Coundnt have said it better myself!
Vince, I have Reverse and third now. I punched the holes out and what do you know It works.
Only thing is when I shift to 3rd, its in 3rd but takes maybe 2-3 seconds before it shifts. Not slipping pretty much a delay going into 3rd but its still anice and firm shift.

Hey guys, I've been searching and searching, I've seen the end of the web and went back to the beginning again. When I google "4l80e no reverse slipping" every link is purple for the first 20 pages because I clicked it and read it.
I know this thread is about a year old but it's the only one with the answer to my problem...I hope, so I'm resurrecting it.
I have the same problem as described here, I installed a full manual kit from Transgo into a transmission that sat for a bit but was working fine when parked. Now I can only back up on level ground, not on any sort of incline, it just slips.
I bought my kit on Ebay, I may have got an older one that was metioned here. The pics are gone from this thread. They would probably help me figure out what my problem is. Can they be reposted? I don't recall having to punch/cut any holes in any of the gaskets/plate when I did the install.
Which holes need to be cut? I called Transgo today but got no answer, (it just rang). Any help would be very appreciated, I currently have the truck sitting in the driveway with the reverse servo assembly out (its fine, no cracks). I followed all of the instructions very carefully, took my time. I'm sure I have everything installed properly. Another thing, I tore the house apart looking for the instruction I had, can't find them.
Kinda ticked at Transgo right now!
Thanks!
Jeff
