I changed the tranny fluid once before but I can't remember how many Qts. it took. Its a 700-R4. I plan on ordering some Red-line today and want to be sure I'm getting enough. Also I'm installing a B&M tranny cooler at the same time, do you guys think ordering one extra QT. will be enough. I'm pretty sure it will.

 

come on I know someone here has to know how many qts it takes to fill a 700-R4

 

I beleave that it is 5 on a serves. 12 on a new trans
hope this helps

 

5 qts is right for the service, i would expect the external cooler to take around 2 so i'd say get 7 total
