    i have a 200R4 in my Skylark, this may not be an issue however I just wanted to run this by some experienced guys. When I take off and make a left it right turn, the transmission shifts hard enough to bark the tires. This is normal turns not getting into the gas pedal. I just want to make sure this will not harm the transmission in the long run. Going straight is no issue.

    Take it to the parking lot and do slow speed/idle 20 of each, lock to lock right turns, left turns and figure eight turns.

    That will help lubricate the clutches and help rule out differential and not cost anything.

    If that does not help, post back.

    Is the torque converter stock?

    Idle speed?

    Sudden onset, or has this been since it was set up?

    Fluid level (tranny) and condition/color/any metal (best seen in the sun or few wipes of the dipstick on white paper towel).

    And, are you certain no incorrect fluid has been added?

    Some years back I read an article where they road tested one of these with a pressure gauge connected. The 200-4R filter picks up fluid on the top rather than on the bottom like most transmissions. The results were that running 1 quart over the full mark worked best because of slosh. I've ran mine like this with no problems, and I've had mine in the car for about 12 years now.

    TexasT Texas, where are you from

    Definitely need to check your pressures. And I would recommend a 700r4 bottom feed filter instead of the 2004r top feeder.
    No fluid/sucking air is death to a trans. This condition will wreck a clutch set and band by not applying it fully and keeping it applied. Slip em a few times and it just gets worse.
    I'd also like to recommend a larger boost valve, rev boost valve and 700r4 spring to raise the internal pressures of the trans.
    And if you do go to the 700r4 filter you need to be aware of the vb switch and a way to keep the filter from grounding it and introducing a whole new set of probs.

    Due to the approaching storm to the Carolinas I will not get the car out on the road until after the storm passes.
