2001 gmc sierra crew cab bagged front and back, with c notch. on hard acceleration the oil cooler line on the transmission side keeps blowing out causing my fluid to go every where. When driving normally it’s fine but hard acceleration no. The metal clip on the transmission but the line blows out each time. And everytime I pull over, wait 15 minutes connect the line back and new fluid, and trans good if I drive nice and slow.
So I was driving then saw smoke pulled over then all the fluid was just poring out, it was on the left side of the transmission, don’t think it was the first time old owner had new field in the bottle, a funnel, and the fluid that came out looked new not even 1000miles. What could it be. Truck was 4.8l but switched to 5.3l. Truck is bagged but didn’t low to hit anything
