Maybe its a stupid question, i live in wisconsin, i have a 94 astro van with 275,xxx miles still running very strong. My question is im going to be taking it on a road trip probably abougt 3 to 4 hours away. I want to check the oils engine and transmission, do i turn on the engine and let it warm up for both engine and tranny or how do i check it properly thanks.

Check engine oil when cold

Check trans fluid when warm , drive about 10 miles or so at 25 -30 mph and that should be warm enough ,

Do not check after a 55mph highway drive as it can give false reading , let it sit for 15 minutes or so then check it after highway driven
