offroadsubaruguy Posted January 31, 2005 Share Posted January 31, 2005 ok, instead of using 80/90 like i know your supposed to in the tranny, i used what we had lying around..... 75/90 synthetic........ is this going to seriously screw my tranny? its a d/r in an 89 wagon.....

MorganM Posted January 31, 2005 Share Posted January 31, 2005 You could prolly throw half sand in there and that tranny would be okay Run it and find out. If it shifts poorly or just 'feels' bad to you, drain it and put in the right stuff. Quote Link to comment Share on other sites More sharing options...
85Sub4WD Posted January 31, 2005 Share Posted January 31, 2005 75w-90 is spec for the D/R trannies in all conditions, so you are probably going to improve it Quote Link to comment Share on other sites More sharing options...

Snowman Posted January 31, 2005 Share Posted January 31, 2005 I've been running 75w90 synthetic for three years with tremendous success. It's still as clear as the day it went in. Quote Link to comment Share on other sites More sharing options...
