Can a failing injection pump cause transmission no TC lockup? Or any other transmission issues?

Will a failing pump throw codes?

I know my pump is needing some work but can that cause lack of TC Lockup?

Trans seems to work good with no problems or slipping. kinda mushy shifts but pretty normal.

No SES, no Codes that I am aware of.

Thanks!
