4L80e install - Questions

Hello? Is this thing on? ;)



I really could use some help here.

The car acts like my old TH400 would act if you were low on fluid. I can drop it in reverse or drive, take my foot off the brake and the car will move. However, if I apply any throttle it's as if the thing is slipping with little to no change in how the car moves.

I've got 13 quarts in it now and the fill for one with a stock converter is 14. Surely it's not low?

Before everyone asks, I have the Lokar firewall mount dipstick and the darned thing has show over full even at the 10 quart level. I don't trust it much at this point. I did check the level after having run the car for a while, with it in park and I did cycle through the gears a few times just for good measure.

Since I have the latest TCI TCU software, I had the ability to do data logging. I did a short log and ran it through a few gears. One thing I notice is that even with turbine speeds (I'm guessing that's referring to the converter) of 1000 rpm the line pressure it is logging is at 60 (PSI, again, guessing 'cause I'm new to the software) never changes. I do see the logged gear changes. I also see the TPS reading change where I hit the gas.

Any suggestions are welcome.
