i intalled a b&m tranny cooler. its the model 70264.


whats the capacity? how much fluid should be in my tranny?


i did this math: when the dealer flushes your tranny, they put in 10 7/8ths quarts of J fluid in. im getting my tranny flushed on monday, but how do i know how much to tell them to add in?

 

with the added hose and cooler. you are looking at maybe 1 quart.

 

shouldn't the people flushing it know? I got B&M coolers too

 

Hopefully even an idiot mechanic knows to refill low and allow ATF to heat up [to 174F] then zero in to perfect using the special dealer dip stick.

 

i would also hope so.

 

When I had mine on, it didn’t hold a whole lot more than without... less than a quart...

As Q45tech stated - add what the manual says plus a little... get the fluid to temp and check the dipstick... I can’t remember the model number of the ATF cooler I have, but it’s a B&M also... I would guess 1/2-1 quart possibly...

 

im getting my tranny flushed tomorrow, so ill let you know what happens then.

 

you'll be ok lol....

 

i hope so.

 

I have the B&M 70297 & that thing is a beast, it holds at least a quart.
I installed the one you have on a friends and it took about 1/4 quart

 

no it takes more than that.

 

Well you had it flushed and filled and now it is fine. So dont worry it doent leak and its a sealed system.

 

^^^ as long as the return line doesn’t blow off... happened to me when aggressively downshifting at high rpm, 5th to 3rd and line blew off - dropped fluid all over the fwy and had no gear... tranny held up though.

I'm not certain if the cause was downshifting or if the hose clamp was loose (or combo of both)... there isn’t normally much line pressure so who knows.

It spooked me though - I took it off the next day and haven’t run with it since... I plan to re-install eventually though. I wish we had threaded connectors.

 

yea im gonna look down there and double check that everything is tight.

 

Sick work so hows the boooost feel with the new blower and fixed tranny
