I wanted to instal my fully assembled pump with new gasket, lip seals and O-rings, but then I noticed this... Is this normal?
It doesn't seem right to me... (Broken?)
I looked up the part buit I'm not sure of the name. Is it the 'intermadiate wave plate'?
Can I just assemble it and leave it like it is or should it be replaced anyway to avoid future damage?

The intermediate wave plate should be a solid, continuous piece without a slit or break in it. It is supposed to be "wavy." This cushions the impact when the intermediate clutches kick in, and produces a smooth shift.
Are you concerned about the wavy, non-flat appearance, or about the slit..? I can't see the slit having any impact on the wave plate's operation. It could produce a slightly softer and smoother shift. I stopped working on TH350 trannys in the mid '70s, and have not seen a "split" wave plate during my time building TH350s in the early to mid '70s.. It could be possible that Hydramatic introduced a split/slit plate in the later '70s that I am not aware of in order to smooth out the shift, so I would not discount the split plate from being legitimate. The waviness, however, is correct and legitimate.

We did the same thing on our racing transmissions. Most people with brand new Chevy Caprices and secretaries with a new late-'70s Vette did not appreciate that "performance" upgrade...
Yep. When I did the T-400 for my old 427 Camaro...I literally sat down with the GM manual and traced all the circuits through the trans. I discovered that just about everything in there was to "calm down" the shifts. So of course I defeated most of them.
That sucker produced high gear chirps at barely off idle throttle that jarred your teeth. Full throttle rattled the whole car.
I then went back home and reimplemented a few things to make it street drivable! LOL

As noted, I've never seen one with a slit in it, either, but I don't see how a slit would alter it's intended function other than perhaps making the shift a little softer by making the wave a little easier to compress.

Th350 wave plate?
