Some members are being proactive and changing their fluids early AUF because of past posts describing some pretty nasty stuff being drained from the angle drive. But you already knew that didn't you !You have enough miles for the (ACTUAL) need for a change??? Wow!
"Nasty" is pretty subjective. Any ACTUAL lab analysis of said liquid???Some members are being proactive and changing their fluids early AUF because of past posts describing some pretty nasty stuff being drained from the angle drive. But you already knew that didn't you !
Shiny little metal slivers (no need for analysis) metal slivers is metal slivers ! And sense it's been said by Polaris "the final machining of the angle drive gears is done during break in" I have to assume the slivers are coming from the angle drive gears."Nasty" is pretty subjective. Any ACTUAL lab analysis of said liquid???
OK, you got me worried, (a good thing), to where I had not considered how manual transmissions and differentials differ, (GL-3 is specifically for transmissions, GL-4 and GL-5 are for differentials, as I understand it?), and I slipped back in doing more research on the topic to where I was getting ready to dump the purple stuff and install dedicated GL-3 lubricant in the tranny. Then I came across the empty bottle of Royal Purple and stopped to read the label and I quote, "Important Notes: Max Gear is non-corrosive to soft yellow metals (brass, bronze, copper). Safe for use in manual transmissions with Synchronizers...................."Bill, is the RP xmsn oil rated GL-3 that is called for in the manual? I've been thinking about changing mine down the road and there's not many after market oils with that rating anymore; however, Polaris does package quart containers of synthetic GL-3 for about
$12 per quart so I think I will use that. From what I've read, the newer stuff, GL4/5, can be harmful to synchronizers (I think that's what I read) in our type transmission.
Oops, it appears that I may have given a bit of false info here, even though on the bottle it states "Pennzoil Syncromesh MTF is a manual transmission fluid and gear oil with API GL-3 level performance," a friend contacted Pennzoil to confirm and this is the response that he got,Old thread but I may have found a couple of other options for gear oil for the transmission that I do not believe have been mentioned yet? In researching transmission oil for our Jetta I came across recommendations for AC Delco Synchromesh and Pennzoil Synchromesh. I recently purchased the Pennzoil where it has smoothed out our Jetta tranny quite noticeably and on the bottle it states to be a GL-3 equivalent. It is also significantly cheaper than most of the other alternatives mentioned.
The only one that I have found so far:I have searched high and low and the only certified GL-3 is the polaris stuff which is it causes me great pain to use polaris oil in the tranny but everything else would absolutely void the warranty if anything were to develop down the road.
The valvoline would work but the AC delco is not synthetic so it would "void" your warranty.The only one that I have found so far:
SynPower TDL 75W-90 - Manual Transmission and Axle Oils - Valvoline
I just chanced across another: Amazon.com: Genuine GM Fluid (89021806) 75W-90 GL-3 Manual Transmission Fluid - 32 oz.: Automotive
Well, I am not so sure about that, this is transcribed straight from my Owner's Manual on page 54, "Always use SLINGSHOT Transmission Fluid or another GL-3 rated transmission fluid." I do not find anything stating that it has to be straight synthetic? And, if I am not mistaken, beside the filler hole of the transmission does it not state GL-3?The valvoline would work but the AC delco is not synthetic so it would "void" your warranty.
