Castrol Transmax High Mileage ATF
I see that Amazon has this for $4.50/quart ( ) . I need to do a pan drop/filter change (car has 17,000 miles on it and 700R4 has never been serviced, as far as I know). Would this be a good choice? Or just use Penzoil Dexron 3?

If your transmission oil is in good shape, (looks good, smell ok) leave it alone. Transmission oil can go a 100,000 miles easily, if it stays in good shape. If the oil is burnt, then do a complete change here. DO NOT use one of those machines that flush the transmission. They are known to cause create unnecessary problems. If you want to do this yourself, let me know and I will tell how to do it, a 98% - 99% oil change here.

Since the oil is fine, just add what you need. Age has nothing to do with anything, the filter will be fine If you have not driven it then, just make sure the TV cable is tight at WOT, and drive it easy for three to four miles to make sure there is no air in anything. Then recheck the oil level and go from there. Changing oil when not needed is not going to improve anything here. If you still want to do a oil change, let me know and I will tell you how to do it.

You, sir, are an honest person. Maybe one of the very few left. Thank you!
