They will mix just fine. I was told if I had a hard time seeing the fluid on the dipstick just add 1qt of regular fluid to add color.
I have not had any issue's.
You can completely flush your tranny and converter by first drain/remove pan and change your filter and put the pan back and fill with the fluid you want and remove the return tranny line and put a bucket under it and start your engine and let it pump out the fluid into the bucket until you see the clean fluid (you can tell when the clean fluid comes out) if it starts to run out of fluid shut motor off and fill back up.It is best to have someone help so one can start the motor and one can watch the bucket.This totaly gets the old fluid out of the converter.
Went to the local farm supply got some tractor trans-hydraulic fluid. Hope I got the right stuff, does it have to say non-foaming or just say trans on it ?
i've been using jd low viscosity hy-gard. it's the replacement for type f fluid that used to be run in the older hydrostatic lawn tractors and skid steers. for me, it's pretty cheap cause i work at a john deere dealership so i get it at cost 8)
