Am I the only one running shockproof? Shockproof is great in the transfer & rear diff but I didn't want to run it because of this, quoted from TRE's page: 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 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. 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. Are you running straight SP or is it mixed? Maybe this isn't so much of an issue when your mixing the SP with reg fluid? I know a bunch of higher hp guys on the link board had said they ran some version of a mix with the SP but I don't know if or how often they had the tranny out for service. Straight up lightweight shockproof. It is what Shep recommended for my power level.

Use the semi synthetic blend. Blue bottle. I run that straight in the tranny and t case, or mix with BG II as I mentioned above. Back from the dead, but I went to CTC to grab some 'blue bottle', and it now says " good for gl-4 and gl-5 applications". Aacckk, now did they just change the label and its still safe or what? CTC did not have any GL-4 only rated 75/90.

Want to resurrect this and see what others are using.
Shockproof in the xfer case and diff seems popular.
Mr Drew had informed me of this and also to use motul 300 75w90 in the trans.

I'm still using regular off the shelf gear oil, however mixed with Evo9 MR Diaqueen, in a 2:1 or 3:1 ratio. Transfer case uses straight regular off the shelf gear oil and so does the rear diff. My car is making 830WHP/650 ft lbs ,3300 lbs with me in it, running 10.0's and 149 MPH in the 1/4 on a stock syncro transmission, stock transfer case and stock rear diff, and it's still working for me.... I recommend the same mix to all my customers with high power level and it works for them too... These transmissions were designed in the 90's and used regular gear oil back then which worked well for longevity and durability. Along came the fancy synthetic fluids which IMHO just accelerate bearing, syncro and gear wear for a quicker shift. With the transmission I build these days with double syncros, new hub/sliders and proper clutch adjustment, fancy gear oil is simply not needed in order for it to shift nice at high rpm. People still ask me over and over again what I'm using in the transmission to keep it together. I keep telling everyone the same thing: regular gear oil will make the transmission last the longest
