Was looking over the owners manual for my 2006 Maxx LT, (I have the 3500 v6) and it showed that the 3500 V6 automatic transaxle has no dipstick, where the one used on the 3900 does have a dipstick.. So the question here, is why they went with the no dipstick for the 3500 V6 transaxles. What I'd like to know, is how can fluid level be checked? Manual says not necessary, unless leaks are found.(fortunately I have no leaks) But I like to periodically check the fluid level.
