I wouldnt mix them, if your not gonna do a complete flush then just put regular tranny fluid in it. save some money, cause just a couple of litres of synthetic wont make a big difference.

 

ive been told not to switch the fluids it can burn a transmission rite up, if your worried about heat get a bigger transmission cooler...

 

Allright, So here is the real deal.. I wanted to just change my filter and put fluid it. So while i was takign the pan off, one of the bolts didnt come out it was stripped. So I got it all back together, and put in the fluid and realized it was full synthetic... But from what you guys are saying maybe i should take it and get it flushed, and just have all one thing in there....

Or do you think it wont be that bad if i keep it in... for like another 30 thousand miles?

 

it shouldnt hurt it. since its only like 4 litres it will bea synthetic blend I would just to a complete tranny flush next time.

 

i dont think it would mater if you blended or not, all you need to do is make sure you use the correct type ATF and the correct amount.

 

anybody have the steps on how todo a full flush yourself? im gonna be doing a fluid and filter change and would like to do a full flush. Do you guys reccomend doing a band adjustment if i already have the pan down? thnaks

 

let the pros do the band adjustments

 

band adjustments are nothing to be intimidated by. if you have an inch/lb torque wrench your in business. the specs are in any haynes or chiltons. for my old ram is was 72in/lbs and then back off a 1/4 turn. The rear band is a little harder to get at, but its for reverse so its not as nessessary if you cant reach it.
