Any and all help is grately appreciated. Thanks
could be a few things offhand that i can think of...
1st, it could be that the checkball capsule in the case, could be in the 2-3 accumulator in the servo, 3-4 clutch apply piston has cut lip seal, or 3-4 clutches have too much clearance. or the 1-2, accumulator piston and pin are worn.
is this a new build or a high mileage trans?
the transgo jr kit addresses a 2-3 flare/cut loose shift as theyre known to have this problem.
