Small Engines (Lawn Mowers, etc.): poulan pro 16 hp 42in cut, transaxle, toast

Question
what type of oil goes in the transaxle as I feel it needs changing as it has slowed down on pulling

Answer
The Truthmeister will answer your question even if no one else will.
The transaxle is toast. Scrap the tractor.
When you don't get your question answered it's because the expert is worried about his ratings.
I just tell the truth and let the ratings fall where they may.
