Re: [Chrysler300] kickdown problem on '57 Tqf (related to runaway 2-3 upshift ?)

["elmer tuuri" <eltuuri@xxxx>]

Light throttle 2-3 shift should be at 23-28 mph--never over 30. You have 
lengthened the rod
too much.Make sure it's not hanging up---binding or too weak return spring. 
Actually I think
some valve is sticking in valve-body.--or internal problem.You say it is a 
recent rebuild ---
bring it back
