Do not use Redline Heavyweight Shockproof for Rear Diff if LSD?

[4gfun]

I was reading something (I think it was on Jack's transmissions) not to use Redline in an EVO III LSD.

I guess that I don't have an EVO III LSD, but I do have an LSD. What is the difference between the two? I can tell you that I have a 3 bolt LSD.

Just want to make sure that I don't have an EVO III LSD since I already have Redline Shockproof Heavyweight in there!

Thanks

Why do they say not to run it?

Says something about the clutch packs becoming non-functional. So I guess it basically just turns it into an open diff? Just use mitsu diff fluid and don't worry about it.

So are 3 bolt LSD's considered EVO III LSD's? Which are...want to know if I am safe?

Took me 4 hours to get that heavy ass fluid in there!

Also took me many many hours to drill the old drain plug out and replace all of the bolt covers with new ones.

Rear diff is noiser now.

Hmmmm

The Evo LSD is different as its a clutch type lsd and they will be soaked in whatever fluid you put in. The 3 bolt rear end has a viscus coupling. Its a sealed unit and wont be effected

Thanks for chiming in. I forgot that it was sealed.

Yep yep! And FWIW, I've been running the Heavy Shockproof in my rear for like 4 years now. No issues.

After reading their excerpt on shockproof, it makes me wonder. I swear that I read, just last week or maybe the week before, that someone on here was instructed to use a shockproof blend in their brand new shep trans. I don't recall the details but it was likely 2 parts MT-90 and 1 part (or less) shockproof.

It seemed to be under the guidance of shep trans inc.

That's what I was told to run in my Shep stage 3 trans and now I am second guessing it. 2 parts MT-90 and 1 part lightweight shockproof.

I know its off topic, but I haven't read that page before on Jack's website and I think it warrants some discussion. Maybe another thread and some input from Twicks69 and other tranny gurus I don't wanna hurt my built tranny. This is my 5th trans in 2 years and I finally sprung for a built one!!!

 

[PieEyedPiper]

Ah! Maybe it was your posts I was reading then?

I don't think it's too far off topic, but this subject is of much interest to me. If you start a thread, or continue in this one - I'll be there.
One things for sure, Tim Zimmer isn't a fan of shockproof in the tranny.

TRE says this: REDLINE SHOCKPROOF There are concerns about using REDLINE SHOCKPROOF type gear oils inside manual transmissions. While this is truly an excellent product, it has been found that the heavy Teflon-like particles are quickly centrifuged out of the oil and will build up inside the center diff housing and around the synchronizers and inside of the gearshafts. After several oil changes this build up may block oiling passages inside the gearshafts that lubricate the needle bearings and can reduce the overall effectiveness of the synchronizers, leading to poor shift quality. Also this oil is has too high of a viscosity for winter use. Therefore we do not suggest using SHOCKPROOF in the transmission unless the transmission is to be serviced often or a dog box.

I've always used Heavy Shockproof and MT-90 mixed in my tranny. Cold shifting sucks, but once it warms up it's fine. Haven't had any issues that I'm aware of with oiling or anything. Fluid has been changed only a couple times over the past 3-4 years..

Here is part of my last post...

I switched to Diaqueen tonight and I can feel a difference. It is less notchy across the board and 1st & 2nd are easier to get into now, but not consistently. I would say it was worth getting that shockproof out of there, but not magic in a bottle by any means. I have run a blended mix of MT-90 & lightweight ever since I can remember so I guess I will see if my tranny lasts longer this time around...

I'm not eligible to log into the ECMlink forums. I bet it would be a great discussion.
