Hello guys making a new thread here , my newly installed 4l80 has line pressure but won’t move in any gear , feels like it engages and try’s to move in that direction but feels like I have 6000 stall and only moves a inch , I’m concerned the converter is bad anything I can do to confirm this (stock stall )

line test :

park 60psi

reverse 115psi

neutral 60psi

drive 80 psi

 

Those idle pressures look good. However it would be nice to see the same pressures with a 2000 RPM Stall & the case connector un-hooked.
I can only think of 1 or 2 scenario's that would give a no-move forward or reverse and still have pressures.
1st is a bad converter
2nd is a broken input shaft/output shaft
Everything else should give at least forward or reverse.

 

If your Vehicle is Four Wheel Drive...

Your Transfer-Case is probably in Neutral.

 

It is 2wd and I will test line pressure unplugged tomrrow and also will try to feed it more fluid since I lost track of how much it ate and spilled, will stalling it at 2k with forced max line pressure tell us something ?

 

It should take 13-14 qts. with a new converter. I have had many 4L80E customers stop at 10-11 qts and call about it not moving or acting funny.

 

OMG!


Hmm... I Like actually, Like really, Like havta' put Fluids done in dere' ?


...Or she Like, done Won't be movin' none, Like actually ?
