sprinklerman Posted October 12, 2013 Report Share Posted October 12, 2013 ^ Why I don't like ATF. It is a good fluid for wet clutches and transmission, but you have to keep it cool. The second it gets hot it breaks down fast, which can glaze over your clutches. And let your bearings gald. Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted October 12, 2013 Report Share Posted October 12, 2013 Has anyone actually tested there ATF after 1 ride then after 1000 rides? I find it hard to believe my over powered weed whacker will break down trans fluid faster then the 120k miles on my truck. I've towed through the sand, up mountains, in the mud, at 80mph. Same trans fluid. Does anyone have any actual facts of type F breaking down in 3 hours? Quote Link to comment Share on other sites More sharing options...
sprinklerman Posted October 12, 2013 Report Share Posted October 12, 2013 Once it hits a certain temp ( cant remember what it is off the top of my head) it breaks down real quick. Its not the miles ,its the temps. Plus the heat breakdown is cumulative. Cars definitely have superior cooling systems to stabilize the temps over a banshee. As far as how long it lasts,,i have no idea. My solution is to run a fluid that's more heat stable than ATF,,since upgrading the trans cooling on a banshee isn't much of an option.

m671054 Posted October 12, 2013 Report Share Posted October 12, 2013 Loads on gears and bearings in an auto car trans are totally different then a banshee. only reason to consider it is if your always tearing the engine down like on a drag bike.

sheerider11 Posted October 13, 2013 Report Share Posted October 13, 2013 The planetary in a automatic is a constant mesh and constantly spinning. Bearings I can see since there is no side load. But between how hot the automatic clutch packs get, the bands, the torque converter, and the weight it can move. I'm still seeing it hard to believe my quad is breaking it down in a few hours. Has anyone done any sort of testing? Be it temp, viscosity, actual lab test? I'll take anything. I'm just thinking out loud, so please if anyone has actual facts please shoot me down. If not I would like to keep the ideas going Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted October 13, 2013 Report Share Posted October 13, 2013 Im going to have my new builder inspect my trans and wet side under the cover. Ill keep using cheap sstuf if its all good. I dont mind using expemsive stuff but not if its a waste. Quote Link to comment Share on other sites More sharing options...
J-Madd Posted October 13, 2013 Report Share Posted October 13, 2013 It seems to me that the ATF doesn't disperse contaminants as well as conventional oil, but I could be wrong. When it starts looking cloudy it may start having shifting problems. Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted October 13, 2013 Report Share Posted October 13, 2013 I run Advance Auto Parts 10W40 in ours. We've never had a problem. I do believe our overrides are among the best available also. Quote Link to comment Share on other sites More sharing options...

Ive also ran Klotz Flexdrive with good results,but the 15/40 did just fine and is more readily available. Quote Link to comment Share on other sites More sharing options...

If not I would like to keep the ideas going Don't know where you came up with it breaking down in a couple of hours. Wet clutches are made to slip, slipping casues friction thus causing heat. The steals between the frictions in your clutch are what heat up. ATF is designed to run at an operating temperature of 175 degrees, 20 degrees more will cut the service life in half. In car the fluid is circulated and cooled, not to mention there is much more fluid in the system. In a banshee there isn't that much fluid, and it never gets cooled. So when your hot lapping your drag bike launching at 8k, when you stop and take off again, etc your clutch is slipping and heating up the steals and oil. The last stock clutch setups I have torn apart recently had discolored steals, both on alky drag bikes, one with lockup, the other without. The one without the lockup was slipping when I pulled it, steals had bad discoloration. Quote Link to comment Share on other sites More sharing options...
bebetekbanshee358 Posted October 14, 2013 Report Share Posted October 14, 2013 I'm not a big fan of the atf. I run motorcycle oil.. don't run engine oil becsuse engine oil has friction modifiers .. Quote Link to comment Share on other sites More sharing options...
camatv Posted October 19, 2013 Report Share Posted October 19, 2013 atf FUCKING SUCKS simple as that. it creeps, it breaks down and you loose your lubrication. bearings suffer, internals suffer, clutch wears the f out fast.. 220 degrees and it turns to water. if you cannot afford a 5.99 each qt of castrol 4t 10-40 MOTORCYCLE SPECIFIC oil you got problems. the castrol should last about 4 RIDES and i mean full on dune trips runing 3 days +. i change it when i can see a small amount of discoloration OR the bike screws up on a few shifts.

special06shee Posted October 19, 2013 Report Share Posted October 19, 2013 Shifter location is key. On my pro modded trans i never had a problem shifted whatsoever regardless of what trans fluid i had. At the recent hq ride i was having alot of trouble shifting the bike while drag racing(something i usually dont do) tyler pointed out my shifter was a bit to low. I made the change and bam o... The bike shifted like a dream. The shifter has to be at the correct height so your foot COMPLETELY disengages from the shifter to allow for the engagement of the next gear.
