Anyone know what trans oil I need to use on a
ZF6HP26
GA6HP26Z
The stealer are reluctant to give that info.They want $875 CAD just to change the oil.I'm no idiot.I use to be a licenced mechanic.So paying close $900 CAD for a 30 to 40 minute job that I can do myself is just insane.
Can't find any info on what oil to use. Could use some Xoutpost members help?

Not buying the oil from the stealers.

Thanks in advance.
