I'm questioning the oil level indicator on my trans dipstick. I'm not sure if it's the correct dipstick for a 1971 426 Hemi trans as I'm told they are different from others. So, if I drop the trans pan for a filter swap only, how much trans fluid should I be expected to put in?

I can answer the question. If you buy 6 quarts, you'll need 8. If you buy 10 quarts you'll need 5 As mentioned there are too many variables to give an accurate answer.

Standard capacity for a 727 with a stock pan is about 5 quarts. If you are gonna change the filter and fluid go ahead and drain the convertor if it has a drain plug. It is behind the flat shield, behind the oil pan, on the transmission housing face. You may have to rotate the engine to find the small drain plug. Not all torque convertors have them today but the factory did back in 1970.
Draining the torque convertor will add between 2 and 4 quarts to the 5 above depending on the size.
I can't find a good picture but the dipstick should extend into the transmission about 3/4 of inch or so. Here is a small block tube for reference. The level for a 727 will be the same for all engine types.
The difference in a Hemi Dipstick should be the shape of the tube not the depth of the fluid.
John Kunkel is the resident Auto Transmission expert and may have better advice/pics. Good picture. I guess the question is if all dipsticks protrude past the tube the same distance. I understand '71 Hemi auto transmissions are a bunch of new and old hemi parts pulled together.

GTX - The problem is it's a '71 Hemi trans. I understand hemi auto's holds 6 quarts but not because the pan is deeper which adds to the confusion. My pan looks exactly like the pan on my 440, no difference in depth so where does the other quart go? The extra hemi cooler doesn't look like it can carry another quart but maybe 1/2 quart? And from other posts, the dipstick is a different on a 70-71 hemi vs 67-69. If I could empty the entire system, then add 6 quarts, then mark the stick wherever the level is would solve the problem but getting everything out sounds like a lot of work.

I hope that was not my post, I misread the trans discussion and posted about the Oil pan stick. According to the parts book, the hemi trans dipstick was the same part number 66-71. The tube changed in 69.

I did a little more checking since I was home near my parts books and all the Hemi's from 67 to 71 used the same part number dipstick. I believe 68 Jim posted his dipstick was in the neighborhood of 14" so the hemi stick is shorter than other engines. Excellent Info GTX. Thanks. I must say though, the stick section cut and rivets look factory.

Funny that on my dipstick, there is an "M" stamped after the part number. M for Modified?? My '71 Hemi carbs are actually 1970 carbs modified for the 1971 Hemi with an "M" stamped in front of the part number. I understand that this is factory correct for a '71 Hemi.

At least one of my dipsticks had an M stamped on it. Maybe it's a stamp from whomever made it or? None of mine had Rivets though. It is common on some manufacturers factory dipsticks to have rivets but I can't recall one way or the other any from Mopar back in the 70's so I can't say for sure.

That is what I said earlier. The stick is the same, the tube chanced as they went from bolt on to press on tube. Isn't M mopar performance part numbers. DS - Here is the dipstick with the part number and the "M". The M might not even be associated with the part number.
