My transmission was not pumped after Baja. It got hot on me and boiled over (common A4LD issue). I've also been dealing with it slipping every morning when it's cold (another common A4LD issue). Threw in a new filter, a big Hayden trans cooler meant for a Class A RV towing 10,000, pounds, and installed in a drain plug so that I can keep the fluid fresh in the future. Trans is happy now, cold slippage issue is gone, shifts nice and solid. Also threw on a spare black grill, and put some little daytime runner leds in the valance. Got about a 200 mile dirt adventure planned for this weekend, good times!
