47re Problems after rebuild

[fire176969]

Just rebuilt my 47re and have a couple problems going on. It is slipping with the TC locked, no matter in drive or overdrive. Fluid level keeps going down with no leaks and not going into the antifreeze like a cooler is blown out or something. I have already put 16 quarts of oil in the transmission and it is showing a quart low again. Just put in a stock overhaul kit, a shift kit in the valve body and a single disc billet converter. I'm kinda lost for where to go next other than keep dumping fluid to the thing until it quits going down.

It will expand, the fluid that is. Your converter holds a few quarts. I would get it up to temp and drive it. Take a few quarts with you and go 5 to 10 miles pull over and check it. Go some more than do the same.

I have been doing that. It first showed full at 12 quarts and have added 4 since then. I can't seem to find out if the amount of fluid is even close to normal. I've never had an auto have fluid level change so much before.

My tranny is funny like that also. I can drop the pan,do a filter change start it up ,fill it to the line drive and when it gets hot i only have 1/2 of the line covered.

Should have just put the 13 speed in the thing and got rid of the auto. Oh well, next time when I'm not so

Yeh you need to add more fluid I think mine holds close to 20quarts but I have a aftermarket cooler and 1/2" hydraulic lines for cooler lines, but I think a stock fillup is 18 quarts
