What is the fix on this , My 93 for the last 7 years the check ball in the trans has not been working. When I crank it up in the morning I put it in nuetral for about 4 seconds to let the fluid go thru the system. I am going to put it up for sale and would like to fix it before I sale it. Is there a easy fix. thanks ...

 

hi
a transgo shift kit ,
comes with a special manuel valve to allow fluid flow in park .
ditch the check valve !
