whats the best t20 tranny fluid to use

[mgl6x6]

I see lots of post saying some guys use type f pluss the additive for the slip was thinking of changing mine max is a 2007 max iv 27 hp kaw engine very low hours less than 6 purchased machine from a guy never used it only had 1 hour run time when i got it only rode it once i probably dont even have to change it but would feel beeter doing it because of sitting .what type should i use ri said use type f but was just seeing what other riders are using . Will the new synth fluids be better? Ill probably use a oil sucker to suck the old out and measure the amount that comes out so i refil the same amount.

i have tried about everything I can find for fluid and can't tell any difference. At this point whenever I build a T-20, I grab whatever type of ATF catches my eye at the store that day and a tube of TRANS-X limited slip additive. Amazon.com: CRC 402508 Trans-X Posi Trac Limited Slip Gear Oil Additive, 7 Fl Oz: Automotive then I label the T-20 with whatever went in it the first time, and stick with that on subsequent changes. 4 oz oz trans-x, then ATF till it just runs out the lower plug. Whatever you pick will be fine, but if it is different from what was in there it might act funny. In that case I've done 2-3 fluid changes with a little run time between and it seems to clear up.

\To drain the fluid, I run the machine up my ramps to the bed of my truck and block the rear tires when it is as steep as possible (Note from the department of redundancy department : a helper is very helpful to do this) then pull the drain plug on the trans. Once drained, pull the blocks and let the machine roll down, then refill on level ground.

another helpful hint. Steal the GLASS (2 cup) measuring cup from the kitchen when your wife isn't looking ( then deny any knowledge as to it's whereabouts) (Side note... dinner might suck till she buys a new one) Measure 4 oz of transex, then add ATF till you have a quart total. pour that into the the T-20 and your good to go. Why glass you ask? cause most fluids used in the shop will break down a plastic one and turn it so murky that you can't read it. (second side note: DO NOT under any circumstances return the measuring cup to the kitchen!!!)

I'm the guilty party that has been recomending the synthetics......I do agree with R13 about the fact that any fluid will work, but I'm guessing the synthetics will last a little longer. Thats really not a big deal if the fluid gets changed often enough, but many machines do not have hour meters and people tend to forget(me)
As the fluid wears out the clutching (drums slipping in the bands) will become grabby.
If that happens, just change the fluid, it's cheap. So the synthetic is probably a waste of money, but it's such a small amount that I'm gonna keep doing it.
