I just got the tranny back from the shop, drove it home and checked the fluid. Looked a little low. It was showing on the stick but the 2 little holes towards the top were dry, the usualy have fluid in them. Shop charged me for 12 quarts. New converter went in as well. So how many quarts, with a stock pan, does a new converter and new 4L65E hold?
Also, I have a couple of quarts of Mobil ATF D/M, Dexron-III Approved for H specification. This is what I used in the old 65E.
Question: Since I don't know what type of fluid the tranny shop put in and won't know until Monday, is it ok to add my fluid or would mixing be bad?

 

Nobody knows how many quarts in a fresh tranny?

 

I put 12 in my 60e when i did the shift kit install... maybe they really didnt put 12 in.

Mixing it SHOULDNT be bad... just dont mix synthetic and reg.

 

I remember putting 13 quarts the first swap I did but that was a little too much so 12 should be good, but this stick sure looks to be reading low. In park, engine hot and running, level surface. He charged me $2.61 a quart, what does synthetic cost?
P.S. If you put in 12 and didn't replace the TC, wouldn't the TC hide a quart or so even after draining the tranny? I wish I had a manual

 

Yes you cant get all the fluid out of the tc it will hide about a quart. 12 sounds right thats how much it took mine. I believe synthetic is like 5 bucks.
