Default 4l80e wont do anything!

I'm done with the swap and now it will not do anything I pulled the cooler line off to see if it was pumping fluid and the trans is not pumping fluid so i dont know whether when i took the pump apart to put the spring in from p.i I pinched a oring or what i would think if i did that t would still pump a lil bit i just checked the distance from the bell housing and the converter pads and it's right at 1" so i dont think it is the converter anybody have any suggestions before i pull the trans out and take the front pump back apart?

nothin i took the front pump out and put the converter limit valve spring inside the one that was in it already justy like p.i instructed and then put a new gasket on the back of the pump and new oring around the pump and on the od shaft and bolted it back up. then i put the converter on the shaft and spun it till it clicked 3 times and bolted it to the motor then bolted it to the fly wheel and measured to make sure it was the right distance between the bellhousing and converter pads.

If your not pumping fluid at all its either the pumps broken or possibly the regulator valve has popped out not to many options

iI have never seen a 4L80E that you put the convertor on and spin it till it clicks 3 times????? All I have seen are you have to install the converter with the 2 flat spots line up in the pump!! I may be wrong, never put a PI converter in one but...

Sometimes if you do not get the clip all the way installed in the groove it happens. Good to hear that you found your leak. Vince

i got it fixed then i drove it about 20 miles and it was driving fine till i pulled up to a stop sign and it will not pull off from stop signs anymore i'm just going to put a new front pump on it and see if that helps i think i hurt the stock one when was trouble shooting the no pressure problem.
