Getting ready to change the tranny fluid for the first time. For the life of me, I cannot find the capacity. From reading threads, I get the impression it is anywhere from 10 to 17 quarts.<br><br>I am planning on doing a complete change as I intend on changing to Amsoil. Anyone have a good figure so I can order the correct amount of fluid?

I never changed mine, but from what I've seen it is somewhere between 5 to 6 1/2 quarts.

Correction to my last post...17 quarts if dry, 5 to 6 1/2 if just changing the fluid.

Just did mine a couple weeks ago. Note, Double Deep tranny pan. Took 16 qts. Drained TC, VB and pan of course. <br><br>~Dave

Thanks. I am going to the Mag Hytec deep pan. Sounds like I will need 17qts for sure.

Has anybody tried the &quot;Trick* of disconnecting the &quot;Hot&quot; line going to the transmission cooler, connecting a hose to it, and running it into a bucket, and then turning the truck on, and cycling the truck through the gears until bubbles start coming out?<br><br>I've heard of this being done on other trannies, but haven't heard it being done on 47RH/47RE/48RE trans.<br><br>Thanks,<br>Merrick Cummings Jr

Everything I have read says to change the tranny oil when it is hot. Why would that be. My 'baby' is my third vehicle and sits for days at a time. When I fire her up, it always takes a bit for the fluid to get pumped back into the TC and I suppose the VB.<br><br>Seems to me it would be best to drain it after a few days since all of the fluid has naturally drained out of those parts. <br><br>Would it be possible to open her up and just let it sit for a couple of days to drain the cooler instead of loosening a line and pumping the fluid out?

Just had mine totally Flushed, it took 16 quarts. But, if you are just dropping the pan it should be about 6 to 7 quarts. Hope this helps.

I removed the line that goes in the rear drivers side, which is the return from the cooler. I put a peice of clear tubing on the line and twisted a peice of wire over it to keep it from comming off. I had mesured the fluid that came out when I droped the pan and put that much in to start. I ran the engine with it in neutral for about 60 seconds at a time. I measured the amount of fluid that was pumped out and added that amount every time. When I was satisfied all of the old stuff was out I put the line back on and brought the fluid level up to the full mark.
