OK, please don't flame, I did search before posting.

I recently changed my tranny fluid to transynd. I asked service dept at local Alli dealer when I picked up fluid and filter how much will drain out w/o removing pan. "10.6 qts" he said without hesitation.

Removed drain plug and external filter and let 'er rip. I had no way to accurately measure fluid removed, but I added 8qt to start with b/c what did drain out didn't look like 10 qts. Drove the truck about 10 miles and checked fluid. It looked like I'm about 1/4" or so above the HOT/full mark.

Truck runs/shifts better than I remember, but I'm still concerned.

Question is: How much should drain from a stock alli with stock pan by just removing the drain plug and external filter? And, if I'm overfilled 1/2 or a full quart or so, can't I just pop the drain plug back off and do a measured drain-off? :confused:

I haven't towed yet, and it's fairly cold here, so the tranny temp hasn't gotten above 130-140 since I changed the fluid. (Driven about 100-150 miles total.)

Just draining the pan and filter should be about 7 qts, you could pull the plug for a split second to let a little out.

Thanks! Should I be concerned about being over 1 qt?

i would just drain a little so the level is within the "hot" fill mark. you may get some fluid coming out of the overflow vent on top of the tranny if you don't

Yes, you can drain a little out just take the plug out part way out. I had to do it to mine when I over filled it. If not it will puke fluid all over the place when you get it hot enough. Mine never did it until summer, and then I had a hell of a mess to clean up. I beleive it also introduces alot of air to the system which is not good.
