pyromanic Posted January 9, 2005 Share Posted January 9, 2005 have an 89 wgn w/the dual range 5sp...when cold its a little notchy btwn 1st/2nd and 3rd/4th...after warm though its pretty smooth...the odometer shows 203k and i have no idea if or when the tranny fluid has ever been changed...would this be a good time to go the 50/50 route with synthetic and normal gear oil? and if so, suggestions would be nice alan Great coincedence, cause I just logged on to report on exactly that, but with an '86 D/R behind an EA 82. Bought the car recently from a very non mechanical fellow. Oil was dirty. Tranny felt just about done. Did the 50/50 thing just this evening and can't believe the difference. Like night and day. Much more quiet too. Shifts way smoother. I used the Redline shock proof light weight. Question? Do these fantastic results last?

starkiller Posted January 9, 2005 Author Share Posted January 9, 2005 red line shock proof? what weight? and mixed with what? Link to comment Share on other sites More sharing options...
BlueTrain Posted January 9, 2005 Share Posted January 9, 2005 i may have to try that mix. this past fall i changed out the gear oil with valvoline. now in the cold, it is very hard to shift unless i let car warm up for 5-7 minutes. last winter, no problems whatsoever. im thinking previous owner may have had synth in there. next stretch of semi-warm weather and im swapping the valvoline garbage out.

pyromanic Posted January 9, 2005 Share Posted January 9, 2005 red line shock proof? what weight? and mixed with what? Sorry, Like I said, Red line Shockproof Lightweight. (Not Ultralight) that's what it's called. Mixed 50/50 with regular Durex 80W-90 API GL 5. The Reline label says this: "can be rated as a 75W140 Gear Oil, which provides twice the viscosity in the thin layers between the gear teeth, but has the lower internal fluid friction of a 30 weight motor oil. I hope this mix is ok for year round use, but if someone tells me no, I can change. Sure has improved prefomance in this cold, cold weather. Did I do good? Bad? Don't know much, but I sure do know I don't want to f&$% up my already tired transmission. All comments are welcome, since if this combination is deemed innapropriate, I will simply use it as a flush since the tranny fluid was FILTHY.

hooziewhatsit Posted January 9, 2005 Share Posted January 9, 2005 I'm not sure about the mixing, however, I just recently put 100% redline 75w90NS in, and it's made a huge difference in cold shifting, and even shifting while warm. Link to comment Share on other sites More sharing options...
