    That sounds very unusual. OD should function the same as D with the exception of locking out the 3-4 shift. Can you give a more detailed description about what is going on?

    Yea i have never seen a trans do this but.........all other gears function fine can drive threw all with exception of OD. Only time it acts up is in OD it acts like its in N but i checked linkage and all looks fine and if you try to push it up while driving just revs.

    Its a valve body problem, you need to get your valve body rebuilt. Its caused by a blown valve body gasket causing a loss of pressure to the hydraulic circuits so they don't engage. It could also be caused by a valve seal in the valve body somewhere.
