Has anyone run straight up lightweight shockproof in the transmission?

Hello.

No I have not heard of it. I'm using the MT90 in th Tranny and the Heavy Shockproof in the XCase and Rear-end.

Now let us know if you find the info or if you ever give it a try.

3 quarts sitting on the bench now. This is what shep recommended for my build. I will reply when I have some passes on it.

I've only heard of MT-90/Shockproof mixes from what I remember of the Digest's mid-90 days. Can't remember anyone running it straight-up.

But if anyone would know, it'd be Shep.

Are you going to be racing the car only? or is it a daily driver and is the tranny stock or built?

You will regret putting Shockproof in the tranny on a daily driver, especially in the winter.

1 qt mtl- and 1 qt mt-90 in tranny and shockproof in diff and transfercase.

I run MT-90 in the tranny and Shockproof Heavy in the x-fer case & rear diff. After reading the FAQ'a on TRE, Jack's, and Shep's sites, that seems to be the common consensus.

I also seem to recall something about NOT running Shockproof in the tranny because of the syncros.

Shep built the shafts up with double synchro 2nd 91 style gears and welded center diff.

Mostly track car, very little street duty.

I double checked with Shep trans today to confirm what they shipped me and they recommend lightweight shockproof for anything over 450 whp.

This is what I was referring to...

From: http://www.teamrip.com/manual_transmission_gear_oil_recommendation_info.html
Quote
There are concerns about using Redline's Shockproof type gear oils inside manual transmissions. While this is truly an excellent product, it has been found that the heavy paraffin-like particles are quickly centrifuged out of the oil and 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. Therefore we do not suggest using Shockproof in the transmission unless the transmission is to be serviced often or a dog box.


But then Jack has a slightly different perspective...

From: http://www.jackstransmissions.com/faq.php
Quote
If you are unable to locate Mitsubishi MR 6-speed oil from the Mitsubishi dealer, Redline Heavyweight Shockproof 50/50 mixed with Valvoline 80W-90 gear oil will also work just as well. For transfer cases and rear ends, use Redline Heavyweight Shockproof ONLY. <snip> DO NOT use Synchromesh, BG Synchroshift I or II, or Royal Purple. These fluids will destroy synchros and gears and void your warranty!

OMG! So all of those people that ran SynchroMesh and SynchroShift in their trannies for YEARS without problems were really destroying them from the inside out...

TeamRIP's advice sounds plausible, but I'd take that Jack's transmission's write-up with a grain (or a few pounds) of salt. Unless they're talking about the newer EVO trannies exclusively. Those are pretty proven products he's bashing.

I'm still puzzled, I've heard alot of people using synchromesh in their trannies mixed with something else and it's working fine.

It comes down to the power level you are running. If you're running stock boost, then Synchromesh might be OK (long term). As you increase power, you should go with a thicker, tougher, more viscous fluid.

I am running Redline 75W90NS and it has worked great for me. I would not even consider running Synchromesh or MTL or even MT-90 at the power level I'm at right now. I consider them all to be too thin for the job.

You can get Redline products from Pacific Mall @ Kennedy & Steeles in Markham. I just picked up some MTL to try and cure a 2nd gear grind in my Honda Accord.

I stopped using MTL and MT-90 in the DSM years ago. Now I won't use anything else than 2 parts BG Syncroshift II mixed with 1 part regular 75w90 gear oil.

Redline products from Pacific mall are probably (china imitations) I would only buy Redline products from JRP peformance in Mississauga.

It shifts really nice even above 8K. Although that's probably due to the twin disc as well.

Sorry to bring up an old thread but what oil should I use for a daily driver stock everything in winter time?

I was told to use Redline MT90 in tranny and Redline 75W90 or something in the tcase and rear end. Does this sound good for a daily driver or is there something better or a different combination?

Use BG Synchroshift in your tranny. I have it in my Talon and it shifts better in sub zero temperatures that any of the synthetics I've ever used. There is no need to have to granny shift the first 5 minutes after you head out like I had to with synthetics.

You'll get a ton of responses depending on people's personal preference, Greg.

Truth is, any 75w90 (I used Castrol SynTec) will do for the xfer case and the rear diff. I used GM SynchroMesh in my transmission and it seemed to work fine in the cold.

The fluids you're mentioning (BG, RedLine, Royal Purple, Amsoil, etc.) are probably better. But HOW MUCH better for the added cost?

Greg you say stock tranny but is the rest of the vehicle also stock? I wouldn't recommend the BG Synchroshift if the vehicle has been modified. Sure it will probably shift great in the winter, since its so thin but this also doesn't offer proper protection to the tranny. I use to run BG & it was more then likely the cause of a 3-4 slider failure in my tranny.

I don't personally drive in the winter, but the Redline MTL (slightly thinner then MT90) would probably be a good choice?

Hey Daren,

My car is completely stock. I'm just looking to change the fluids as they have probably never been changed.

Thanks.
