The question is this:
Transmutation as a trait states that it alters the form of something (to varying degrees). Polymorph is a specific instance of Transmutation, and Polymorph specifically says any polymorph effects attempt to cancel each other out.
However, what about Transmutation and Transmutation? Or Transmutation and Polymorph? Say if a Druid wants to cast Fly on herself and then on the subsequent turn cast the focus spell Wild Shape and change into a bear. Can she then benefit from the first Transmutation effect and her new Polymorph?
Further, if the bear has a different speed than her base (for simple maths let's say base is 25 feet and her new bear is 30 feet) does her Fly spell only give her 25 feet of flying (since it's 20 feet or base, whichever is greater) or 30 feet since her new "movement speed" is 30 feet?
I don't see anything that states you cannot be under the effect of multiple Transmutation effects, only the instances of Polymorph. However, wouldn't a form-change still interact with Polymorph in some way?
RAW it looks like no, but I want to say that you couldn't cast Fly (or other transmutation effect) and then slap on a Polymorph effect (Animal Form, Pest Form, True Polymorph, Baleful Polymorph, etc) and gain the benefits/drawbacks of both? This sort of affects Alchemists' mutagens.
Morph spells also may be affected:
Your morph effects might also end if you are polymorphed and the polymorph effect invalidates or overrides your morph effect. For instance, a morph that gave you wings would be dismissed if you polymorphed into a form that had wings of its own (though if your new form lacked wings, you’d keep the wings from your morph). The GM determines which morph effects can be used together and which can’t.
but Transmutation spells that have neither Polymorph nor Morph traits are unaffected. As I imagine, they give enhancements independent of form (like Ant Haul), or they really affect its surroundings of a creature (for example Fly spell affects the air around the creature), or so they don't end when the creature is polymorphed. And of course transmutation spells that manifestly affect the environment (like Entangle) are unaffected.
All Mutagens are Polymorph effects.

I guess that's the point - what transmutaton effects you can use with mutagens.

Any that don't have the Polymorph or Morph Trait. Those that have the Morph Trait, it depends on what they do.
Transmutation is just a Trait that identifies the spell's School. If it isn't Morph or Polymorph, it isn't impacted by those at all.
Heck, not even all spells that seem like they alter your form are Transmutation spells. Barkskin is Abjuration.
