You managed to get the Demand Drive Plus. Get the Polaris AGL for the tranny. If not I would hate to see your next post as a Polaris hater because your transmission grenade's. I just made an 80 mile round trip to pick up fluids. Don't guess I'll miss that hour and a half of my life too bad. Just don't want you to have problems down the road caused by the wrong oil.
You do understand that the AGL is in the family of gear lube 75/90w and such. The transmission oil is oil not gear lube. Now there is a AGL plus and that is different. Crack open a container of the XP trans oil and compare it to AGL and AGL plus.
I'd hate you to run what the dealer tells you and it be wrong like most of the stuff they say. We can't always just use blind faith, we have to figure it out by understanding it. Polaris does not make oil. The make labels.
On the note of the DDP fluid. I had a Chinese SxS. A wolverine 800 4x4. It used a Hilliard type front diff. That's why I have the DDP. There is no other readily available fluid to sub it out.
Hell, my Polaris dealer gave me the wrong spark plugs last week for their top line ATV. TWICE! The 2ND time I just asked to see if they would do it again. Clueless.
You are quite correct, mistakes are common place after all we are all human... Ultimately the responsibility rests with the installer to be sure the product is correct.
Concerning the oil, you asked, we responded.
Do a search, this has been hashed over ad infinitum. If you do not like the advice, don't take it. that's the beauty of the forum, you can pick and choose who you listen too. Also much like going to different docs for second, third and fourth opinions, you WILL eventually fond someone to tell you what you want to hear...
I agree, Polaris does NOT make oil, they have it made for them. If your thinking, they could simply re label something else already in production for a different application. They could also just as easily have it made specifically to there specs and it could be different enough to cause problems too...
To my mind, the cost and difficulty (Or lack there of) in attaining the factory product is a MOOT point. Unless the buyer simply likes to complain. Anyone can get these items shipped directly to there home/business if your too far to drive to get it themselves. They are available at a myriad of dealers on line or thru EBay.
I have read on other forums of a substitute, I have also read of tranny failures associated... To my mind why chance it?? I paid allot of hard earned $$ to get my machine, why quibble over a double-sawbuck?? All this over a 20$ bottle of fluid that works for multiple oil changes!
