1. A thermal bypass valve, comprising:
a plug having an inner cavity longitudinally extending between two oppositely oriented openings and a cap configured to prevent fluid flow between the thermal bypass valve and a valve bore in a transmission, the plug configured to insert into an opening of the valve bore;
a longitudinally extending plunger configured to be secured coaxially through the inner cavity of the plug and extending beyond the two oppositely oriented openings of the plug;
a blocker valve having and a fluid channel longitudinally extending between two oppositely oriented blocker valve openings;
a first spring configured to be secured between the plunger and the blocker valve; and
a second spring configured to be secured between the blocker valve and a surface of the valve bore,
wherein, when the thermal bypass valve is installed in a transmission, a position of the plunger relative to the plug is manually changeable to enable full transmission fluid flow to a fluid cooler, full transmission fluid bypass of the fluid cooler, and mixed transmission fluid flow to the fluid cooler and to a fluid warmer.
