I have an odd thing happening. When my FJ62 is driven in hot weather, 80+, there is a clicking noise under power from the tranny tunnel. The engine temp and oil pressures are the same no matter the outside temp; only the outside temp makes it click. The hotter it is outside the louder the click... When I let off the gas its stops, get on the gas its right there again. The sound does not change frequency or pitch relative to the RPMS.
Any ideas?
