View Full Version : How much Tranny Fluid for pan drop change? 14 or 5 quarts? 302Xplorer 03-06-2009, 10:27 AM I am about to change my transmission fluid and have conflicting info in regards to how much to purchase. How much is needed if you were only going to drop the pan, change the filter and refill? I have the 4r70w tranny in my 2000. Thanks Maniak 03-06-2009, 10:32 AM I can't say for 100% sure since I don't have that trans.. But.... On an a4ld AND 700r4 which are two completly different transmissions (ford and chevy), when I do a pan drop and replace the filter I only loose whats in the pan plus what was in the filter. For us its been between 4 and 6 quarts.. Therefore.. I doubt very much that is 14 quarts since that is about the total fluid capacity of an automatic transmission and your not emptying the torque converter when you drop the pan. ~Mark 302Xplorer 03-06-2009, 10:56 AM Hmm... How much should I buy, just in case? Maniak 03-06-2009, 11:07 AM If you can buy it by the gallon, just grab 2 gallons. I always buy it by the case (12 per case) and try to keep a full case or more at the house.. Sometimes its cheaper that way plus its a 30 mile round trip to the closest auto parts store, so I try to keep things like that at the house. ~Mark 302Xplorer 03-06-2009, 11:25 AM If you can buy it by the gallon, just grab 2 gallons.

I just ordered a case (12) of the Amsoil Synthetic Universal Transmission Fluid. We'll see if that gets her done. Thanks for the help! 410Fortune 03-06-2009, 11:29 AM the 5.0L 4r70w converter has a drain plug, with the pan and filter drop you will lose 4 quarts, draining the converter will lose another 2 quarts 6 quarts should cover the pan and converter drain, I usually buy 8 just in case, and I blow out my trans cooling system lines at the same time good time to put a drain plug in your pan also, so you can swap out 4 more quarts in a few miles and try to use all 12 or your amsoil synth 302Xplorer 03-06-2009, 11:40 AM good time to put a drain plug in your pan also, so you can swap out 4 more quarts in a few miles and try to use all 12 or your amsoil synth True. It would be the perfect time to do so. |
