.com) before and it works great.
    It can even be fixed without removing the valve body from the vehicle.
