    aod shifting

    installed a rebuilt 89 aod behind my 302 in 65 coupe my question is it seams to be shifting fine 1-2-3 but overdrive shift in to early and shifts out to late sometimes won't shift out of od till about 30 mph. I have the line pressure set in neutral with the lokar tool installed at 38psi so I don't know if my line pressure is to low or high. any thoughts?
    thanks

    Re: aod shifting

    The AOD, in stock form, or rebuilt to stock, tends to have undesirable or lack-luster shifting characteristics. Probably the only way you'll get a better shifting response from it is to install a shift kit in the valve body.

    If this was an AODE (2nd generation AOD) or, the much better 4R70W (3rd generation AOD), you wouldn't need to buy a shift kit for it to vastly improve its shifting response. A few simple modifications to specific holes in the 4R70W valve body separator plate and you can program the shift points and line pressures through a stand-alone shift controller.
