I've heard not to do a flush on a high milage transmission that hasn't had them done often. Anyway I was wondering with my new APS transmission should I have it flushed or just the fluid and filter changed? Wanye told me to change the fluid around 10k miles the first time. I'm far from that as I have about 2k on it now but I was just wondering should I get it flushed and have that done everytime or is just changing the fluid and filter a better option?


Also what about my rear diff fluid with the new Auburn LSD. I have around 2k on it too is it okay to let that go to 10k also? I was thinking of changing them both at 10k since the transmission is new and the rear diff has a new Auburn LSD in it. The rest was okay so it was reused.

 

Call Wanye and get his opinion, if he's covering the warranty on it, do it his way so he doesn't have an out if anything goes wrong (not that I think he'd do that, but CYA anyhow.)

While talking to him mention that "Myth" about old trannies and flushing (that sounds like a really bad movie, heh) and see what he says. Love to hear the opinion of someone who's respected for "bulletproofing" these things.

 

I bought my truck at umm 104k miles and the first thing I did was a flush...no problems from what I can tell.
