A6 tranny getting too hot! Help please
I posted last week and thought that I had it all figured out but I dont.
2011 grand sport auto
ECS T trim (newly installed)
3500 stall Circle D (installed few months ago)
B&M Supercooler plate tranny cooler 70266 - 11"X8"X 1.5" thick - stacked plate design.
E 85 fuel system.
Fresh blower install so Im taking it fairly easy - im not ******* it at all.
It was running up to 220 in 40 degree weather driving normally - this was with no fan on the cooler and the cooler NOT in front of the radiator - the intercooler is not leaving enough room.
Today I installed an electric fan pushing thru the fan - there isnt room to put it on the other side to have it pull.
It was better, but still got up to 210 after 1 spirited run, and driving 65mph on the interstate for 15 still didnt cool it down ANY.
Should I put it back thru the radiator and then thru the cooler?
Or is the cooler big enough? Im struggling.
Thanks!

What RPM are you running while driving around? A 3500 converter is going to put a lot of heat into the fluid if you are driving with the RPM under the stall speed.

So rather than being a jerk about it, I’m going to offer more info. Are you sure the converter isn’t slipping at 1500 when you are cruising?

You actually did solicit opinions by asking the question. I did give some feedback regarding the stall speed and replied to your comment asking if I had launched a car with a stock converter. Sorry you didn’t like my response.

it doesn’t appear to be slipping - just looser than I like.
sorry about the rude response - I’m old and cranky

No worries. I’m trying to not take things too seriously on the internet in 2022. Anyway, I’m a bit confused because first you said it’s locked, then not. If you know what the stock stall speed is, why not get a converter that splits the difference between the stock converter and your current one?
mom really considering going back to the stock converter.
the guy at circle D said that this converter would be great for n/a as well as a centrifugal blower.
from my notes, it’s a 245mm pro series single disc.
ot felt way too loose before the blower and as as much or even more so now.
Only mods are;
longntubes
no cats
npp (oem)
ecs blower
ecs stage 2 fuel E85 setup
fic 1200 inj
its a 2011 grand sport vert. I won’t be taking to the drag strip. I only went with the converter because stick converter and stock tall gear ratio, I could only get 2.0 60’ with my draggy with drag radials - zero traction issues. It would dead hook.
it was faster for sure with new converter but it’s felt too loose since day 1.

ok thats a little strange because i thought they would have suggested their 258mm converter with a blower car? in your discussion did you say maybe it was going to be NA for awhile with the possibility of a supercharger perhaps? anyway i think it may be the converter there was a youtuber recently that had a similar issue converter wise with Circle D
he’s gonna have some explaining to do.
id love to see that YouTube video

I have used that same cooler for years without issue. First location, I had it sandwiched between the IC and AC condenser and it worked fine, kept trans under 200 most of the time. I then relocated it to behind drivers foglight with a puller fan behind it, still no issue but I haven't put near as many mile on it there as previously.
