700r4 slipping in cold weather

What are the results of your pressure test?

Did a little work on the transmission today. Did a shift kit, filter, and changed all the fluid. Now the truck is at least drivable. Before it would slip in 2nd to 3rd and 3rd to 4th. Now the 3rd to 4th is completely fixed and doesn’t slip at all. But the 2nd to 3rd is still doing it. This is telling me it’s got to be something that just needs to be adjusted now but that’s just my guess. It’s not a really bad shift either. Slips for about half a second then kicks right into 3rd. Also when dropping the pan it was pretty clean. No chunks of anything in it

Again, what are the results of your pressure testing?

Stop guessing and do a pressure test so you know exactly where you stand. Let us know the results whenever you have them.

What did the spacer plate look like? Anytime I have a 700 or 4L60E apart, I plan on replacing the plate. The check balls beat the plate pretty badly, sometimes they get do worn out the ball actually gets stuck in the plate.

If it still slips, it’s going to get worse. As nick suggested, a pressure test would be the next step.
