Re: [DML] Re: stage II - Automatic?



This info could not have crossed my inbox at a better time. I am about to
pull my engine and trans out of my D, hopefully Sunday. The only reason I
have decided to pull the trans is because I want to clean it up a bit and
change the fluid and filter, and maybe some of the seals depending on how
things look after i get it out. I have an Eagle PRV thats going to be put in
which is freshly rebuilt soon as i get the shims from Volvo and the B280F
cams from a Volvo repair place.

I will use syn fluid in my trans now.
How many others agree with removing the kick down cable?
I will work on an idea for the fluid cooler, when i get one I will be sure
to pass it along.
