I have a 2006 Dodge Grand Caravan 3.3 liter V6 with front and rear heat and front and rear A/C. I need to replace my A/C / Transmission cooler combo unit because it is leaking Transmission fluid pretty badly and I need to know how many pounds of R 134a Freon will be needed to recharge my A/C when finished?

Thanks

 

Should be on an underhood sticker somewhere. Moved to the correct section.
