m1008 tranny added 7.3 quarts still not filled up?

[maxpanic]

So I have an odd puzzle. I took the pan off the tranny and drained all the fluid. Then I put the pan back on and as the FAQ says I added 4 quarts of dexron III. when I turned on the engine and measured the level it didn't even show on the dip stick. I added another 3.2 quarts until I ran out of tranny fluid, I have to go buy some more tomorrow I guess. I this really possible or have I fouled something up? I will quickly be up to 8 quarts for the tranny and then who knows?

IIRC 8 is close to the # on a th400

So in the CUCV FAQ is this wrong?

Transmission (TH400, 3-Speed)

• Transmission fluid was indicated as Dexron II. This has been replaced with Dexron III.
• Transmission filter is NAPA# ATP14558 (or 19701 w/gasket); FRAM# FT1020A (w/gasket)
• It only takes 1 pt. to raise the level (hot) from “add” to “full”.
• Capacity is listed as 4 qts., but this may vary. Fill as needed to reach level.
• Drain/Fill and replace filter every 2 years. Do more frequently if regularly using off-road or for towing

A completely dry TH400 (new build and empty converter) takes about 12.5-13 quarts. Subtract 3.5-4qts for the converter and valve body. You're close, don't worry.

When I dropped the pan on my M1008 for a filter change, it took 7.0 quarts exactly after refilling.

Mine took just under 2 gallons. Gotta remember, it can only take half a quart to be completely on or off the dipstick. Every truck has its quirks.

Same here. The three th400's I have pulled the pan on in the last year all took 2 gallons or a hair less to fill back up.

Took me almost 8, I didn't do the converter or anything just dropped the pan and filter.
