Hi
I've read and watched lots about changing the transmission fluid in my 2014 Ram 1500 with the ZF 8 speed but I still have a couple of questions.
Do I drain the fluid when its cool or when its between the 30-50C (86-122F)? One video https://www.youtube.com/watch?v=kXK...Ds9wMi6TZg&start_radio=1&rv=kXKhZievmSI&t=924
said to drain it when its below operating temp but I thought I also read to heat it up first. Does draining it cool keep the fluid out of the tranny cooler so more comes out? Once comment in the video said to drain and then run the engine to get the oil out of the cooler - this sort of sounds reasonable - needed? Dangers?
This video talks about how to make sure you have the tranny full to do the regular fill procedure then drive the vehicle until its hot, let it cool and then do the fill check procedure again. This is to make sure the tranny cooler was full too. Needed?
The last thing I'm questioning is how to do the rev to 2000 part of the fill procedure - is this in park or neutral? Does it matter?
Thanks for the help.
