Any suggestions on synthetic ATF? Would doing a flush with synthetic be safe? Have heard doing a flush may cause problems... Thanks everyone

 

A flush isn't necessary. Many just drop the pan, change filter and refill. This only removes about half of the old fluid so many do it again in 10-15k.
I did have mine flushed and haven't had any problems. Of course getting as much of the new fluid in there as you can, the better.
This is our ATF+4 fluid: ATF
I can get you pricing if you wish.
