I don't mean to defend my actions about a fix that too is so simple you can not goof up.
Having spent a small portion of my years with The Hydramatic and Allison Transmission Divisions of General Motors Engineering Staff, I always look for an alternate fix that can be performed in the field at the least cost and down time of the vehicle.
I know when a simple fix far exceeds the chance of adding further repairs is not a viable alternate.
The meer chance of the pin retainer falling off and having to remove the valve body un neccesarily is no option in my opinion.
The labor and material cost saving is apparent.
My unconvenional repair is doing quite well, there are no further leaks.
I am not encouraging any one to do as I, just relating that should there be a need there is a method.
