I recently had all the oils and fluids changed on my car, except one didn't happen, and I am wondering if it should be. The SMG hydraulic fluid, is that something you guys who drive hard or occasionally take to the track, change on your SMG's? Also having some equipment like skid steers I've noticed they have huge radiators for their hydraulic systems, makes me think if anyone has done a kit or build with a cooler on the SMG's hydraulics side? I am fully aware of the cooler for the gear oil on the tranny tho. And I understand for street use its probably not needed!
