Very nice! Be careful flaunting that Dinan stuff though. e39 guys are weird about it.
Why does the one guy in the first pic hate BMW's so much? Maybe he's a really good guy otherwise, but it might be detrimental to the friendship if you hang around that hatred.
I'm curious why you say that. I'm a huge fan of dinan. But I'm also not an e39 guy. Unless this guy crashes it and I buy it

sweet car! welcome.
I have purchased a e39.
I figured I need something a little more reliable
more reliable in that 1) it breaks less or more reliable in 2) overall maintenance cost? a BMW 5 series is #1. a replacement 6 speed is about $1000 for the 540

I've been primarily involved in the e39 M5 world, but there are a lot of guys that will literally ejaculate all over a Dinan badged car. To them Dinan is the epitome of automobile evolution and technology. They actually become angry when they realize they can't buy Dinan tires or gas for their cars. It's really weird and irritating. What I've experienced is that Dinan stuff is good, but wildly overpriced and only first because they get first had touches on new BMW stuff through BMW factory......so of course it will be first. They charge a premium for that.
So, if you come out to your car and there is white crusty stuff on the rear end, you know what it is.

I found a dealer receipt for all the dinan stuff thats on the car. It was all installed at 300-600 miles. I thought that was pretty rad. It was like 3 grand I think.
We have all the receipts for the car and the guy easily spent at least the cars value in maintenance.

That's cool. A well maintained e39 is always nice!

Nice find!

I figured id update this thread because @DSMDane Doesn't know how to keep ontop of things.
Last week Thursday we picked up a replacement transmission for 600ish dollars with 80k on it. I think we are going to swap it over the winter.
Any E39 guys have a suggestion on what type of fluid we should put in it? Alot of these 420gs have a sticker that says ATF only. But the one we bought says MTF.
Ive heard alot of people with the 420g use Royal Purple Syncromax and swear by it.
Anybody care to weigh in?
-
Factory fill requires MTF-LT1/2.
The internets suggest:
Royal Purple Synchromax or BMW MTF-1
Red Line Synthetic MT90 is a mystery, It seems like some guys are hesitant others suggest it. There were some supra guys were running this in R154's and V161's and discovered that it was causing an internal component to swell and fail. I would personally run RP.
-
great deal on that trans!
-
Snap and I have both had bad experiences with previous owners using royal purple. Redline solved problems for both of us.
Well suck me sideways lol

+1. royal purple and my zf310 did not match well. it felt like shifting through peanut butter - particularly worse in cold weather.
-
I used RP in my ZF320 and it was scary how smooth it was.
I'm stoked to see a nice looking 540 on here! Congrats on the purchase!
