just what the topic say. i wanna know what fluids are good for a oem lsd tranny? i dont know if it make that it is lsd or not. i've seen some cars have to use friction addatives for their factory lsd. right now i have redline fluid in it and i just wanna know if its okay or if theirs better fluids for it

 

From what I've heard it doesn't hurt to use the OEM fluid, but several ppl run the GM synchromesh (sp?), and as long as you're using the redline recommended to that particular tranny then it should be OK. If you do a search, especially in the ITR and RR forum archive, you'll find more info on this than you could ever want, since it's been discussed several times
