Hello everyone i am looking to change my transmission fluid but i am a little confused i seen videos where some people change the fluid on a level surface but some jack up the rear so the pan is level? which is the correct way and which way did you yall do it ?

Here's the factory ZF instructions that come with a "brand new" truck specific 8 speed,and they definitely want the transmission level,not the truck.You need the rear tires roughly 8/9 inches in the air to level the transmissions pan rail.
The trucks are the only ones with the transmission pointing downhill ,the cars and every other manufacture that uses the ZF 8 speeds have the transmission sitting virtually level in the chassis,and the majority of instructions are wrote for those applications,as the Ram is an oddball in the world of ZF transmissions,with it's transmission pointing downhill.
Start with a cold transmission,as the ideal checking temp is about 100/105,the 122 is the max checking temp,not the ideal checking temp.I usually drain the transmission while it's hot,let it sit overnight ,then do the fill procedure the next morning when the transmission is cold.
If you let it drain overnight,you'll probably get about 5.5 quarts back into it,so buy at least 6
Go with Johns/Boosted Motorsports video,as he's following the instructions that came with my new 8 speed,and is doing it correct. It took me awhile to get the proper instructions across to alot of guys on here and facebook,lol
