I just put redline mt-90 gear oil in my tranny today good stuff now the test is in the morning.When it's cold

 

i use GM synchromesh

Remember we have copper synchros.

Some GL-5 gear oils COULD possibly harm your tranny..

I use full synthetic Mobile 1 90w Gear oil, you have some hard shifting in cold climates untill it warms up!

 

yea ive heard that mobil1 gear oils arent good for our trannies cuz it eats up the soft metals.....just thought id share


i know hyundai recommends gl-4

 

i havent heard anything about synthetic oils eating up metals. because synthetic oils are manmade and engineered to almost "soak" into the metal providing better lubricant. I have noticed smoother shifts with it!

 

Doesn't matter if it's synthetic or not, Do NOT use GL5 in our tranny's.

It WILL eat the brass in the synchros.

 

down here i use 75 -90w full synthetic at work, gen hyundai oil, and it great if u start getting hard shifts when gold, i also use it in m,y other car, with no probs laugh.gif

 

i use a mix of mobil 1 and the gm syncromesh

 

Bringing back an old topic, but I'm ordering my clutch today and and going to order some redline mt-90 fluid, but I can't seem to find how much the tranny takes, anyone know. I can't get hma to work cause IE has major spam and spyware issues, so I use mozilla, thanks.
